}}

== Description ==

The '''{{Specs|name}} '''originated from Sweden's requirement in 1949 for an assault gun, that was meant to be light, cheap and small. The Ikv 72 fulfilled this request. But in 1956 the tank was upgraded to the Ikv 102 standard. Soon, this tank was also improved, and the Ikv 103 was born. Compared to the original Ikv 72, it featured a new 105mm cannon instead of the original 75mm. A new armored roof protected the crew, the original engine was replaced by the Volvo B42 and the air intake was moved to grills on the rear of the vehicle, instead of through the crew compartment.

Introduced in [[Update 1.97 "Viking Fury"]] and just like other Swedish assault guns, the '''Infanterikanonvagn 103 '''is a very small vehicle, with thin armour and good firepower. Featuring a 105mm gun with a HEAT-FS round, which is unusual at such low BR, the tank is capable of dealing with tanks like the T95. Although it has neutral steering, the tank mobility is mediocre, it lacks an MG, which is necessary to destroy fences that may stop your HEAT shells and the armour is very unreliable, it can even be penetrated by 12.7mm HMGs, making the tank extremely vulnerable to aircraft or nearby artillery.

== General info ==
=== Survivability and armour ===
{{Specs-Tank-Armour}}


The armour of the Ikv 103 is between 5 and 18.5 mm of thickness. This kind of armour shouldn't be considered as survivable since any round will penetrate it and destroy most of what's left inside the SPG. One could argue, that the front is decently protected, but there is a giant visible hole in front of the gunner, which can be hit by a machine gun easily.

Since the hole exists, any chemical ammunition will instantly destroy the {{PAGENAME}} regardless of where it hits. It is heavily recommended to avoid any form of damage since artillery fire is guaranteed to destroy the SPG even in the case of a close miss.

The thin side armour has the occasional ability to result in overpenetration and often fails to set off APHE fuses, but any frontal armour will activate them.

The SPG is also incredibly weak against aerial attacks. The roof won't protect from any calibre larger than a 7.7 mm MG, and even that much is not guaranteed. But, since it actually exists, it makes less knowledgeable fighters attack something else instead, as they often look for an open-topped tank first.

Thanks to the short length of the rounds, as well as compact storage on the hull floor, ammunition explosions are quite rare. Due to this, taking the maximum amount of ammunition isn't something to frown upon.

{{tankMobility|abMinHp=190|rbMinHp=133}}

The Ikv 103 sports a good engine with a fairly high RPM giving it a lot of torque for climbing a lot of obstacles and average terrain. Although the top speed never exceeds 50 km/h, the Ikv 103 cruises comfortably around 40-45 km/h on a straight line and 25-35 km/h on uneven terrain, depending on the driving level and modules unlocked, no matter the surface below it. The vehicle finds no issue traversing snowy and sandy terrain thanks to the low weight and good track surface, but struggles in deep waters due to the low chassis it sports. The reverse rate of the Ikv 103 is also quite good at 11 km/h. Even if this speed can't hold a candle to the regular speed the 103 has, the reverse rate is still enough to safely peek over hills and reverse back into cover before getting fired upon.

{{main|kan Ikv 103 (105 mm)}}

The Ikv 103 is outfitted with a 105 mm cannon firing heavy shells with a reload of 8 to 10 seconds depending on crew qualifications. This cannon is unusually short for its calibre, firing heavy shells with low-velocity. The gun is aimed manually without the help of electrical equipment, resulting in a slow traverse rate. At maximum, the gun traverses at 8° per second, resulting in many deaths at closer ranges. The stock gun accuracy is above average.

The gun has a significant recoil, which can mess with the aim in RB/SB and will slightly move the tank backwards. The recoil can also be used as an advantage to fly off the hill as fast as possible before an enemy started firing back.

Although the early psgr m/49 lacks significant amount of angled penetration and post-penetration damage, it works just fine at medium to long range. It can also be easily launched over cover at 450 m range while the SPG is fully concealed, which makes it useful in any situation. The later slpsgr m/65 HEATFS round packs up to 400 mm of flat penetration, generally penetrating anything it sees and making the post-penetration much deadlier than before. This later shell also features a higher velocity than the previous round, so it might actually hit moving targets.

Unfortunately, a lot of heavy tanks have near-impenetrable machine gun ports and even HEATFS will fail to get through them, so the gun cannot be fired entirely without care. If the {{PAGENAME}} is used as a backup along with the 7.0 lineup, it will often fail to penetrate or bounce off the turret of many US heavy tanks due to their sheer thickness.

This SPG uses X1.9-3.5 scope again unlike the [[Pvkv m/43 (1963)|Pvkv m/43]], so it's difficult for it to fight at long range.

This makes the gun most effective at medium ranges, where the traverse is ideal, and the shell velocity isn't crucial. It should be noted that the incredible gun depression allows the Ikv 103 to fire directly from extreme angles allowing it to suddenly engage targets in RB without the risk of overexposing the tank, something which becomes incredibly useful to increase the vehicles survivability.

==== Ammunition ====

* '''psgr m/49''', HEAT - This stock shell offers great penetration values and should give you no trouble penetrating the upper glacis of common enemies like the Panther and Pershing series tanks. Even heavy tanks such as the Tiger II will also be vulnerable to this shell. Though it does suffer from the usual characteristics of HEAT which is the low muzzle velocity and sensitive fuse.
* '''sgr m/34 LT''', HE - This shell is able to destroy some medium and heavy tanks in one hit by attacking their roof, but some heavy tanks in up-tier already have 26 mm RHA thick roofs, making them effectively invulnerable to it.
* '''slpsgr m/65''', HEATFS - The HEATFS shell is an upgrade compared to the regular HEAT shells. The penetration is most noticeably increased. It also has a slightly faster muzzle velocity, which is helpful for sniping. However the major downside is its cost. In most situations, the stock HEAT shell will suffice.
* '''rökgr m/49''', Smoke - The smoke shell will help blind enemies to allow you to move behind cover.

== Usage in battles ==


The Ikv 103 is a nimble vehicle with a small silhouette compared to its peers. The lightweight and powerful gun set it apart from other vehicles at the battle rating.

The general playstyle can be compared to the Jpz 4-5 found in the German tech tree, as the vehicle has to make use of positioning rather than frontal survivability. The Ikv 103 can't use common sniping locations effectively since any form of enemy retaliation will destroy the vehicle completely. Instead, the 103 needs to drive full speed to various locations where enemies are unlikely to expect danger. Although this playstyle requires a lot of map knowledge, the reward is quite high for a successful flank, thanks to the devastating cannon the Ikv 103 carries.

Thanks to the light vehicle weight and strong engine, the Ikv 103 is also able to climb a lot of obstacles, something that helps a lot when fighting on bad terrain. However, maps that lack terrain entirely cripple the 103's performance quite significantly, since the tank cannot hide, resulting in a lot of face-to-face engagements, which the Ikv 103 almost always lose.

In AB, when it's impossible to find a good hill or the enemy is just too good, one can use this SPG as a mortar to bombard enemy tanks at about 450 m range with HEAT straight out of cover. Any cover that completely covers the SPG will work at this point, whether it's a random rock or terrain. It's also technically possible to fire over shallow hills while standing on them at ranges of about 300 m, but this is not entirely safe and constantly leads to situations, in which {{PAGENAME}} is flanked or sniped. This playstyle works quite well over flat plains and some sniping hills, which are generally incapable of stopping shells with low velocity, but will likely block high-velocity APHE of all enemy tanks. Use binoculars to track enemy movements and to pre-aim. Be careful to not provoke other HEAT tanks into an artillery battle unless you are sure about your aim, as the {{PAGENAME}} won't survive even a single HE/HEAT hit.

=== Pros and cons ===


'''Pros:'''

* Excellent HEAT round for its rank, able to penetrate the upper glacis plate of the Tiger II
* Excellent upgraded HEATFS round, useful even way outside of tanks own rank (technically can penetrate [[T95]])
* Good speed, able to secure crucial positions or even flank the enemy
* Neutral steering
* Small silhouette, can completely hide behind medium tanks hull or cover
* Incredible gun depression
* Due to having a roof, will not be as interesting to fighters as previous SPG models (although it won't really save from them)
* Can work as artillery in AB, with not many tanks being able to do anything about it, but to ask for an air raid

'''Cons:'''

* Poor armour, counts as open-topped, sides able to be penetrated even by rifle-calibre bullets, especially behind the tracks - Ikv 103 must rely on stealth
* No MG to destroy light fences that can fuse the HEAT shells
* Will struggle through any obstacles due to its low mass
* Slow gun traverse, makes aiming in CQB or at a moving target harder
* Vehicle reverses slightly when firing, forcing you to reacquire range of target after every shot
* HEAT shell has a relatively low muzzle velocity, may be hard to fire accurately over long ranges
* HEATFS shell is expensive and should thus be used conservatively

== History ==


The [[Ikv 72|Infanterikanonvagn 72]] was a project started in 1949 by Sweden for an assault gun. The intended role of this vehicle was to support the infantry in the attack, replacing towed artillery guns. The design was to be small, and of light weight, around 6 tons. This was to reduce costs so a larger amount could be produced. The first prototype from Landsverk, completed in 1950, was armed only with three machine guns. This was insufficient, and it was re-armed with a 75 mm cannon, the same gun from the [[Strv m/42 EH|Strv m/42]]. It was a small, lightly armoured vehicle, with a casemate superstructure housing the 75 mm gun. It had a crew of 4, and it was open topped. Starting in 1956, the Ikv 72 was upgraded to the Ikv 102 standard. This upgrade added an armoured roof for the crew compartment and a 105 mm gun replaced the 75 mm gun. The Ikv 102, in turn, was upgraded to the Ikv 103 standard. The Ikv 103 featured an improved engine, the Volvo B42 engine. The air intake was moved to grills on the rear of the vehicle, instead of through the crew compartment.

=== [[wt:en/news/6600-development-ikv-103-heat-mortar-en|Devblog]] ===
In 1949, the procurement division of the Swedish army placed an order for the development of a light assault self-propelled gun to substitute the [[Sav m/43 (1946)|Sav m/43]] SPG. Three companies took on the work: AB Landsverk took on the development of the platform, Volvo was responsible for the powertrain, and Bofors for the armament. In fact, three versions of the vehicle for different purposes were planned at first: one with a 75 mm cannon, a machine-gun-equipped modification, and also a special one that was intended for the deployment of specific weaponry, such as flamethrowers and rocket launchers. Thus, a light (merely eight tonnes in all), tracked infantry-support vehicle was produced, with an open cabin and bulletproof armour.

In 1952, a cannon-equipped version, under the designation the Ikv 72 (short for "infanterikanonvagn", meaning "cannon-equipped infantry-support vehicle" in Swedish), was put into service. A little later, the SPGs were re-equipped with 105 mm howitzers and the cabin was retrofitted with a roof, which could protect the crew from bullets and shrapnel. This modification received the designation Ikv 102. Meanwhile, the Swedish army ordered another series of the vehicle with an upgraded chassis to allow installation of a new air-cooled engine, while the gun and the armour remained the same as the Ikv 102's. This new version was designated Ikv 103. The Ikv 102 and 103 SPGs remained in use by the Swedish army until the mid-1970s, when they were replaced with the [[Ikv 91]] SPG.

