== Description ==

The '''{{Specs|name}}''' is a rank {{Specs|rank}} Swedish tank destroyer {{Battle-rating}}. It was introduced in [[Update 1.97 "Viking Fury"]].

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


Survivability of this tank is bad for multiple reasons.

It's most likely that the Pvkv won't survive even one direct hit due to how the crew is allocated. Additionally, if the driver gets taken out, or even worse, an engine or transmission is damaged, the {{PAGENAME}} can only shoot in a small area in front of the tank due to the turretless design.
[[File:Hulldown in Pvkv m-43 (1946).jpg|thumb|right|Stay away from enemies, occasionally check your front to avoid getting suddenly obliterated, keep sniping.]]
The frontal armour has a maximum effective thickness of around 80 mm of rolled homogeneous armour when fighting head-on, which won't save it from any shots at its BR. On the side, the SPG have 30 mm maximum protection, and on the rear 25 mm. Lower frontal plate armour is exactly the same as the [[Strv m/42 EH]], since they both share the same hull. Because the vehicle is open topped, no matter what the user does it will always be very vulnerable to the aircraft and HE. Even 7 mm MGs can destroy it in one or two precise bursts.

To survive, the {{PAGENAME}} must stay as far away from enemies as possible to reduce their shells' penetration power while also angling in both horizontal and vertical plane to increase its raw armour value. The easiest way to do that is to find a hill which still allows the gun to fire down, but angle the Pvkv as much as possible, then angle to the left as much as the gun allows the Pvkv to do so (since it can turn further to the right). At about 800 m range it becomes difficult for the light tanks to penetrate the frontal armour, at about 1,200 m range, when angled in both dimensions, armour will be able to sometimes deflect even German APHE (as long as it's not fired by a heavy SPG, which have incredibly high penetration).

In AB, an aggressive playstyle will put you at a disadvantage, it's a good idea to relocate between shots so that the enemy has problems aiming at the Pvkv. In RB, it's usually unnecessary as any enemy will have terrible zoom and will probably miss at least once before landing any kind of a hit.

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


{{tankMobility|abMinHp=582|rbMinHp=363}}

The mobility of the Pvkv m/43 (1946) is nearly identical to the [[Strv m/42 EH]]. Driving forward, it can easily reach 40 km/h, even on rough terrain, so you will likely be one of the first vehicles at the cap. While shining when moving forward, the tank destroyer is slow in reverse, with a maximum speed of -5 km/h.

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

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

The main gun is the 75 mm pvkan m/43 cannon. While having excellent penetration and velocity, the reload is, considering the calibre and the open top, pretty long at 8.7 seconds with unskilled crew. In comparison, the German 75 mm guns only take about 6.5 seconds to reload.

The gun accuracy is pathetic until all accuracy modifications are researched, being reliable only up until ~600 m range until then.

The tank destroyer has no turret, it can only move the gun in about 33° arc in front of the tank, with 7 more degrees possible to the right. The gun depression of -15° is great, and the elevation of 20° is average.

The gunsight has an excellent magnification of 8x-16x, which is amazing. Most opponent will have around 1.5x-3x, making it well equipped for sniping.

==== Ammunition ====

The stock shell is the '''slpprj m/41''' uncapped AP shot with decent penetration, but poor post-penetration values. Also, it tends to ricochet.

Once you unlock the '''slpgr m/43''' APCBC shell, which is unfortunately a Tier IV modification, you have almost the best regular ammunition at the battle rating. The shell is similar to the one used by the [[Pvkv II]], though it has slightly less penetration because of the lower muzzle velocity. Though its a bit slower, it still can penetrate any heavy tank within BR range on direct hit, and at point blank range it usually can penetrate tanks relying on angled armour (but not always). Also the shell does high post-penetration damage, because of the 110 g TNT filler.

The HE '''sgr m/38''' is useful when dealing with open topped SPG at the rank, as they tend to sustain or bounce kinetic shots. Avoid using it on [[Sturer Emil]] or the likes of it without the element of surprise, as it has superior gun depression and will annihilate the {{PAGENAME}} before it can even fire.