== Description ==

The '''{{Specs|name}}''' was a Swedish light tank in service with the Swedish Army between 1958 to 1984. It was designed in 1957, using the older chassis of the Strv m/42 TH and TV that were considered obsolete in the mid 1950s. The {{PAGENAME}} was intended to support the recently acquired [[Strv 81]]. The turret was completely redesigned to be able to fit a high-velocity 75 mm tank gun based on a modified [[Lvkan m/37 A (75 mm)|Lvkan m/37]] anti-aircraft gun which was also to be used on the [[Pvkv II]] tank destroyer project. The {{PAGENAME}} served in armoured brigades up until 1967 when the [[Strv 103 (Family)|Strv 103]] took over the role and the {{PAGENAME}} was transferred to infantry support. The {{PAGENAME}} comes in two versions, 74 H and 74 V, their only difference being internal layout and transmission. The Strv 74 V would serve until 1981, and the remaining 74 H would serve until 1984 when they would be phased out in favour of the [[Ikv 91]]. The turrets would become coastal defences similar to the older [[Strv m/41 S-II|Strv m/41]] turrets that became static defenses around airfields.

Introduced in [[Update 1.97 "Viking Fury"]], the Strv 74 is a unique light tank developed primarily for combat in hilly terrain. With its excellent gun depression, this light tank can completely conceal the majority of its profile behind obstructions, revealing only its small turret to fight enemies when they are in sight. With its armour-piercing discarding-sabot (APDS) ammunition penetrating 247 mm of armour at point-blank range, players will be happy to learn that fighting even the strongest adversary on the battlefield is effortless. However, the light tank has a large profile, which is an issue on city maps. Furthermore, a lack of mobility combined with the slow reverse speed makes it difficult to retreat in difficult situations.

== General info ==
=== Survivability and armour ===
{{Specs-Tank-Armour}}


Like the rest of the Swedish line, the armour on the Strv 74 should not be counted on to bounce a shot. It uses the same hull of the Strv m/42 (The Lago I)- a hull that at its BR the armour is considered fairly average. The new modern turret is extremely massive- almost the same size of the hull itself! This size makes hiding behind low objects impossible.

The turret does however have one niche trick up its sleeve, the back of the turret. An opponent who isn't well versed in the Swedish tree would assume the the back of the turret would house ammunition. However for the Strv 74, all the ammo (excluding the ready rack) is stored in the hull instead. With the inclusion of the 10 mm back plate, the turret back can act as a shot trap when caught off guard, allowing the Strv 74 to react accordingly - by returning fire or deploying one of the 2 smoke barrages and relocating.

{{Specs-Tank-Mobility}}


{{tankMobility|abMinHp=527|rbMinHp=301}}

=== Modifications and economy ===
{{Specs-Economy}}

After Parts and FPE, it can be advisable to focus on mobility upgrades, given the Strv's poor power-to-weight ratio and top speed. Another useful modification is the 7,5 cm slpprj m/49 APDS shell, which gives this vehicle enough penetration to go through almost any armour that it might face.

{{main|ksp m/36 (8 mm)}}

The Strv 74 has a pair of 8 mm ksp m/36 machine guns, one mounted coaxially and the other mounted upon the commander's cupola. The machine guns have very low penetration and mass making it harder to use than some of its counterparts. They are best used deterring aircraft as your lightly armoured top is often the target of aircraft with heavy armament. The roof armament is immediately unusable if the commander has been killed or forced to take on the gunner or driver's position.

== Usage in battles ==


'''Protection:'''

Despite a decent amount of armour angling, the Strv 74 is weakly protected. Most enemy shells will be able to penetrate its armour with ease, which means that it is best to avoid enemy fire whenever possible. This vehicle is certainly no heavy tank, and rushing into risky situations, spearheading a push, or exposing the tank's profile is generally unadvisable. The tank's large side profile and tall turret make it quite visible on the battlefield as well, so it might not always be possible to find suitable cover.

Additionally, the internal layout of the vehicle is fairly cramped. With three crew members located in the turret, an APHE shell fired there can easily knock out enough crew members to destroy the vehicle. A shot fired into the front of the tank is likely to do the same. This makes it even more important to avoid enemy fire.

'''Firepower:'''

However, the tank's cannon is quite powerful, and able to punch above its weight, with a more-than-capable APHE shell. The upgraded APDS shell gives the gun enough penetration to go through almost any armour at this rank and makes it effective even in full uptiers.

The Strv has an outstanding -15 degrees of gun depression, which allows it to fire from behind ridges and hills that most other vehicles would never be able to utilise effectively. Be careful though: the tank has a prominent turret and a large turret cupola, which makes it difficult to fire from ridgelines without being spotted and fired upon.

'''Mobility:'''

The Strv has a low power-to-weight ratio compared to its peers, and a lower top speed as well. It can't zoom around the battlefield or quickly relocate like some vehicles can, and long flanking manoeuvres will also be difficult. The Strv 74 has a mediocre reverse speed, which should be noted when firing from behind ridgelines; the vehicle can be slow to reverse back behind cover after firing a shot.

=== Pros and cons ===


'''Pros:'''

* Incredible gun depression of -15°
* APDS round has 248 mm of penetration at 500 m
* Starts stock with the effective APCBC round found on the [[Pvkv II]]
* Quick gun elevation and depression

'''Cons:'''

* Turret is a massive target
* APDS shell is a tier IV modification
* Outdated chassis - narrow tracks and thin armour
* Slow reverse of -4 km/h
* Immensely reduced mobility due to increased weight
* Commanders machine gun reduces visibility to the right in simulator battles
* APHE has difficulty knocking out big heavy tanks with spaced-out crew

== History ==


'''Development'''

After the end of World War 2, the only medium tank Sweden had was the [[Strv m/42 EH|Strv m/42]]. This vehicle was no longer capable, and had become obsolete. The Swedish military considered buying French [[AMX-13]]'s, but decided to instead buy the British [[Strv 81|Centurion]]. Sweden had a need for a light tank still, and decided that designing a new light tank would take too long and be too expensive, so instead they decided to create a new light tank with the chassis of the Strv m/42. The Strv m/42 had been retired in 1950, and in 1953 the process of upgrading the tanks was started. First, putting the turret of the AMX-13 on the Strv m/42 chassis was considered but was quickly deemed unfeasible as the turret rings had different sizes and the necessary modifications would have made the project far too expensive and time consuming. Instead it was decided to develop a brand new turret. It was armed with a 7,5 cm lvkan m/36 anti-aircraft gun modified for use in a tank. The Swedish military supported this design because it would be cheaper than buying a foreign tank, and ordered two prototypes in 1954. The [[Strv m/42 EH]] was not chosen to hold the new turret as its engine was unreliable, but the Strv m/42 TH and TV were chosen to house the new turret.

'''Design'''

The turret had a unique shape, it was heavily sloped on all sides, but the armour was at most only 20 mm thick. The armour was kept to a minimum as the suspension would not be able to handle more weight. It shared many components with the Centurion. The back of the turret contained a Volkswagen engine used for heating and power. The gun could depress to an impressive -15 degrees. The chassis had to be modified in order to handle the increased weight of the new turret. The shock absorbers were replaced, the steering mechanism was changed, the driver's hatch was changed, and the tracks were widened to decrease ground pressure. The twin Scania-Vabis 603 engines of the Strv m/42 TH and TV were replaced by newer 607 engines featuring direct fuel injection, this increased the horsepower, and increased reliability at low temperatures. Smoke dischargers, a spare road wheel, and a bustle rack were added to the turret. The vehicle carried a crew of 4 men.

'''Production and Service'''

225 Strv m/74 were ordered by the Swedish military, and the order was spread between Hägglunds & Söner and Landsverk. There were two major variants, the Strv m/74 H (based on the Strv m/42 TH) and the Strv m/74 V (based on the Strv m/42 TV). The only major differences between the two was the different gearboxes which resulted in slightly different internal layout and ammo storage solutions. Both V and H variants were upgraded with spare Ra 121 or Ra 421 radios later in their service life and were redesignated as Strv 742 or 743 depending on the type of new radio they received. The [[Strv 74]] was designated as a light tank until the 1960's, when it was re-designated as an infantry support vehicle. When the [[Ikv 91]] entered service, the numbers of Strv 74 decreased as the [[Ikv 91]] could do everything better than the Strv 74. The Strv 74 was fully retired from service by 1984, and some of the turrets were used as static fortifications until the late 1990's.

== General info ==
=== Survivability and armour ===
{{Specs-Tank-Armour}}


The M47's armour is a middle point between the M26 and an M48, it has decent hull armour which is able to stop full calibre solid shots from almost all vehicles it will face. However, it is not able to withstand sub-calibres like British APDS. Turret is inconsistent when it comes to full calibre and sub-calibres. Turret mantlet is able to withstand calibres lower than 105 mm but cheeks may even stop 122 mm. However they may not be able to stop sub-calibres from almost all calibres. Armour should not be relied on most of the cases due to inconsistency against threats seen in combat. However, this does not mean the armour should not be used at all. When facing Soviet and American tanks, armour is sufficient to completely shatter or partially stop the shell, this is due to full calibre APHE and APCBC have relatively low penetration (215 mm - 250 mm). The story changes when facing British APDS from 20-pdr (84 mm) to 120 mm. They have an equivalent or higher penetration than the M47 (105/55) APDS, meaning they will easily penetrate you without effort. Now, there are some aspects when it comes to APDS. Due to being sub-calibre, they have penetration over post-penetration effects. All the spalling is dependent on the armour thickness. This can be considered good or bad depending on where the APDS is being fired at. Hits to the hull frontal plate will most likely kill your driver and loader (if hit on the right side seen from the front) or gunner and commander (if hit on the left side seen from the front). Turret hits are often single-shot kills if fired in the right places. In a 60° frontal arc, all hits will take at most 2 crew members unless it is a high calibre round like the [[Conway]]'s 120 mm. Past 60°, all hits are most likely to be single-shot kill, specially if the hit is made at a turret side as the breech is not big enough to stop the spalling. Hits on the turret back are confirmed kills, however, hits on the engine deck can be painful due to fire but will not instantly destroy the M47. The engine and transmission are big enough to stop all spalling and rounds it will see except darts.

=== Mobility ===
{{Specs-Tank-Mobility}}


Mobility wise, the M47 is a fatter M26. Not too fast but not too slow either. It has a powerful engine that is able to pull and push almost all tanks in the battlefield while being able to maintain adequate mobility. It does not have neutral steering per se as it is not fully on its own axis. However it does have a really good reverse speed (for its size) as well as acceleration for both forward and reverse gears. Top speed is higher than the M26 but is not too fast, expect from a Patton tank.

{{main|OTO Melara 105/55 (105 mm)}}

This specific M47 is armed with the OTO Melara 105/55 cannon, the only M47 in-game to have a 105 mm gun. It is similar to the L7A3 Royal Ordnance 105 mm gun seen on other vehicles ([[Centurion Mk 10]], [[Leopard 1]], [[Vickers MBT]]) and the M68 105 mm gun ([[M60 (Family)|M60A1-A3]]). However, its handling is similar to the OTO Melara 105/52 of the Centauro, mainly for using exactly the same ammunition.

==== Ammunition ====
This M47 is the most powerful M47 seen in-game firepower-wise. It has the same ammunition as the [[Centauro]].

* M392A2: despite being APDS and the stock round, this round is one of the most powerful sub-calibre rounds the Italians have access to at Rank 5. The penetration, flight speed and post-penetration effect are really great for beating almost all tanks it faces with exception of the T-55AM-1. This round is underestimated for the fact it does not have the same penetration the M456 has. However it comes more in handy to use APDS most of the time than HEATFS mainly for the fact that it can be used easier for longer engagements and will not detonate with trees and bushes.
* M393A2: the HESH round is 90% of the time useless unless trap shots are involved. The use for it is really situational and it is much better to carry APDS or HEATFS for all anti-tank purposes.
* M456: this is the pinnacle of heavy armour destroying, mainly for the fact that it has a continuous penetration through all its flight time. This is not recommended to be carried as the main shell for the previous statements. However it is recommended to carry some to defeat heavy armour the APDS is unable to penetrate.

== Usage in battles ==


The M47 is a slow pushing tank with a powerful anti-tank gun. It should not be used as frontline tank but rather as support tank. Its powerful gun is more than capable of dealing with 90% of the tanks it will see at any range. However, as you don't have enough armour to sustain HEATFS shells at that tier, you need to stay aware of your surroundings at all times. This will impact your combat performance and you'll have to adapt your tactics depending on the map. Search for sniping spots with available cover nearby, watch the inclination because your gun can't depress too much (-5°).

'''List of opponents important notes when facing frontally:'''

== History ==

The story of the Italian M47 (105/55) starts during the 5th October 1952, Italy was modernizing its tanks and replacing the old M26 tanks they had in service. The Italian M47s came from America in the form of the MAP (Military Assistance Program), which foresaw the Italian army getting equipped with new M47 tanks, being delivered up until the 29th of December of that year when deliveries would finally be complete. Italy would end up using over 1,000 units in various different regiments. They would go on to serve in the Italian army for many years, until they were put out of service in favour of the American M60.

The story of the M47 (105/55) upgrade would happen during the 1970s, OTO Melara had proposed to modernize Italian M47s by replacing its original M36 90 mm cannon with an OTO Melara 105 mm cannon. The 105 mm cannon was originally a 90 mm that was modified by OTO engineers, making the cannon longer and wider, which ended up allowing the new cannon to have a length of 55 calibres, instead of the 52 calibres of the 105 mm L7 cannons. This was mainly done to save money as OTO didn't want to pay for rights for the construction. The new cannon installed onto the M47 could fire a variety of munitions, such as HEATFS, APDS and HESH. Other changes included a new Continental ADVS 1750 diesel engine, already present on M60 tanks, that replaced the older more unreliable one. The new ADVS engine would have a more efficient diesel propulsion system, which was favoured. Although it was inferior in terms of overall output from the original engine, it being diesel-powered was the main reason it was chosen. Lastly, there would be installation at the rear of the vehicle that gave the hull a thermal suppressor that would reduce IR signatures of the tank. The tank was a great success during tests, with both Spanish and Pakistani crowds viewing the progress, who would be very interested in this vehicle, sadly the M47 upgrade never got picked up by the Italian army. It is unknown as to why, some have said due to costs, others have said it was political as Italy was setting its sights for the M60 tank, so it would've been much better to keep ties with America stronger by purchasing their vehicles, which Italy eventually bought later down the line to replace the M47.

== Description ==

The '''{{Specs|name}}''' was a Swedish light tank in service with the Swedish Army between 1958 to 1984. It was designed in 1957, using the older chassis of the Strv m/42 TH and TV that were considered obsolete in the mid 1950s. The {{PAGENAME}} was intended to support the recently acquired [[Strv 81]]. The turret was completely redesigned to be able to fit a high-velocity 75 mm tank gun based on a modified [[Lvkan m/37 A (75 mm)|Lvkan m/37]] anti-aircraft gun which was also to be used on the [[Pvkv II]] tank destroyer project. The {{PAGENAME}} served in armoured brigades up until 1967 when the [[Strv 103 (Family)|Strv 103]] took over the role and the {{PAGENAME}} was transferred to infantry support. The {{PAGENAME}} comes in two versions, 74 H and 74 V, their only difference being internal layout and transmission. The Strv 74 V would serve until 1981, and the remaining 74 H would serve until 1984 when they would be phased out in favour of the [[Ikv 91]]. The turrets would become coastal defences similar to the older [[Strv m/41 S-II|Strv m/41]] turrets that became static defenses around airfields.

Introduced in [[Update 1.97 "Viking Fury"]], the Strv 74 is a unique light tank developed primarily for combat in hilly terrain. With its excellent gun depression, this light tank can completely conceal the majority of its profile behind obstructions, revealing only its small turret to fight enemies when they are in sight. With its armour-piercing discarding-sabot (APDS) ammunition penetrating 247 mm of armour at point-blank range, players will be happy to learn that fighting even the strongest adversary on the battlefield is effortless. However, the light tank has a large profile, which is an issue on city maps. Furthermore, a lack of mobility combined with the slow reverse speed makes it difficult to retreat in difficult situations.

== General info ==
=== Survivability and armour ===
{{Specs-Tank-Armour}}


Like the rest of the Swedish line, the armour on the Strv 74 should not be counted on to bounce a shot. It uses the same hull of the Strv m/42 (The Lago I)- a hull that at its BR the armour is considered fairly average. The new modern turret is extremely massive- almost the same size of the hull itself! This size makes hiding behind low objects impossible.

The turret does however have one niche trick up its sleeve, the back of the turret. An opponent who isn't well versed in the Swedish tree would assume the the back of the turret would house ammunition. However for the Strv 74, all the ammo (excluding the ready rack) is stored in the hull instead. With the inclusion of the 10 mm back plate, the turret back can act as a shot trap when caught off guard, allowing the Strv 74 to react accordingly - by returning fire or deploying one of the 2 smoke barrages and relocating.

=== Modifications and economy ===
{{Specs-Economy}}

After Parts and FPE, it can be advisable to focus on mobility upgrades, given the Strv's poor power-to-weight ratio and top speed. Another useful modification is the 7,5 cm slpprj m/49 APDS shell, which gives this vehicle enough penetration to go through almost any armour that it might face.

{{main|ksp m/36 (8 mm)}}

The Strv 74 has a pair of 8 mm ksp m/36 machine guns, one mounted coaxially and the other mounted upon the commander's cupola. The machine guns have very low penetration and mass making it harder to use than some of its counterparts. They are best used deterring aircraft as your lightly armoured top is often the target of aircraft with heavy armament. The roof armament is immediately unusable if the commander has been killed or forced to take on the gunner or driver's position.

== Usage in battles ==


'''Protection:'''

Despite a decent amount of armour angling, the Strv 74 is weakly protected. Most enemy shells will be able to penetrate its armour with ease, which means that it is best to avoid enemy fire whenever possible. This vehicle is certainly no heavy tank, and rushing into risky situations, spearheading a push, or exposing the tank's profile is generally unadvisable. The tank's large side profile and tall turret make it quite visible on the battlefield as well, so it might not always be possible to find suitable cover.

Additionally, the internal layout of the vehicle is fairly cramped. With three crew members located in the turret, an APHE shell fired there can easily knock out enough crew members to destroy the vehicle. A shot fired into the front of the tank is likely to do the same. This makes it even more important to avoid enemy fire.

'''Firepower:'''

However, the tank's cannon is quite powerful, and able to punch above its weight, with a more-than-capable APHE shell. The upgraded APDS shell gives the gun enough penetration to go through almost any armour at this rank and makes it effective even in full uptiers.

The Strv has an outstanding -15 degrees of gun depression, which allows it to fire from behind ridges and hills that most other vehicles would never be able to utilise effectively. Be careful though: the tank has a prominent turret and a large turret cupola, which makes it difficult to fire from ridgelines without being spotted and fired upon.

'''Mobility:'''

The Strv has a low power-to-weight ratio compared to its peers, and a lower top speed as well. It can't zoom around the battlefield or quickly relocate like some vehicles can, and long flanking manoeuvres will also be difficult. The Strv 74 has a mediocre reverse speed, which should be noted when firing from behind ridgelines; the vehicle can be slow to reverse back behind cover after firing a shot.

=== Pros and cons ===


'''Pros:'''

* Incredible gun depression of -15°
* APDS round has 248 mm of penetration at 500 m
* Starts stock with the effective APCBC round found on the [[Pvkv II]]
* Quick gun elevation and depression

'''Cons:'''

* Turret is a massive target
* APDS shell is a tier IV modification
* Outdated chassis - narrow tracks and thin armour
* Slow reverse of -4 km/h
* Immensely reduced mobility due to increased weight
* Commanders machine gun reduces visibility to the right in simulator battles
* APHE has difficulty knocking out big heavy tanks with spaced-out crew

== History ==


'''Development'''

After the end of World War 2, the only medium tank Sweden had was the [[Strv m/42 EH|Strv m/42]]. This vehicle was no longer capable, and had become obsolete. The Swedish military considered buying French [[AMX-13]]'s, but decided to instead buy the British [[Strv 81|Centurion]]. Sweden had a need for a light tank still, and decided that designing a new light tank would take too long and be too expensive, so instead they decided to create a new light tank with the chassis of the Strv m/42. The Strv m/42 had been retired in 1950, and in 1953 the process of upgrading the tanks was started. First, putting the turret of the AMX-13 on the Strv m/42 chassis was considered but was quickly deemed unfeasible as the turret rings had different sizes and the necessary modifications would have made the project far too expensive and time consuming. Instead it was decided to develop a brand new turret. It was armed with a 7,5 cm lvkan m/36 anti-aircraft gun modified for use in a tank. The Swedish military supported this design because it would be cheaper than buying a foreign tank, and ordered two prototypes in 1954. The [[Strv m/42 EH]] was not chosen to hold the new turret as its engine was unreliable, but the Strv m/42 TH and TV were chosen to house the new turret.

'''Design'''

The turret had a unique shape, it was heavily sloped on all sides, but the armour was at most only 20 mm thick. The armour was kept to a minimum as the suspension would not be able to handle more weight. It shared many components with the Centurion. The back of the turret contained a Volkswagen engine used for heating and power. The gun could depress to an impressive -15 degrees. The chassis had to be modified in order to handle the increased weight of the new turret. The shock absorbers were replaced, the steering mechanism was changed, the driver's hatch was changed, and the tracks were widened to decrease ground pressure. The twin Scania-Vabis 603 engines of the Strv m/42 TH and TV were replaced by newer 607 engines featuring direct fuel injection, this increased the horsepower, and increased reliability at low temperatures. Smoke dischargers, a spare road wheel, and a bustle rack were added to the turret. The vehicle carried a crew of 4 men.