== Usage in battles ==

The Pvkv m/43 (1946) is an excellent sniper due to its amazing gunsight zoom, great gun depression and deadly cannon. This tank destroyer unfortunately cannot perform as well when played as a regular tank, as it lacks the agility, gun traverse, and armour to flank or confidently take hits. Thus, to best utilise its sniper potential, the player must memorise various spots for sniping on different maps.

Good spots particularly for the Pvkv m/43 (1946) often have the following characteristics:

* The spot is at a good distance from the front line (around 800-1,200 m): obviously, the long range is to take full advantage of the superior gunsight zoom of 16x max. With this sight, the Pvkv m/43 (1946) is able to observe distant environment with unmatched clarity. The further it is from the target area, the harder it is for the enemies to effectively spot, aim and hit the player, while the player can still comfortably aim.
* The spot has a slope: hills or light inclines allow the Pvkv m/43 (1946) to perform hull-down when fighting. The Pvkv m/43 (1946) has -15° gun depression which is generally enough to depress the gun behind most hills. When hull-down, the tank destroyer presents a much smaller profile, increasing its concealment; it also significantly betters the frontal protection, as the frontal armour of angled 70 mm is now at a greater angle, allowing it to deflect more shells. When used in conjunction with range, the Pvkv m/43 (1946) will be able to resist certain cannons like the US 75 mm M3 and the Soviet's 76 mm F-34.
* The spot overlooks a crucial passageway: this is the key to success for not only the Pvkv m/43 (1946), but for all long-range snipers in general. Such spots that afford a view on popular passageways will most certainly guarantee target supplies and can even strategically cut off the opponents' supports, leading to a victory. If the player gets to battle position quickly, destroying passing enemies will prevent them from getting to good positions/cap points on time at the start of a match. In later stages of a match, a sniper at such position usually means that any enemies going to the frontline to support will most likely be destroyed before reaching their destination, allowing friendlies to push deeper and strengthen their defence. Of course, it is vital to practice gunnery -- the targets will usually be busy driving far away at full speed! Missing a shot due to poor lead can result in some allies being destroyed by the target you failed to destroy.
* The spot has vegetations and/or hard covers: plants can partially cover up the Pvkv m/43 (1946), delaying the time before enemies spot you in RB/SB. Hard covers give a safety shelter in case the player is being targeted. Vegetation can also sometimes prevent HE/HEAT from reaching the SPG, which is great, considering that the {{PAGENAME}} is open-topped and would otherwise instantly explode.

There will often be situations where the player needs to either push forward with the team or to retreat under attack. This is when good map-reading skills come into play: the great spots you fought at earlier might become dangerous when the tide changes. For example, a corner at the friendly side can become quite menacing as a few enemy pushes to there. Therefore you must practice how to quickly find new spots at anywhere on the map, as well as to correctly identify which new area/passageway to ambush. The Pvkv m/43 (1946)'s mobility allows you to change position in time. Custom battles provide a great place to practice such skills.

As the match progresses, you might lose the opportunity to pick on targets far away and instead have to enter close quarter combat. Although the Pvkv m/43 (1946) is now more vulnerable, with the right ambush position you will still be able to fight. However, one aspect to note is that the high gunsight zoom can become a problem in a face-to-face standoff. Most players are likely to subconsciously enlarge the zoom after entering sniper mode, and due to the high zoom, you will only be able to see an extremely limited part of the target. It will be more awkward if the target is moving. Therefore you need to not always use 16x zoom to adapt CQC.