'''Production and Service'''

225 Strv m/74 were ordered by the Swedish military, and the order was spread between Hägglunds & Söner and Landsverk. There were two major variants, the Strv m/74 H (based on the Strv m/42 TH) and the Strv m/74 V (based on the Strv m/42 TV). The only major differences between the two was the different gearboxes which resulted in slightly different internal layout and ammo storage solutions. Both V and H variants were upgraded with spare Ra 121 or Ra 421 radios later in their service life and were redesignated as Strv 742 or 743 depending on the type of new radio they received. The [[Strv 74]] was designated as a light tank until the 1960's, when it was re-designated as an infantry support vehicle. When the [[Ikv 91]] entered service, the numbers of Strv 74 decreased as the [[Ikv 91]] could do everything better than the Strv 74. The Strv 74 was fully retired from service by 1984, and some of the turrets were used as static fortifications until the late 1990's.

== Description ==

The '''{{Specs|name}} '''originated from Sweden's requirement in 1949 for an assault gun, that was meant to be light, cheap and small. The Ikv 72 fulfilled this request. But in 1956 the tank was upgraded to the Ikv 102 standard. Soon, this tank was also improved, and the Ikv 103 was born. Compared to the original Ikv 72, it featured a new 105mm cannon instead of the original 75mm. A new armored roof protected the crew, the original engine was replaced by the Volvo B42 and the air intake was moved to grills on the rear of the vehicle, instead of through the crew compartment.

Introduced in [[Update 1.97 "Viking Fury"]] and just like other Swedish assault guns, the '''Infanterikanonvagn 103 '''is a very small vehicle, with thin armour and good firepower. Featuring a 105mm gun with a HEAT-FS round, which is unusual at such low BR, the tank is capable of dealing with tanks like the T95. Although it has neutral steering, the tank mobility is mediocre, it lacks an MG, which is necessary to destroy fences that may stop your HEAT shells and the armour is very unreliable, it can even be penetrated by 12.7mm HMGs, making the tank extremely vulnerable to aircraft or nearby artillery.

== General info ==
=== Survivability and armour ===
{{Specs-Tank-Armour}}


The armour of the Ikv 103 is between 5 and 18.5 mm of thickness. This kind of armour shouldn't be considered as survivable since any round will penetrate it and destroy most of what's left inside the SPG. One could argue, that the front is decently protected, but there is a giant visible hole in front of the gunner, which can be hit by a machine gun easily.

Since the hole exists, any chemical ammunition will instantly destroy the {{PAGENAME}} regardless of where it hits. It is heavily recommended to avoid any form of damage since artillery fire is guaranteed to destroy the SPG even in the case of a close miss.

The thin side armour has the occasional ability to result in overpenetration and often fails to set off APHE fuses, but any frontal armour will activate them.

The SPG is also incredibly weak against aerial attacks. The roof won't protect from any calibre larger than a 7.7 mm MG, and even that much is not guaranteed. But, since it actually exists, it makes less knowledgeable fighters attack something else instead, as they often look for an open-topped tank first.

Thanks to the short length of the rounds, as well as compact storage on the hull floor, ammunition explosions are quite rare. Due to this, taking the maximum amount of ammunition isn't something to frown upon.

=== Mobility ===
{{Specs-Tank-Mobility}}


{{tankMobility|abMinHp=190|rbMinHp=133}}

The Ikv 103 sports a good engine with a fairly high RPM giving it a lot of torque for climbing a lot of obstacles and average terrain. Although the top speed never exceeds 50 km/h, the Ikv 103 cruises comfortably around 40-45 km/h on a straight line and 25-35 km/h on uneven terrain, depending on the driving level and modules unlocked, no matter the surface below it. The vehicle finds no issue traversing snowy and sandy terrain thanks to the low weight and good track surface, but struggles in deep waters due to the low chassis it sports. The reverse rate of the Ikv 103 is also quite good at 11 km/h. Even if this speed can't hold a candle to the regular speed the 103 has, the reverse rate is still enough to safely peek over hills and reverse back into cover before getting fired upon.

{{main|kan Ikv 103 (105 mm)}}

The Ikv 103 is outfitted with a 105 mm cannon firing heavy shells with a reload of 8 to 10 seconds depending on crew qualifications. This cannon is unusually short for its calibre, firing heavy shells with low-velocity. The gun is aimed manually without the help of electrical equipment, resulting in a slow traverse rate. At maximum, the gun traverses at 8° per second, resulting in many deaths at closer ranges. The stock gun accuracy is above average.

The gun has a significant recoil, which can mess with the aim in RB/SB and will slightly move the tank backwards. The recoil can also be used as an advantage to fly off the hill as fast as possible before an enemy started firing back.

Although the early psgr m/49 lacks significant amount of angled penetration and post-penetration damage, it works just fine at medium to long range. It can also be easily launched over cover at 450 m range while the SPG is fully concealed, which makes it useful in any situation. The later slpsgr m/65 HEATFS round packs up to 400 mm of flat penetration, generally penetrating anything it sees and making the post-penetration much deadlier than before. This later shell also features a higher velocity than the previous round, so it might actually hit moving targets.

Unfortunately, a lot of heavy tanks have near-impenetrable machine gun ports and even HEATFS will fail to get through them, so the gun cannot be fired entirely without care. If the {{PAGENAME}} is used as a backup along with the 7.0 lineup, it will often fail to penetrate or bounce off the turret of many US heavy tanks due to their sheer thickness.

This SPG uses X1.9-3.5 scope again unlike the [[Pvkv m/43 (1963)|Pvkv m/43]], so it's difficult for it to fight at long range.

This makes the gun most effective at medium ranges, where the traverse is ideal, and the shell velocity isn't crucial. It should be noted that the incredible gun depression allows the Ikv 103 to fire directly from extreme angles allowing it to suddenly engage targets in RB without the risk of overexposing the tank, something which becomes incredibly useful to increase the vehicles survivability.

==== Ammunition ====

* '''psgr m/49''', HEAT - This stock shell offers great penetration values and should give you no trouble penetrating the upper glacis of common enemies like the Panther and Pershing series tanks. Even heavy tanks such as the Tiger II will also be vulnerable to this shell. Though it does suffer from the usual characteristics of HEAT which is the low muzzle velocity and sensitive fuse.
* '''sgr m/34 LT''', HE - This shell is able to destroy some medium and heavy tanks in one hit by attacking their roof, but some heavy tanks in up-tier already have 26 mm RHA thick roofs, making them effectively invulnerable to it.
* '''slpsgr m/65''', HEATFS - The HEATFS shell is an upgrade compared to the regular HEAT shells. The penetration is most noticeably increased. It also has a slightly faster muzzle velocity, which is helpful for sniping. However the major downside is its cost. In most situations, the stock HEAT shell will suffice.
* '''rökgr m/49''', Smoke - The smoke shell will help blind enemies to allow you to move behind cover.

== Usage in battles ==


The Ikv 103 is a nimble vehicle with a small silhouette compared to its peers. The lightweight and powerful gun set it apart from other vehicles at the battle rating.

The general playstyle can be compared to the Jpz 4-5 found in the German tech tree, as the vehicle has to make use of positioning rather than frontal survivability. The Ikv 103 can't use common sniping locations effectively since any form of enemy retaliation will destroy the vehicle completely. Instead, the 103 needs to drive full speed to various locations where enemies are unlikely to expect danger. Although this playstyle requires a lot of map knowledge, the reward is quite high for a successful flank, thanks to the devastating cannon the Ikv 103 carries.

Thanks to the light vehicle weight and strong engine, the Ikv 103 is also able to climb a lot of obstacles, something that helps a lot when fighting on bad terrain. However, maps that lack terrain entirely cripple the 103's performance quite significantly, since the tank cannot hide, resulting in a lot of face-to-face engagements, which the Ikv 103 almost always lose.

In AB, when it's impossible to find a good hill or the enemy is just too good, one can use this SPG as a mortar to bombard enemy tanks at about 450 m range with HEAT straight out of cover. Any cover that completely covers the SPG will work at this point, whether it's a random rock or terrain. It's also technically possible to fire over shallow hills while standing on them at ranges of about 300 m, but this is not entirely safe and constantly leads to situations, in which {{PAGENAME}} is flanked or sniped. This playstyle works quite well over flat plains and some sniping hills, which are generally incapable of stopping shells with low velocity, but will likely block high-velocity APHE of all enemy tanks. Use binoculars to track enemy movements and to pre-aim. Be careful to not provoke other HEAT tanks into an artillery battle unless you are sure about your aim, as the {{PAGENAME}} won't survive even a single HE/HEAT hit.

=== Pros and cons ===


'''Pros:'''

* Excellent HEAT round for its rank, able to penetrate the upper glacis plate of the Tiger II
* Excellent upgraded HEATFS round, useful even way outside of tanks own rank (technically can penetrate [[T95]])
* Good speed, able to secure crucial positions or even flank the enemy
* Neutral steering
* Small silhouette, can completely hide behind medium tanks hull or cover
* Incredible gun depression
* Due to having a roof, will not be as interesting to fighters as previous SPG models (although it won't really save from them)
* Can work as artillery in AB, with not many tanks being able to do anything about it, but to ask for an air raid

'''Cons:'''

* Poor armour, counts as open-topped, sides able to be penetrated even by rifle-calibre bullets, especially behind the tracks - Ikv 103 must rely on stealth
* No MG to destroy light fences that can fuse the HEAT shells
* Will struggle through any obstacles due to its low mass
* Slow gun traverse, makes aiming in CQB or at a moving target harder
* Vehicle reverses slightly when firing, forcing you to reacquire range of target after every shot
* HEAT shell has a relatively low muzzle velocity, may be hard to fire accurately over long ranges
* HEATFS shell is expensive and should thus be used conservatively

== History ==


The [[Ikv 72|Infanterikanonvagn 72]] was a project started in 1949 by Sweden for an assault gun. The intended role of this vehicle was to support the infantry in the attack, replacing towed artillery guns. The design was to be small, and of light weight, around 6 tons. This was to reduce costs so a larger amount could be produced. The first prototype from Landsverk, completed in 1950, was armed only with three machine guns. This was insufficient, and it was re-armed with a 75 mm cannon, the same gun from the [[Strv m/42 EH|Strv m/42]]. It was a small, lightly armoured vehicle, with a casemate superstructure housing the 75 mm gun. It had a crew of 4, and it was open topped. Starting in 1956, the Ikv 72 was upgraded to the Ikv 102 standard. This upgrade added an armoured roof for the crew compartment and a 105 mm gun replaced the 75 mm gun. The Ikv 102, in turn, was upgraded to the Ikv 103 standard. The Ikv 103 featured an improved engine, the Volvo B42 engine. The air intake was moved to grills on the rear of the vehicle, instead of through the crew compartment.

=== [[wt:en/news/6600-development-ikv-103-heat-mortar-en|Devblog]] ===
In 1949, the procurement division of the Swedish army placed an order for the development of a light assault self-propelled gun to substitute the [[Sav m/43 (1946)|Sav m/43]] SPG. Three companies took on the work: AB Landsverk took on the development of the platform, Volvo was responsible for the powertrain, and Bofors for the armament. In fact, three versions of the vehicle for different purposes were planned at first: one with a 75 mm cannon, a machine-gun-equipped modification, and also a special one that was intended for the deployment of specific weaponry, such as flamethrowers and rocket launchers. Thus, a light (merely eight tonnes in all), tracked infantry-support vehicle was produced, with an open cabin and bulletproof armour.

In 1952, a cannon-equipped version, under the designation the Ikv 72 (short for "infanterikanonvagn", meaning "cannon-equipped infantry-support vehicle" in Swedish), was put into service. A little later, the SPGs were re-equipped with 105 mm howitzers and the cabin was retrofitted with a roof, which could protect the crew from bullets and shrapnel. This modification received the designation Ikv 102. Meanwhile, the Swedish army ordered another series of the vehicle with an upgraded chassis to allow installation of a new air-cooled engine, while the gun and the armour remained the same as the Ikv 102's. This new version was designated Ikv 103. The Ikv 102 and 103 SPGs remained in use by the Swedish army until the mid-1970s, when they were replaced with the [[Ikv 91]] SPG.

== Usage in battles ==


As the BM-8-24 lacks survivability, only carries 24 rockets which have poor penetration, and has average mobility, the ideal playstyle is to use terrain or buildings to hide and wait for enemies to pass, only engaging if it's a target you can penetrate and waiting until its side or rear is to you.

The BM-8-24 has extremely poor survivability, as it only has two crew, armour which can only stop MG fire, and exposed rockets on the rack. The ammo is extremely easy to detonate with a direct hit, with chemical rounds only taking one shot to do so and kinetic rounds taking two or three depending on caliber, and even machine gun fire is able to set them off if enough rounds hit a single rocket .

Despite the respectable HE filler, the 9mm of penetration leaves your list of viable targets is extremely limited, with only open vehicles and enclosed vehicles with the thinnest of armor being vulnerable to your rockets. Even vehicles with poor armor such as the Panzer II, BT-5 and 7, or M3 Stuart may be difficult or impossible to kill. Some vehicles such as the LVT have thin enough armor for a shot anywhere to be able to kill, while others such as the M2A4 or Panzer 38(t) may only take damage from a rocket hitting the roof, cupola, or hull roof. Luckily, the rockets have enough HE filler to guarantee a kill on a hit with an open top vehicle, or on penetration of an armored vehicle (with the exception of some larger vehicles such as the LVT due to the distance between the crew). It is also theoretically possible to kill tanks with overpressure by hitting the ground under them, however this may be difficult to do consistently, especially given the poor depression of the rocket rack.

Due to the difficulty of accurately aiming the rockets past close range, the ideal scenario would be to hide behind cover that's nearby the enemy and that you can see over/around with your camera, allowing you to watch over it for viable targets, peeking out once you spot one. Since some vehicles require roof shots to kill, it may be advantageous to be above your target, although the poor depression of the rocket rack means to aim downward enough you'd have to be on a slope. It may also be viable to use spots that require engaging at longer ranges and only firing at open/light vehicles that don't require aiming for weak spots, especially as the drop of the rockets allows for arcing them over hills while you safely sit behind them, which is by far the safest way to use this vehicle due to peeking even just your rocket rack over cover leaving your ammo open to being detonated.

=== Pros and cons ===


'''Pros:'''

* Rocket launcher vehicle
* Smallest rocket launcher profile
* High-velocity rockets (good for medium-long range)
* High firerate
* Small and agile, allows for quick re-positioning on the battlefield

'''Cons:'''

* No other armaments except rocket launchers
* Rockets only have 13 degrees of horizontal guidance in each direction
* Same poor armour as the [[T-60]]
* Reloads the entire rack at once, leaving you helpless for the entire 30 second reload if you're out of ammo, and doesn't reload any faster if you don't need a full reload
* Small rocket supply of only 24
* Very poor depression can cause it to be problematic to hit low targets at close ranges
* Lowest penetration on a primary weapon in the entire game; penetration is extremely poor even on direct hits, leaving most vehicles difficult or impossible to penetrate
* Very wide rocket rack causes strong parallax that changes with each shot, making accurate aiming harder

== History ==

===Development===
The concept of a multiple rocket launcher system came about in June 1938, when the Soviet Jet Propulsion Research Institute was authorized by the Main Artillery Directorate to develop such system for the RS-132 rocket in use on their aircraft. A prototype by I. Gvay in Chelyabinsk was tried and fired M-132 rockets on ZiS-5 trucks, though these were unstable and were revised on the proposals of V.N. Galkovskiy to mount the launching rails longitudinally. Testing for the newly made prototype began at the end of 1938, firing 233 rounds in a couple of salvos. The rockets were found to be able to hit up to 5,500 m out, but the system was not looked fondly upon by the artillery branch. It took 50 minutes to load 24 rockets onto the launching rail, while a regular artillery cannon and howitzer can fire about a hundred in the same time at a sustained rate.

Testing continued up until 1940 and with a prototype of a truck with the launch rails on the back. The design was approved for production before Germany invaded the Soviet Union in June 1941, and mass-production began after the first month of the war, where the multiple rocket launchers proved very successful. During the war, the launchers were taken with much secrecy and operated by specialized troops such as the NKVD who do not even know its true name. Through the presence of a "K" on the vehicles from the Komintern Factory, the soldiers operating decided to nickname these launchers ''"Katyusha"'' after a popular wartime song of the same name. Up to 3,237 of all types of Katyusha launchers were produced from 1941 to the end of 1942, and more than 10,000 were made by the end of the war.

===Advantages and disadvantages===
Compared to the contemporary artillery systems of the time, the multiple rocket launcher system presented a different kind of artillery barrages used in the field. Advantages the multiple rocket launcher was that they were simple, extremely effective in saturation bombardment, fires lots of ordnance in a small time span, and were usually attached to mobile vehicles that can permit a quick retreat after firing to prevent counter-battery firing. Disadvantages with the system were that the rockets took a long time to reload, less accurate than regular artillery guns, and cannot sustain fire for a long period of time. However, in the battlefield, the multiple rocket launcher induces a greater psychological effect onto the targets on the receiving end due to the heavy amount of explosives able to be delivered in a short time. A battery of only four launchers could deliver their salvos of about 4.35 tons of explosives in a span of no longer than 10 seconds at a 400,000 square metre area.

===Designations===
Multiple variants of the multiple rocket launcher systems were made in the course of the war as the design is simply the attachment of launch rails onto a variety of vehicles. Each vehicle has different names that follow a template to distinguish their types.

* "BM-x-y" indicates a ground vehicle.
* "M-x-y" indicates a towed variant.
* "y-M-x" indicates a naval variant.

and "x" stands for the missile model while "y" stands for the number of launch rails available for the launcher variant. For example, the BM-8-16 indicates a ground vehicle firing M-8 rockets with 16 rails available to mount on.

Vehicles using the Katyusha launchers range from trucks, cars, and tanks. The production started with trucks such as the ZiS-6, then moving on to STZ-5 artillery tractors, then on Allied Lend-Lease vehicles. The 82 mm M-8 rockets, which saw service in August 1941, was the most popular rocket variant and saw use on the trucks and even tanks, which would make the '''BM-8-24''' rocket launcher tank mounted on the [[T-60]] light tank. Another attempt with tank mounting was with a [[KV-1 (L-11)|KV-1]] heavy tank as the ''KV-1K'', but as a waste of heavy armour, this was scrapped.

===Combat usage===
The Katyusha rocket launchers first saw service during the opening of Operation Barbarossa against Germany. On July 14, 1941, under the experimental battery commanded by Captain Ivan Flyorov, seven launchers were used in Rudnya and were able to cause massive destruction to the Germans in the town before they fled in panic. This success prompted the Red Army to build up more Katyushas in their inventory and raise more batteries and regiments for the vehicle. All these units were under NKVD control for secrecy until the Germans reveal their own multiple rocket launcher systems, the Nebelwerfer. The Germans nicknamed the Katyusha launchers as the ''"Stalin's Organ"'' after Joseph Stalin and how the launchers are organized in a way to look like a church organ. This German nickname became widely known in other areas in Western Europe. By the end of 1941, eight regiments and 37 independent battalions were available with a count of 554 Katyushas total.

The rocket launchers continue to become more integrated into the rest of the army as the war continued. Heavy mortar battalions were armed with the newer M-30 rocket launchers with heavy 300 mm M-30 rockets on June 1942. In July, a battalion of rocket launchers was added into the tank corps. The organization and equipment of these mortar battalions equipped with the Katyusha continue to increase and by the end of the war in 57 regiments, about 518 batteries of Katyusha launchers were available.

===Legacy===
The Katyusha launchers, issued in large numbers in the Eastern Front, was largely successful in the strategic effect of the war, granting the Soviet Union the ability to lay down a very heavy and shocking bombardment very quickly. The success of the system prompted many other countries to pursue such a system as well, such as the modified [[Calliope|T34 Calliope]] based off the Sherman and the Germans [[15 cm Pz.W.42|Panzerwerfer 42]]s. Today, the multiple rocket launcher system is still widespread with the implementation of newer technology, rockets, and missiles that make the rocket launcher system a very potent weapon to anyone on the receiving end.

Based on the T-60 light tank, the first BM-8-24-class self-propelled mount featuring a jet-based volley-fire system on a tank chassis was built in 1941. At first the self-propelled mount was released on the basis of the T-40 light tank, but it was later replaced on the assembly line by the T-60 tank, and production continued on this basis.

The jet-based artillery subdivision of which the BM-8-24 MRLS SPG was a member was subordinate to Supreme Command. Jet-based artillery divisions were assigned to divisions and added to long-range (LR) divisions.

A total of 44 T-40 tanks were re-equipped as volley-fire installations.

== Description ==

The '''{{Specs|name}}''' (shortened as just '''{{Specs|pseudonym}}''', also nicknamed "Quadruplo") is a rank {{Specs|rank}} Italian self-propelled anti-aircraft gun {{Battle-rating}}. It was introduced in [[Update 1.85 "Supersonic"]].

=== Survivability and armour ===

'''Armour type:'''

* Rolled homogeneous armour (hull, turret, turret frame)

'''Notes:'''

* Suspension wheels are 15 mm thick while tracks are 20 mm thick and bogies 10 mm thick.
* The belly is 14 mm thick and mudguards are 4 mm thick.
* The turret is reinforced with a 10 mm thick framing supporting the quadruple gun mount.
* The hull-mounted MG has been removed and the port has been obturated.