'''Enemies worth noting''':

* [[R3 T20 FA-HS]]: this is a well known car, famous for its insane speed. It can appear at unexpected positions very early in the match and can be quite annoying to deal with. If an R3 charges at you from the front, your frontal armour can resist all its shells. Try your best to get your gun on target and finish it off before it can flank to your side. If, unfortunately, it gets to your flank, reverse and traverse the hull to aim your cannon to it while getting some separation. Note that the R3 is quite likely to get slowed down/stopped by obstacles like fences and trees due to its light weight, thus if you are at an urban/forest area the R3 may get stuck while circling, gifting you a few precious seconds to target it. In the worst case scenario, the R3 will tear through the Pvkv m/43 (1946)'s poor side/rear armour with its rapid firing autocannon and take out all your crew in an instant.
* [[KV-1E]] / [[KV-IB (Germany)|▀KV-IB]]: although the Pvkv m/43 (1946) carries a powerful cannon, there are still tougher nuts to crack, such as these two. They are uparmoured KV-1 models, featuring ~105 mm hull and turret armour on the front and parts of the sides. Armour of this thickness can be quite challenging to penetrate given that the Pvkv m/43 (1946) might usually be shooting over long distances. If the KV-1 is angling, hold your fire to avoid exposing your position. Only shoot if their armour is facing you without any angles, this is when you have the best chance to score successful penetrations. When shooting up close, try targeting the gun mantlet which is not covered by additional armour plates. Upon penetration, the KV-1 will often get crippled if not destroyed in one shot.
* [[Sturer Emil]]/[[Dicker Max]] (AB): These SPGs have better adaptability with terrain and generally it's impossible to attack them before they saw and attacked you. Their ammunition can breach even the strongest angled heavy tanks, let alone the pathetic armour of the {{PAGENAME}}. They also have a tendency to survive a single HE hit due to how they are constructed. Attack only if they look somewhere else, otherwise hide immediately and ask for an airstrike.

=== Pros and cons ===


'''Pros:'''

* Excellent gun for its BR once fully upgraded
* Very effective APCBC round with high velocity and adequate amount of explosive filler
* High magnification of x8.0-x16.1 - most tanks at the battle rating only have x1.5-x3.0
* Very good gun depression
* Machine gun can elevate to 90° and has a high ammo capacity of 2,000 rounds
* Trajectory of machine gun follows both APCBC and AP rounds trajectories close enough up to ~500 m
* Decent mobility
* Technically can survive SPG fire from 1.2 km if angled

'''Cons:'''

* Turretless design combined with poor reverse gear
* Low survivability and ineffective armour for head-on fights
* Machine gun performs poorly against lightly armoured vehicles and aircraft due to its low calibre
* Low versatility - the ultra high zoom can be annoying in close quarters and can make you vulnerable to flanking
* Long reload relative to its opponents
* Open top means enemy planes are able to strafe the vehicle and easily knock out the crew regardless of what you do
* Ridiculously bad stock experience due to the poor gun accuracy and poor stock shell, which tends to bounce off popular tanks even when it hits

== History ==


During World War 2, the need for tank destroyers became evident, and Germany had great success with the [[StuG III G|StuG III]] and StuG IV. Because of the success of those platforms, Sweden decided to create a tank destroyer similar in concept to the StuG's. Landsverk created a design in 1942, based on the chassis of the [[Strv m/42 EH|Strv m/42]]. It was chosen by the Swedish military and was given the designation Pansarvärnskanonvagn m/43, or '''Pvkv m/43''' for short.

The Pvkv m/43 used the chassis of the Strv m/42, but with a casemate superstructure replacing the turret. The superstructure was located at the front of the vehicle, and the glacis was sloped. It had an open tarp to keep the weight down, and used a tarp to protect the crew from the elements. The Pvkv m/43 had a crew of 4, and was initially armed with a 75 mm luftvärnskanonen m/36 antiaircraft gun, modified with a longer barrel for increased armour penetration. The gun could traverse 15 degrees to the left and right. It had a Ksp m/39 machine gun as the secondary armament. It was powered by a Volvo A8B engine producing 360 hp. The gearbox was different than the gearbox of the Strv m/42, and the drive wheels had to be reinforced to handle the increased weight of the vehicle. The Swedish military ordered 87 Pvkv m/43 in 1942, but deliveries were delayed and the last vehicle was delivered in 1948.