The {{PAGENAME}} is based off the M15/42 hull, with an opened top turret surrounding the crew members. The gunner does have an exposed spot in the front, and if shown to the enemy, can be machine-gunned easily without them to have to fire their main cannon. The turret may protect you from small rifle-calibre bullets, but .50 calibre and up, especially on the M4 Sherman will be able to penetrate your turret from anywhere, as it is generally weak against them. The hull armour is decent, still keeping the armour from the M15/42 hull, but don't expect to tank a lot of shots, as most of your enemies will have better calibre weapons, mostly encountering 75 mm and Russian 76.2 mm cannons. You may be able to bounce some smaller calibre shells like the 37 mm cannons but don't rely on your hull armour as your turret will most likely be targeted by the enemy. You have a small crew count of 3 members, and with two in the turret, and having okay armour, you'll usually die in one hit.

== Usage in battles ==

In Realistic battles, the Quadruplo is best used in the support role when tank hunting, sticking with teammates, assisting them and potentially distracting the enemy. Your best bet of killing any tank, usually a Sherman, Cromwell or T-34, is from the side as the HVAP will pierce through their side armour, killing the tank. Light tanks such as M24s, Stuarts and Crusaders are able to be penetrated from the front, but usually this is only in close range engagements. T-50 and other slightly armoured light tanks will be tougher to kill, but you're still able to flank them. You can kill basically any SPAA you see, as you'll usually encounter trucks or armoured cars. Ambush and surprise tactics are good options to kill tanks effectively, as the enemy will stroll past you, usually showing their side armour. Aggressive playstyles are suggested to get the most out of the Quadruplo, similar to playing a Wirbelwind when tank hunting. Try not to expose yourself too much and move from cover to cover, as one hit from a tank shell, usually APHE, will knock you out in one shot, or the machine guns pierce your turret armour and kill both your gunner and commander. When it comes to shooting down planes in the Quadruplo, it is best to get their attention so they try to strafe you, or surprise them as they come closer to you, when you have a good shot as they won't have enough reaction time to evade your shots if they connect. Be mindful that you are open-topped, and you're less likely to survive a strafe run. It should also be noted that shooting continuously will sway the hull back and forth, which will make your aim go up and down.

=== Pros and cons ===


'''Pros:'''

* PzGr 40 shells are great at penetrating tanks from the sides and knocking out modules
* High mobility when spaded
* Great armour for a SPAA
* Guns have a very high rate of fire
* Ammo is stored in one belt, meaning you can continuously fire unlike the Wirbelwind
* Guns are placed very close together

'''Cons:'''

* Low reverse speed
* HVAP-T PzGr 40 belt is a tier IV modification
* Performance is inadequate when stock
* Gap in the gunner's position of the turret armour
* Turret can be penetrated by .50 cal machine guns
* 2 of 3 crew members crammed inside the turret
* Hull rocks back and forth when firing causing some rounds to miss
* Low ammunition count compared to its high rate of fire
* The ammo being stored as a single belt means that you have to completely empty it to reload

== History ==

{{main|M15/42#History|l1=History of the M15/42}}

The history of the M42 Contraereo began during the late stages of the Second World War. In the years following 1942, the Royal Italian army would set out a request for a mobile platform which could mount a special anti-air mount to bolster and provide protection to Italian mechanised columns. At the time they would be subject to very frequent air raids by the British RAF. Although they had some anti-air coverage, it was not enough for their needs. Ground units only really widely access to single 20 mm mounts, usually installed on armoured trucks.

To save time and to reduce maintenance costs, the Italian army opted to go with the M15/42 tank to be used as the basis for the SPAA platform. The original turret would be removed and completely replaced with a new polygonal welded open turret, containing quadruple 20 mm Scotti Isotta Fraschini anti-air cannons. The turret could accommodate belt-fed munitions or clip-fed munitions. At the time this was actually one of the better anti-air vehicles made, not many countries had something remotely comparable, but it would not be long until the Germans had gained a particular interest in the vehicle which would play later on. The first prototype of the M42 Contraereo would be completed by January or February 1943, it would then also be presented for trials at the "Centro Studi Motorizzazione dell'esercito" (in English: "Center for motorization of the army").

In terms of mobility, the M42 kept pretty much all the previous stats of the M15/42 tank, meaning it could reach speeds of up to 40 km/h. When it came to survivability, it also kept the same protection values as the previous M15/42 tank it was based of, however it is good to note that the removal of the 2 x Breda 38 machine guns that previously would be installed in the hull, would instead be covered by a 42 mm armour plate. The new anti-air turret was for the most part exposed to incoming enemy fire, and did not offer adequate protection levels.

As development of this anti-air platform continued, it's likely that a handful of prototypes were made. What ceased the further development of the vehicle however was the 8th of September Armistice of Cassibile. During the confusion of leadership in Italy, the Germans would use that as an advantage to invade the north of Italy and set up a puppet state lead by Mussolini. Due to this, the Germans took over any production factories, any vehicle development and would integrate it into the German army. In this case, at least one unit of the M42 Contraereo was captured by the German army and was likely thoroughly examined by German engineers.

Strv m/42 DT

U62038390: Updated ammo racks and added details about ammo racks and reloading to the pros/cons and usage in battles

{{Specs-Card
|code=sw_strv_m42_delat_torn
|images={{Specs-Card-Image|GarageImage_Delat_Torn.jpg}}
}}

== Description ==

The '''{{Specs|name}}''' is a rank {{Specs|rank}} Swedish medium tank {{Battle-rating}}. It was introduced in [[Update 1.97 "Viking Fury"]]. It is a development of the [[Strv m/42 EH|Strv m/42]] medium tank.

== General info ==
=== Survivability and armour ===
{{Specs-Tank-Armour}}

The hull of the Strv m/42 DT is identical to that of its predecessor, the [[Strv m/42 EH]]. While decent for its BR on the earlier tank, the hull armour is no longer good against the bigger guns that the Strv m/42 DT faces.

However, the Strv m/42 DT also sports a new turret to house the more powerful gun. The turret front is 60 mm thick, and the right side and area around the main gun is an angled flat plate. While not very thick, it is capable of ricocheting some rounds if the effective angle is increased using the excellent gun depression of the Strv m/42 DT. The left side housing the machine gun is rounded and is a weakspot when hull-down.

It is important to note that the turret has an open rear that exposes the crew to machine gun fire and shrapnel. It is also a considerably bigger target than the Strv m/42's turret. Most importantly, the gun autoloader is poking out of the turret and can be easily damaged by any aircraft, which is arguably even worse than losing a crew member.

Close artillery misses won't destroy this tank, but any direct hit to the turret's roof will penetrate and decimate the entire crew. HEAT hits on the turret front won't result in overpressure damage.

'''Notes:''' 


=== Mobility ===
{{Specs-Tank-Mobility}}


{{tankMobility|abMinHp=635|rbMinHp=363}}

Unsurprisingly, the mobility of the Strv m/42 DT is very similar to that of the Strv m/42. It can reach a respectable top speed and will usually be able to keep up with most advances, but suffers from a low reverse speed of about 5 km/h that makes it harder to back up from hull-down positions or into cover.

=== Modifications and economy ===
{{Specs-Economy}}

== Armaments ==
{{Specs-Tank-Armaments}}
=== Main armament ===
{{Specs-Tank-Weapon|1}}

{{main|pvkan m/43 (75 mm)}}

The Strv m/42 DT is armed with the same 7,5 cm pvkan m/43 used by the [[Pvkv m/43 (1946)|Pvkv m/43]] tank destroyer. However, on the Strv m/42 DT, the gun is fed by a special semi-automatic loader with a four-round clip (similar to the Japanese [[Chi-Ri II|Chi-Ri]] medium tank), allowing for a fast five-round burst (including one pre-loaded in the gun barrel) after which the gun must be reloaded manually.

With the autoloader, the reload takes from 3.9 to 3 seconds, which otherwise would take around 8-6 seconds. This allows the tank to swap between kinetic and HE shells on the fly and to sometimes reload before enemy drives out of cover to retaliate.

As is usual for Swedish vehicles, the turret provides for decent gun depression an -10° , though gun elevation is limited to only +12°, which stops the tank from fighting when charging down or along the side of a hill. The gun stabilizes rather quickly as long as the targeting skill of the crew is maxed out and tank isn't driving over rough terrain.

On a capture point, each spent shell is restocked in about 5.5 seconds. This is important to keep in mind, as the semi-auto loader rearms extremely slowly, forcing the tank to not fire for 25 seconds after the last shot for the first shell to be loaded and another 18 for each next one. Restocking the autoloader magazine on a capture point circumvents this and reloads the autoloader faster, which might allow to repel more tanks than normal.

Note that the gun breech is rather large and takes up a lot of room in the turret, thus a turret penetration is likely to also result in a damaged breech.

==== Ammunition ====
{{:pvkan m/43 (75 mm)/Ammunition|slpprj m/41, sgr m/38, slpgr m/43}}

The Strv m/42 DT starts with the rather underwhelming stock '''slpprj m/41''' uncapped AP shot, which has no explosive filler. However, at Rank IV the excellent '''slpgr m/43''' APCBC shell becomes available. Not only does it ricochet less than the stock AP, has a higher muzzle velocity, and has better penetration, it also has a lethal 110 g TNT filler that is devastating when it penetrates.

The penetration of kinetic shells is not very good for a tank of this BR, but the Strv m/42 DT is quite tall and at close to medium range it can negate enemy angled armour with that alone.

The '''sgr m/38''' is not to be ignored, as there are a lot of open-topped SPG at the rank, which are difficult to take out with kinetic ammunition, but will definitely fail to reload before HE is fired at them, should they survive the first shot.

'''Notes''':

* The first-stage ammo racks provide the vehicle with a faster reload but has a small capacity (4 rounds), however the vehicle is also capable of reloading the main gun directly from the other ammo racks.
* The turret can never be fully empty without depleting the first-stage racks, and the hull can only be empty if you take 5 or less shells

=== Machine guns ===
{{Specs-Tank-Weapon|2}}

{{main|ksp m/36 (8 mm)}}

The {{PAGENAME}} has a standard 8 mm coaxial machine gun. While it is slightly bigger in calibre than 7.62 or 7.7 mm MGs met on comparable vehicles, the machine gun lacks penetration power to damage most opponents. Nevertheless the ksp m/36 machine gun can be used against open-topped vehicles. Furthermore, it also has an additional 13 degrees of elevation which can prove useful in engaging enemy planes.

== Usage in battles ==


The Strv m/42 DT's standout feature is an excellent reload rate, which can be as low as 3 seconds. To complement this gun, the Strv m/42 DT is equipped with a stock AP round, and an APCBC shell which has reasonable penetration and explosive filler values compared to similarly-sized rounds at this tier. At its best, the gun will easily blast most medium and light tanks, but will struggle with the heavy tanks, so choose your fights accordingly.

This vehicle is not especially well-armoured. It can often withstand one or two hits, but any more and it will usually be destroyed. Taking high ammunition loads further hampers the tank's survivability, as it makes the chance of an ammunition detonation significant. Additionally, the ammo racks in the front of the hull will almost always have ammo in them, and while they're in a position unlikely to be shot from the front, a shot to the front of the hull from the side can result in an ammo detonation. From the side, a weak armour setup means that autocannons on many anti-air vehicles can penetrate and deal massive damage to internal components. This means, that tank commanders might want to rely on teamwork, much like with the [[Pvkv II]], as either teammates take the hit and leave the enemy exposed to at least two counter shots, or finish the job while the {{PAGENAME}} repairs or disables something else. Either way, with armour this thin, it is necessary to pay attention to enemy flankers.