In 1954, the vehicle was given an armoured roof to better protect the crew. Other improvements included a muzzle brake, a gun rest, and a gas ejector. The Strv m/41 was retired from service in 1957, which allowed the two Scania-Vabis L603 engines per vehicle to be used in the Pvkv m/43. The two L603 engines produced less horsepower (320 hp) than the Volvo A8B, but were much more reliable. In 1970, the Pvkv m/43 was retired from service, and the guns were used in static fortifications until 1995.

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

The Sav m/43 has up to 50 mm of armour in front, which is capable of deflecting some guns commonly encountered but is still vulnerable to larger calibres. It has better frontal protection than the [[Ikv 72]], but is still rather lightly armoured from other angles. The engine deck is only 10 mm thick, and can be penetrated by aircraft heavy machine guns and cannons. The side armour is only 15 mm thick at most, and can also be penetrated quite easily by heavy machins guns and autocannon fire. Due to the cramped crew compartment and scattered ammunition within the compartment, any penetration by a shell is likely to cause critical damage to multiple modules and/or crew members.

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


{{tankMobility|abMinHp= 227|rbMinHp= 142}}

The Sav m/43 is based on the chassis of the [[Strv m/41 S-II|Strv m/41]] and thus has a similar level of mobility. It is considerably heavier, however, and thus correspondingly more sluggish. While the forward top speed is adequate, the reverse speed is quite poor, making it hard to retreat. It is also noticeably slower than the [[Ikv 72]].

=== Modifications and economy ===

== Armaments ==

{{Specs-Tank-Weapon|1}}

{{main|kan m/02 (75 mm)}}

The Sav m/43 is armed with the 7,5 cm kan m/02, an older and weaker 75 mm field gun compared to that used in the [[Ikv 72]]. It has wider traverse arcs and higher maximum elevation, but less gun depression than the Ikv 72, though still quite good at -10 degrees. It starts off with the unremarkable '''slpprj m/40''' uncapped AP shot, which is adequate against most opposition it may encounter but tends to suffer ricochets against sloped armour. However, once upgraded, the gun may fire the '''slpgr m/39''' uncapped APHE shell and the '''slpprj m/40B''' APBC shot. The former round has a very lethal 260 g TNT filler but tends to ricochet more and has less penetration, while the latter has better penetration and ricochets less, and is thus more useful in uptiers. It is recommended to carry a mixture of both APHE and APBC unless the Sav m/43 is top tier, in which case the APHE alone is sufficient.

== Usage in battles ==


The Sav m/43 (1944) is a more forgiving alternative to the [[Ikv 72]]. Like the Ikv 72, it performs best in a hull-down position, as it can use the depression to present a steeper angle on the frontal armour to increase its effective thickness. It has a relatively weak armour from the sides, top and rear, even if less vulnerable than the Ikv 72. It is best to play this vehicle cautiously since it has a slower manoeuvrability than the Ikv 72.

The armour on its own is adequate enough to survive most hits to the frontal armour at this battle rating, but leaving its side and rear exposed to enemies will make a quick work of it. Hence, it's a good support role vehicle to help allied vehicles by either finishing the enemies off or drawing attention to itself with the frontal armour so other allied vehicles avoid being targeted. Against heavier armoured vehicles or just vehicles with better guns such as [[M3 Lee]] and [[B1 ter]], it is better to avoid direct confrontation and not fight on equal terms.

While the gun is quite adequate against most enemies at its battle rating, it can be seen obsolete in uptiers where it will face opponents with considerably more armour. The gun might not be efficient in an uptier but it can still do damage if resorting to ambushing and shooting from hills, using the angled armour and the depression of the gun to its advantage. It can lock down areas and buy time for allied tanks to come to its aid doing flanking manoeuvres. The Sav m/43 (1944) can also move around to flank heavier armoured vehicles, getting to their side armour will give it a chance to penetrate and the ability to disable the better protected tanks when frontal engagement is not a viable option.

'''Enemies worth noting:'''

[[M4A3 (105)]] - The M4A3 (105) is a dangerous vehicle for the SAV m/43 (1944) to encounter, angled armour making the shells of the [[Kan m/02 (75 mm)|Kan m/02]] next to unusable against its angled frontal armour. It also got a gun with a HEAT shell that will make quick work of the Sav's armour and most likely detonate the ammunition or knock out the crew if it gets a good shot on the Sav. Best to stay away or ambush it where it shows off its less armoured and flat side armour.

[[B1 ter]] - The B1 ter has an armour thick enough that it can ignore the penetration capability of the SAV m/43's rounds, lacking in firepower compared to vehicles like [[M4A3 (105)]] or [[M3 Lee]], it can still do quite the damage with the 47 mm gun in the turret. The best way to eliminate this type of target is to either hit the less armoured turret or the flat armoured rear.

[[M3 Lee]] - Similar to the M4A3 (105), the M3 Lee's armour can prove to be quite resilient against the SAV m/43 (1944)'s shells forcing it to avoid the direct confrontation with the M3 Lee. The Lee is not just a well armoured medium tank, it also got a 75 mm anti-tank gun and a 37 mm gun in a turret which can prove to be efficient against the SAV m/43's armour. This makes it also a lethal opponent to face, where the best chance is to catch one off guard on the side or rear and attack the weaker side or rear armour.

=== Pros and cons ===


'''Pros:'''

* Decent frontal armour in a downtier
* Lethal APHE round, able to frontally penetrate and knock out almost any tank it faces with a single shot
* Wide gun traverse arc and good gun depression allows turret to acquire target without requiring constant adjustment of the hull
* Decent top speed
* Has smoke shells which can "lock down" an enemy area by shooting smoke shells there
* Adequate reload speed
* Has small silhouette

'''Cons:'''

* Low penetration works poorly against heavy targets such as [[M4A3 (105)]], [[B1 ter]]
* Very thin side, rear, and roof armour
* Very slow shell velocity, leading and shooting fast tanks (e.g. [[M22]], [[BT-5]]) is hard
* Curved shell trajectory demands precise aiming at long range
* Shells have weak penetration past 500 m
* Mediocre mobility and poor reverse speed

== History ==


In March of 1940, Sweden ordered about 90 TNH tanks (known as the Panzer 38(t) in German service) from ČKD, but Germany, which had occupied Czechoslovakia in 1938, confiscated the tanks for its own use as the Panzer 38(t) Ausf. S. Sweden still needed the light tanks, and after negotiations the Swedish manufacturer Scania-Vabis was allowed to produce them under license, and compensation for the lost tanks. Sweden ordered 116 Strv M/41 SI in June, 1941, and in June of 1942 Sweden ordered 122 Strv M/41 SII. The last 18 Strv M/41 SII were built as the Sav M/43 in 1944. Another 18 Sav M/43 were purpose-built afterwards. The Sav M/43 was a casemate assault gun made by removing the turret of the Strv M/41, and adding a casemate superstructure, initially housing a 75 mm gun. The 75 mm gun was replaced by a 105 mm M/44 Bofors cannon. The Sav M/43 served in artillery units until 1951, when they were given to armoured units instead. They served until 1973.

=== [[wt:en/news/6595-development-stormartillerivagn-m-43-en|Devblog]] ===
In 1942, Sweden began developing a new SPG built on a modified chassis from the Czech LT vz.38, better known as the Pz.38(t) in the German army. This new SPG was supposed to be equipped with the 75 mm L/31 cannon that was already in production. By autumn of 1942, a wooden model of the planned vehicle had been created and, after a number of improvements, the project advanced to manufacturing prototypes. Exactly one year later, in October of 1943, testing began. The SPG passed with flying colours and hit assembly lines under the designation Sav m/43 (short for "Stormartillerivagn", Swedish for "assault artillery carriage"). A little later, a version with a 105 mm gun came out, and, by the end of 1946, all m/43 SPGs had been re-equipped with this new cannon. The Swedish army had used this SPG until the early 70s. From the moment it entered military service until the end of the Second World War in Europe, the Sav m/43 vehicles were grouped by the Norwegian border and then assigned to infantry units as fire-support vehicles when the army was reorganised.