The Strv m/42 DT's hull is taken from the earlier [[Strv m/42 EH]], and thanks to an improved engine, is above-average in terms of mobility. When stock, mobility can be sub-par, but once mobility modules have been researched, the tank becomes quite capable in this department. With this level of mobility, it can acquire ambush positions or act as a viable flanker. (In such situations, the gun's quick reload makes itself very useful; the Strv m/42 DT is able to destroy multiple unsuspecting enemies in quick succession.) One thing to note is that this tank has a poor reverse speed, which can make peeking and firing from behind ridgelines dangerous.

In hull-down positions, this vehicle can use its great gun depression to effectively fire at enemies from behind cover, but it's best to avoid exploiting it to try and fight over high hills, as it's not as great as on the SPGs and tanks before it.

=== Pros and cons ===


'''Pros:'''

* Excellent reload rate allows to fire twice per normal enemy reload
** Ammunition reload on a capture point loads into the ready-rack almost as fast as the firerate, allowing for consistent rapid fire
* Decent gun depression
* Mobile enough to flank when spaded
* Still has a reasonable fire rate when first-stage rack runs out

'''Cons:'''

* Poor stock uncapped AP shot with no explosive filler, and the APHE starts to become inadequate when fighting head-on in uptier
* Very long ready-rack reload, unless on a capture point
* Narrow tracks reduce off-road mobility
* Poor reverse speed will let most tanks to fire back before it can retreat
* Lightly armoured
* Poor ammo rack configuration
* Large and visible profile
* Gun loader and breech can be easily destroyed by an airstrike

== History ==


In 1944, the Swedish military considered upgunning the [[Strv m/42 EH|Strv m/42]]. They designed a new turret with a new 75 mm gun with an autoloader. The turret was named "Delat Torn", which means "split turret" in English. This name comes from the fact that the autoloader would split the turret down the middle into two separate compartments. The gun was set as far back as possible inside the turret in order to reduce how much of the barrel hung out of the turret. In 1944, a mockup was made, with a wooden turret. The prototype was made in 1945, and it was tested throughout 1946. It was found that the design was unsuccessful, and it never entered production or service.

== Description ==

The '''{{Specs|name}}''' is a rank {{Specs|rank}} Soviet light tank {{Battle-rating}}. It was introduced during the Closed Beta Test for Ground Forces before Update 1.41. One of the less appealing Soviet vehicle due to its weaponry and layout, it can still perform well if utilised correctly and its faults are accounted for.

=== Survivability and armour ===
{{Specs-Tank-Armour}}

[[File:T60 Screenshot 3.jpg|thumb|T-60 on "[[Frozen Pass (Ground Forces)|Frozen Pass]]"]]
The armour of the T-60 is fairly effective frontally, being for the most part angled gives it good protection against similarly rated opponents with a high chance of causing shots to ricochet, however a shot to the side will likely be fatal due to the thin (15 mm) side armour and the vehicle only having a 2 man crew, this means that the loss of 1 crew member will cause the vehicle to be knocked out.

{{tankMobility|abMinHp=118|rbMinHp=67}}

The mobility of the T-60 is very comparable to the T-26, while it is fast enough to move around the map with ease, it is not mobile enough to be the first friendly to the cap or camping position, the mobility is enough to allow for a support or flanking role in most situations.

{{main|TNSh (20 mm)}}

The main armament of the T-60 is a 20 mm TNSh cannon, this has a fire rate of 750 rounds/min and will have to reload after 58 rounds have been fired, the gun is certainly effective against lightly armoured opponents but will have trouble against higher-rated heavy and medium tanks.

== Usage in battles ==

[[File:T-60 Screenshot 1.jpg|thumb|T-60 driving through "[[Eastern Europe (Ground Forces)|Eastern Europe]]" ]]
The T-60 is a fine little tank that excels in very particular situations; namely holding corners, flanking, and acting as a close range SPAA. This tank should never be used for long-range shooting or in pushes against an enemy head-on, one should always try to use its speed and manoeuvrability to gain an advantage before attacking. In a [[:Category:Anti-aircraft vehicles|SPAA]] role, the long reload time for this tank's main weapon can be a severe disadvantage. This means that one should use controlled bursts when attacking aeroplanes, making all shots count, and only picking large slow moving targets when at the range. The presence of a co-axial machine gun, however, not only adds to the firing density but allows for the tank to fire whilst the cannon is reloading. This machine gun has no utility against armoured targets. In this role, the T-60 is the only SPAA in this rank that does not have to fear 7.7 mm rounds (although 12.7 mm rounds can be very deadly - the [[M2A2]] is a very dangerous opponent, for instance). This means that T-60 pilots can be confident that they can survive being strafed by most fighter aircraft. In RB this tank serves as a perfectly capable replacement for the [[GAZ-AAA (4M)|4M GAZ-AAA]]. In conclusion, the T-60 is a versatile tank of good effectiveness that is a constant presence of any Rank I ground forces game. Its gun gives it easy penetration at the sides and some fronts of low-rank tanks.

This is a very versatile tank and that is its greatest strength. Its greatest weakness is it's horrible all around armour, always remember that you will probably not survive a single hit from an AT gun, and as such stay hidden and behind cover. In order to accomplish this use, this tanks great manoeuvrability to your advantage and try to hug cover and move in depressions of the landscape. When using this tank always attack from an unexpected angle then shot your entire belt and afterwards '''always re-position after an attack'''. A great strength of this tank is that at any point it can go from flanking an enemy tank to acting as a front line SPAA, and in many games this amazing ability that can save you and your comrades from certain death at the hands of an enemy bomber or attack plane.

=== Pros and cons ===


'''Pros:'''

* Sloped frontal armour
* Fast-firing gun, that can even harm aircraft due to calibre and rate of fire
* Good manoeuvrability
* Belts have a high ammunition count per belt
* Can act as a decent front line SPAA
* Low profile
* Often not regarded as a high priority target[[File:T-60 Screenshot 4.jpg|thumb|T-60 driving into "[[Eastern Europe (Ground Forces)|Eastern Europe]]"]]

'''Cons:'''

* Poor armour
* Very cramped interior
* Only 2 crew so you can't lose anyone
* Long reload time
* Very slow at climbing hills
* Retains speed bad
* Poor penetration values
* Poor post-penetration damage

== History ==

===Development===
In 1938, a task to create an amphibious and non-amphibious scout tank was given to Nicholas Astrov's design team at Moscow Factory No. 37. The result was the T-30A and T-30B prototypes, with the A model being amphibious. The T-30A went on to become the T-40 amphibious scout tank, while the T-30B went on to become the '''T-60''' scout tank. Production started on July 1941, one month after the German invasion in Operation Barbarossa.

Originally with a 12.7 mm machine gun, the T-60 was up-gunned with a 20 mm TNSh cannon, which was derived from an aircraft cannon. The gun could penetrate 15 mm of armour at a 500 meters range, which proved very inadequate against the Germans [[Pz.III F|Panzer IIIs]] and [[Pz.IV F1|Panzer IVs]], which had a maximum of 50 mm of armour on the front. Not only that, the scout tank had poor mobility on cross-country terrain and had a maximum armour of only 20 mm thick. Despite that, the T-60 was easily produced and 6,292 of these tanks were produced between 1941 and 1942.

===Usage===
The low gun performance urged for an attempt to upgrade the tank with a 37 mm ZIS-19 cannon or the standard 45mm tank gun. Both of these projects were proven impossible. The T-60 served as a light tank up until the better [[T-70]] light tank was chosen as the new standard Soviet light tank in 1942, which had better armour and gun.

The T-60 went on in armour developmental projects for the Soviet forces, such as the designing of the T-90 anti-aircraft vehicle. But perhaps the most unique project that it played in was the ''Antonov A-40'', which was the Soviet's attempt on a "flying tank". The A-40 was a glider design that has wings attached to a lightened T-60 (removing its armament, ammunition, some accessories, and most of the fuel). On September 2, 1942, in a test, the prototype was towed by a [[TB-3M-17-32|TB-3 Bomber]] into the air. When released, the A-40 reportedly glided smoothly on its descent, despite the drag it put on the TB-3 plane. The A-40 landed safely and was able to drive back to the testing site after detaching the wings. The project was then abandoned due to the lack of enough aircraft with the power to tow the A-40 at 160 kilometres per hour speed.

The T-60 also were used by the Romanians when they captured 34 of them and modified them into the TACAM T-60 and Mareşal M05, both tank destroyers. All examples of these vehicles were confiscated by the Soviets after Romania switched to the Allies.

=== In-game description ===
The T-60 light tank was developed in August, 1941 at Moscow Factory #37 under the management of N.A. Astrov. In September, 1941 the T-60 was accepted into the arsenal of the Red Army and was released serially in several automobile factories. The T-60 was produced until February, 1943, when it was replaced on assembly lines by the more powerful T-70 light tank. A total of 5,920 T-60s were produced, 1,366 of them in 1941. Most of them were built at the Gorky Factory.

Large numbers of T-60 tanks were used in battles from 1941 to 1943, starting with the Battle of Moscow and ending with the elimination of the Leningrad blockade in January, 1944. The T-60 was used actively throughout the Battle of Stalingrad and the Kharkov Operation. Due to significant losses, the T-60 was gradually removed from the front lines in late 1942.

The 90 mm M3 is the same gun available for the Super Hellcat, the T25 or the M26 and stays reliably accurate until 800 m distance. Beyond 1,000 m the loss of accuracy becomes a real handicap. The high muzzle velocity of your shells grants you pretty flat firing trajectories and thus helps fire at moving targets from a distance. In that regard, using the "sight distance control" feature can increase your chances of successfully hitting enemy tanks.

The rotation speed of the gun is better than average compared to other tanks at the same rank or battle rating. Which makes tracking a target from a distance an easy task to perform as your targeting process is fast. Elevation and depression angles of the gun are important, allowing you to fire from unusual positions (behind a ridge, from uphill, etc.). Your reload time is similar to vehicles at the same BR, if not a little longer than average. Your recoil is important but not powerful enough to throw your gun off target after firing. Lacking a stabilizer, the tank can't reliably fire on the move.

==== Ammunition ====
The available ammunition allows for engaging all types of targets:

* '''T33''': APBC; a solid shot with an average penetration power and no explosive filler.
* '''M71''': HE; useful for destroying open and lightly armoured vehicles.
* '''M304''': APCR; a composite round with a very high penetration power but no explosive filler and will only penetrate flat vertical surfaces.
* '''M82''': APCBC; a capped armour-piercing shell with a ballistic cap that has a better but still average penetration power and an explosive filler. It will destroy any armoured target it penetrates.
* '''M348''': HEATFS; a HEAT round with very high penetration and excellent performance on angled armor
* '''M313''': Smoke; useful to blind enemy vehicles that are too remote for you to disable so that you can progress towards objectives.