== Description ==

The '''{{Specs|name}}''' is a rank {{Specs|rank}} American light tank {{Battle-rating}}. It was introduced in [[Update 1.59 "Flaming Arrows"]]. Featuring a crew of six people with a 37 mm gun, it has a rather competitive armament for the size and battle rating. It is also the second amphibious ground vehicle to be added into the game.

The LVT is unique among the Rank I vehicles, given its ability to float across deep water. It has extremely thin armour that can easily be penetrated by heavy machine guns. In some areas even a light machine gun can penetrate it. It mounts a lightened Stuart turret, giving it a decently fast firing 37 mm cannon. Additionally, despite its rather large size (relative to its peers) it is quite mobile due to its light weight, able to keep pace with the M3 Lee.

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

Its large and spacious hull might seem hard to knock out all of its crew, but that's only true when you are getting shot from the side. From your side, there is a huge empty area between the driving compartment and the fighting compartment that will absorb any shell, regardless of their explosive fillers. However an experienced player will know to shoot at these two compartments and avoid the empty space. From the front, the spacious hull does not help to keep the crew safe as a penetrating shell will travel through the empty space and hit any crew at the back, so you could die sooner than you expected. Avoid tanks with solid shots, for example British/Swedish tanks.

'''Armour type:'''

* Rolled homogeneous armour
* Cast homogeneous armour (Gun mantlet, Machine gun shield)

{| class="wikitable"
|-
! Armour !! Front (Slope angle°) !! Sides !! Rear !! Roof
|-
| Hull || 12.7 mm (31°) ''Front plate'' 6.35 mm (83-84°) ''Upper glacis'' 6.35 mm (41-81°) ''Lower glacis'' || 6.35 mm (11-51°) ''Top'' 6.35 + 6.35 mm ''Bottom'' || 6.35 mm (0-62°) || 6.35 mm

|-
|}
'''Notes:'''

* Suspension wheels and tracks are 15 mm thick.
* Front hull has flat armour area where driver & co-driver sits.

The deadliest threats are HMG and autocannon mounted vehicles such as the Pz.II's, T-60, and AA guns. They can quickly chew through all of the crew.

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


{{tankMobility|abMinHp= 387|rbMinHp= 221}}

The LVT's mobility is adequate. On hard surfaces it easily reaches its top speed of around 38 km/h. On soft surfaces it needs more time to accelerate, and the top speed is lowered. The reverse speed is extremely poor, which can cause you to take unnecessary hits. The hull traverse is great, allowing you to quickly change direction, however a downside is that when you turn the hull to aim, you might over-turn and swing the gun past the target, increasing the aiming time which can be fatal.

Due to its big and tall tracks, the LVT can drive over some obstacles that are too tall for normal-sized tanks.

The M1919 machine guns are mostly an afterthought on the LVT. The rear machine gunners are exposed to bullets and are most likely the first knocked out in engagements. The bullets are only useful against some light tanks and open-topped vehicles. The LVT can double as an anti-aircraft platform as well, because the elevation on the coaxial and rear machine guns is better suited for this task.

== Usage in battles ==

Use the LVT(A)(1)'s ability to sneak up waterways to work around the enemy lines, and ambush when possible. If that is not a option, come at them head on, either taking their vehicle out or disabling it long enough to get around and finish it with a side shot. Once done, do not take the waterways back as the LVT(A)(1) is much faster on land.

This tank has the capability to work as an early assault tank, not as fast as the Stuarts, BTs and other light tanks.

Another tactic that can be done against lightly armoured vehicles is to drive backwards towards the enemy. The combined firepower of 3 machine guns and the cannon increases the chance of take out the enemy before they can take out the LVT(A)(1).

The big thing to keep in mind is that the LVT(A)(1) is big. It is a large target that is hard to hide, but the spacious interior makes it harder for enemies to take out all of the crew members.

At the same time, keep in mind that the LVT(A)(1) is an easy target for aircraft, as the vehicle presents as very easy target for anything .50 cal and up.

=== Pros and cons ===


'''Pros:'''

* Very fast and manoeuverable on most terrain
* 6 crew members
* Fast-firing and accurate 37 mm gun
* Crew members are spread out, less likely to get knocked out in one shot
* Great gun depression at the side and front
* Heavily armoured gun mantlet
* 2 machine gunners that can fire at high angles, enabling anti-air
* Small engine makes it hard to hit
* Reserve tank (no repair costs)
* Amphibious (the first reserve floating tank)
* Most of the interior is empty space meaning that most tanks will need a few shots to knock out this tank

'''Cons:'''

* Huge (shell magnet)
* Barely any armour to speak about
* Exposed lower glacis
* Weak armour and huge size makes it vulnerable to artillery
* Can easily be destroyed by HE shells (overpressure).
* Very slow reverse speed can prevent it from retreating back to cover in time
* Unstable aim while moving
* Bad suspension makes it unstable at humps
* Very slow speed when traveling in water
* Water rocks the tank when moving, making it unstable during and a while after movement in the water
* Poor Gun Depression in the rear in combination with it´s size makes it hard to hit smaller tanks who attack from the rear

===Development===
[[File:Roebling Alligator tractor - DM-SN-82-02381.jpeg|x200px|right|thumb|Roebling's "Alligator" that would serve as the basis for the LVTs.]]
The vehicle's origins is from a swamp-access vehicle called the "Alligator" made for civilians. Donald Roebling, its developer, built an improved version of his vehicle with better speed in water. The United States Marine Corps became interested in this amphibious design as they began drawing up their amphibious warfare doctrine. They requested a more sea-worthy version of the vehicle for use in their military operations. Though Roebling and the Navy were reclusive on that idea (the Navy believes they have the current vehicle in store already), the idea brought fruit when World War II broke out in Europe and Roebling created a military version. After a few trials with improvements like a stronger engine, the Bureau of Ships placed a contract for 100 of these vehicles with all-steel armour. The first ones arrive in July 1941, with 200 more ordered before the initial contract was finished. The vehicle design was adopted and designated the LVT, with many different variants of the vehicle being produced throughout the war.

===Variants===
[[File:LVT_amphibian_tractors_Guadalcanal_in_August_1942 - NH 97749.jpg|left|x300px|thumb|none|USMC LVT-1s as part of the Guadalcanal landings in August 1942.]]
The first version of the LVT, the LVT-1, could carry 18 men or 4,500 pounds of equipment. The Marines first used the LVT-1 in Guadalcanal with 128 available to 1st Marine Division. Usage in the field revealed that the LVT was too thinly armoured for a rapid deployment back and forth the ships and landing site, but the Marines saw the vehicle's potential as an assault vehicle. So in June 1941, the Marines push forward with a Roebling design of the LVT armed with a gun turret. In order for this to be possible, the LVT underwent a redesign into the LVT-2 "Buffalo", which had a new powertrain and suspension to allow better performances on land and able to carry up to 6,950 pounds in equipment. It was this design that the turret-equipped LVTs were created. The LVT-2s were armed with turrets from the [[M3A1_Stuart|Stuart series]] and [[M8_Scott|M8 howitzer motor carriages]]. These two turret variants are designated [[LVT(A)(1)|LVT(A)-1]] and [[LVT(A)(4) ZIS-2 (USA)|LVT(A)-4]] respectively. The (A) standing for "armoured" as the LVT was built with additional armour to withstand small arms fire. 510 of the LVT(A)-1 were created while 1,890 of the LVT(A)-4 were created.

Other variants of the LVT were produced featuring redesigns for its purpose of infantry fire support and cargo-bearing. Some of the significant ones was the LVT-4 in August 1943 that moved the engine forward and had a rear ramp door, which increased capacity from 18 soldiers to 30, making previous load-carrying LVTs obsolete. The LVT-4 was the most numerous of the LVT variants at 8,351 units.