The {{PAGENAME}} has the same good protection as the 105/25 M43: thick vertical front armour plate, reinforced sides and a crew sitting apart in a widened hull. The {{PAGENAME}} also gets an additional 25 mm spaced armour plate on the front and the sides of the casemate, increasing the vehicle's protection against chemical rounds and bringing its frontal armour to 100 mm. However, the poor roof armour and a crew of only 3 are still weak points. Your front plate is also wide and easy to target.

Notes:

* Shells are modeled individually and disappear after having been shot or loaded.

== Usage in battles ==


;Combat tactics

The {{PAGENAME}} is best when used as a tank destroyer thanks to its good frontal armour and the good penetration of its rounds, provided you stay at a distance guaranteeing your survivability (800-1,000 m). With a maximum penetration of 64 mm at 1,000 m for the APCBC round and 100 mm for the HEAT shell, the vehicle will have no problem penetrating the armour of most enemy vehicles at the BR.

If you play too close to the frontline, most tanks will be capable of disabling you. Your weak sides will be exposed if you are taken in a pincer move and being immobilized with the enemy close to your position pretty much seals your vehicle's fate.

;Notable enemies:

* Tank destroyers with long guns that can penetrate from long range like the [[M10 (Family)|M10]], the Marder III, the Sd.Kfz.234/4, the StuG III F, the SU-57B, the ASU-57, the YaG-10 (29-K), the Gun Carrier (3-in), the Archer, the Na-To, the 90/53 M41M or the Pvkv II.
* Tanks with powerful HEAT shells like the M4A3 (105), the StuH 42 G, the 105/25 M43 or the Sav m/43 (1946),
* Heavily armoured tanks that can shrug your shells off like the MK-II "Matilda" (USSR), the KV-1 (L-11), the Churchill I or the Matilda III,
* Frontline tanks with sloped armour like the M4, the M4A1, the [[T-34 (Family)|T-34]], the Sherman II, the M4A4 or the ARL-44 (ACL-1),
* Fast and agile light tanks such as the [[M24 (Family)|M24]], that can easily flank the Semovente undetected are dangerous threats. Their speed and small size make them difficult to target for the Semovente's gun and they can disable you easily at close range.

;How to defeat a {{PAGENAME}}

* Avoid any frontal encounter. Flank it and aim for the sides of the casemate.
* Wait for it to have shot and be reloading (it gives you at least 6 seconds to act).
* If you're forced to engage the Semovente frontally, be as close as possible to increase your chances to penetrate. Additionally, if you're using HEAT rounds, unless you have 130+ mm of penetration, avoid shooting the main front plate as against chemical shells as it has 120-130 mm effective protection
* If you can't disable it in one shot, immobilizing the {{PAGENAME}} buys you time to finish it off. Either shoot the transmission, the driver or the engine to do so. Stay out or get out of its line of fire once it is immobilized.
* When flying an aircraft, target the crew compartment to knock the crew out or the engine bay to immobilize it.

=== Pros and cons ===


'''Pros:'''

* Effective frontal armour and all-around protection
* Small frontal profile makes the tank easy to conceal and difficult to hit
* Decent mobility and good hull traverse
* Has access to HEAT rounds

'''Cons:'''

* Armour becomes much less effective when uptiered against stronger vehicles
* As a casemate tank destroyer, the Semovente is extremely vulnerable to flanks
* A cramped interior and only 3 crew lessens survivability
* Inadequate gun for its tier

== History ==

{{main|105/25_M43#History|l1=History of the 105/25 M43}}

;Development

After the Italian Armistice in 1943, the Germans took control of Northern Italy and restarted the production of the Semovente da 105/25. Lacking 105 mm guns, 53 units were produced with the 75/34 Mod. SF gun for the Wehrmacht in 1943-44.

;Combat usage

These saw service with German forces in southern Europe in 1944.

Notes:

== Usage in battles ==


The BM-8-24 only offers 24 rockets as it's main armament, the ideal playstyle is use the terrain to hide from the enemies and wait for them to pass you by before you strike. The rockets work best when they are fired in volley, it takes one well placed hit to knock out an enemy tank.

To do this, get close as you can and aim for the sides, you want to aim for biggest surface you can see. The rockets are not accurate as with any rocket tank, so aiming for sides offer your biggest chance to successfully hit the target. You only need one hit to penetrate and detonate inside of the enemy tank knocking it and awarding you the credit for it.

The BM-8-24 is weak, a single HE or APCBC round, in simple terms any round with HE filler which hits the ammo rack which contains all 24 rockets will see the tank explode, like a firework. Even shrapnel or machine gun fire hitting the rockets will destroy them, they may not detonate with some machine gun hits but the rocket will be destroyed, reducing the effective amount.

=== Pros and cons ===


'''Pros:'''

* Rocket launcher vehicle
* Smallest rocket launcher profile
* High-velocity rockets (good for medium-long range)
* Small and agile, allows for quick re-positioning on the battlefield

'''Cons:'''

* No other armaments except rocket launchers
* Rockets can only face forwards
* Armour of a [[T-60]] (very low)
* Extremely long reload time, even with maximum reload rate it still takes 3.2 minutes to reload all rockets
* Small rocket supply of only 24
* Very poor depression can cause it to be problematic to hit low targets at close ranges
* Limited penetration of rockets even on direct hits, being only able to damage open SPG's and SPAA's
* Non-adjustable gun sights, aiming is almost pure guesswork (though can be fixed by setting up a custom sight)

== History ==

===Development===
The concept of a multiple rocket launcher system came about in June 1938, when the Soviet Jet Propulsion Research Institute was authorized by the Main Artillery Directorate to develop such system for the RS-132 rocket in use on their aircraft. A prototype by I. Gvay in Chelyabinsk was tried and fired M-132 rockets on ZiS-5 trucks, though these were unstable and were revised on the proposals of V.N. Galkovskiy to mount the launching rails longitudinally. Testing for the newly made prototype began at the end of 1938, firing 233 rounds in a couple of salvos. The rockets were found to be able to hit up to 5,500 meters out, but the system was not looked fondly upon by the artillery branch. It took 50 minutes to load 24 rockets onto the launching rail, while a regular artillery cannon and howitzer can fire about a hundred in the same time at a sustained rate.

Testing continued up until 1940 and with a prototype of a truck with the launch rails on the back. The design was approved for production before Germany invaded the Soviet Union in June 1941, and mass-production began after the first month of the war, where the multiple rocket launchers proved very successful. During the war, the launchers were taken with much secrecy and operated by specialized troops such as the NKVD who do not even know its true name. Through the presence of a "K" on the vehicles from the Komintern Factory, the soldiers operating decided to nickname these launchers ''"Katyusha"'' after a popular wartime song of the same name. Up to 3,237 of all types of Katyusha launchers were produced from 1941 to the end of 1942, and more than 10,000 were made by the end of the war.

===Advantages and disadvantages===
Compared to the contemporary artillery systems of the time, the multiple rocket launcher system presented a different kind of artillery barrages used in the field. Advantages the multiple rocket launcher was that they were simple, extremely effective in saturation bombardment, fires lots of ordnance in a small time span, and were usually attached to mobile vehicles that can permit a quick retreat after firing to prevent counter-battery firing. Disadvantages with the system were that the rockets took a long time to reload, less accurate than regular artillery guns, and cannot sustain fire for a long period of time. However, in the battlefield, the multiple rocket launcher induces a greater psychological effect onto the targets on the receiving end due to the heavy amount of explosives able to be delivered in a short time. A battery of only four launchers could deliver their salvos of about 4.35 tons of explosives in a span of no longer than 10 seconds at a 400,000 square meter area.

===Designations===
Multiple variants of the multiple rocket launcher systems were made in the course of the war as the design is simply the attachment of launch rails onto a variety of vehicles. Each vehicle has different names that follow a template to distinguish their types.

* "BM-x-y" indicates a ground vehicle.
* "M-x-y" indicates a towed variant.
* "y-M-x" indicates a naval variant.

and "x" stands for the missile model while "y" stands for the number of launch rails available for the launcher variant. For example, the BM-8-16 indicates a ground vehicle firing M-8 rockets with 16 rails available to mount on.

Vehicles using the Katyusha launchers range from trucks, cars, and tanks. The production started with trucks such as the ZiS-6, then moving on to STZ-5 artillery tractors, then on Allied Lend-Lease vehicles. The 82 mm M-8 rockets, which saw service in August 1941, was the most popular rocket variant and saw use on the trucks and even tanks, which would make the '''BM-8-24''' rocket launcher tank mounted on the [[T-60]] light tank. Another attempt with tank mounting was with a [[KV-1 (L-11)|KV-1]] heavy tank as the ''KV-1K'', but as a waste of heavy armour, this was scrapped.

===Combat usage===
The Katyusha rocket launchers first saw service during the opening of Operation Barbarossa against Germany. On July 14, 1941, under the experimental battery commanded by Captain Ivan Flyorov, seven launchers were used in Rudnya and were able to cause massive destruction to the Germans in the town before they fled in panic. This success prompted the Red Army to build up more Katyushas in their inventory and raise more batteries and regiments for the vehicle. All these units were under NKVD control for secrecy until the Germans reveal their own multiple rocket launcher systems, the Nebelwerfer. The Germans nicknamed the Katyusha launchers as the ''"Stalin's Organ"'' after Joseph Stalin and how the launchers are organized in a way to look like a church organ. This German nickname became widely known in other areas in Western Europe. By the end of 1941, eight regiments and 37 independent battalions were available with a count of 554 Katyushas total.

The rocket launchers continue to become more integrated into the rest of the army as the war continued. Heavy mortar battalions were armed with the newer M-30 rocket launchers with heavy 300 mm M-30 rockets on June 1942. In July, a battalion of rocket launchers was added into the tank corps. The organization and equipment of these mortar battalions equipped with the Katyusha continue to increase and by the end of the war in 57 regiments, about 518 batteries of Katyusha launchers were available.

===Legacy===
The Katyusha launchers, issued in large numbers in the Eastern Front, was largely successful in the strategic effect of the war, granting the Soviet Union the ability to lay down a very heavy and shocking bombardment very quickly. The success of the system prompted many other countries to pursue such a system as well, such as the modified [[Calliope|T34 Calliope]] based off the Sherman and the Germans [[15 cm Pz.W.42|Panzerwerfer 42]]s. Today, the multiple rocket launcher system is still widespread with the implementation of newer technology, rockets, and missiles that make the rocket launcher system a very potent weapon to anyone on the receiving end.

=== In-game description ===
Based on the T-60 light tank, the first BM-8-24-class self-propelled mount featuring a jet-based volley-fire system on a tank chassis was built in 1941. At first the self-propelled mount was released on the basis of the T-40 light tank, but it was later replaced on the assembly line by the T-60 tank, and production continued on this basis.

The jet-based artillery subdivision of which the BM-8-24 MRLS SPG was a member was subordinate to Supreme Command. Jet-based artillery divisions were assigned to divisions and added to long-range (LR) divisions.

A total of 44 T-40 tanks were re-equipped as volley-fire installations.