===Combat usage===
The first usage of the LVT family is as a cargo carrier in Guadalcanal, it was unarmoured at the time and only had machine guns as their main armaments. Their next usage was in Tarawa, which saw the first usage of the newly designed LVT-2. The vehicles in both cases carried ammunition, troops, and wounded back and forth the ships and the beach. After Tarawa, the LVT inventory increased by the battalion, as well as the appearance of the gun-armed LVT(A)-1 and LVT(A)-4. The LVT family continued to see service in Bougainville, the Marshall Islands, Saipan, Peleliu, Leyte (its largest usage in the war), Iwo Jima, and Okinawa. The LVTs also saw use in South East Asia in use by the British, but they never saw combat action.
[[File:LVT(A)-1 amphibious vehicle at sea c1944.jpg|x250px|right|thumb|none|A LVT(A)(1) at sea.]]

Outside the Pacific, the LVT also saw use in the European Theater of Operations. Their first usage was in North Africa in November 1942 during Operation Torch to land troops, where its best usage was to get stranded landing boats back into action. The LVTs were also given to the British as part of Lend-Lease. The LVTs were used in the Normandy landings and other operations in Europe such as crossing the Rhine River in Germany and Po River in Italy.

After World War II, the LVTs continued to see action in the multiple conflicts in the world. A number were given to the Chinese Nationalists in the Chinese Civil War by America. Many of these were captured by the Chinese PLA, with some converted to use a 75 mm howitzer or a [[ZiS-2_(57_mm)|ZIS-2]] anti-tank gun. The Americans used a number of LVT vehicles in the Korean War, notably the landing at Inchon and the attack on Seoul. The French also used American-supplied LVTs during the Indochina War and the Suez Crisis.

== Description ==

The '''{{Specs|name}}''' (shortened '''{{Specs|pseudonym}}''') is a rank {{Specs|rank}} Swedish tank destroyer {{Battle-rating}}. It was introduced in [[Update 1.97 "Viking Fury"]].

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

The fm/43-44 is a deceptively survivable vehicle from the front. Open-topped high-calibre tank destroyers and SPGs are seldom very well armoured, but this example is the exception, with 50 mm of armour covering the upper and lower plate as well as the turret face, with the tapering sides being 30 mm. The only frontal weak point of this vehicle is the shield directly protecting the breech, which is only 15 mm.

It's also manned by 5 crew members, two in the hull and three in the back, which really helps its survivability. Most of the cannons you'll be encountering around this battle rating are quite low calibre, meaning it will take a fair few rounds penetrating this vehicle to knock out all the crew. Additionally, it's nearly impossible to knock out this vehicle without detonating the ammo, as the crew in the front and back are completely separate from each other, so a shot entering one compartment won't cause any damage to the other, so after taking a shot you'll still either be able to fire the gun, or drive away, which is a huge advantage. A drawback of this vehicle though is in regards to its protection from the air, the crew operating the cannon have no armour protecting them from incoming air strafing, so even aircraft with weak machine guns can slowly chip away at this vehicle, additionally its also very vulnerable to artillery.

'''Armour type:'''

* Rolled homogeneous armour

{{tankMobility|abMinHp=227|rbMinHp=142}}

The mobility of this vehicle as well is deceptively effective. It can reach a max speed off-road of 42 km/h in RB modes, and 46 km/h in AB modes. It won't outpace many light vehicles, but it certainly isn't slow, and can easily cruise faster than most contemporary tank destroyers and medium tanks. Once upgraded, its hull traverse as well is effective, it can turn from stationary to re-position the gun and change direction easily, which is important for a turretless vehicle like this one. Its reverse speed is about average at 5 km/h, which will be enough to back out of sight into cover, but it won't save you if you're out in the open, so the lack of a fast reverse gear should play into where you choose to position.

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

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

{{main|fsthaub m/02 (150 mm)}}

This vehicle is equipped with a 150 mm recoilless rifle with a small ammo pool of only 10 rounds. It's only equipped with a single ammo type, a standard HE round which sports huge damage potential if it connects with an enemy vehicle, in most engagements with conventional tanks you will only need to connect the round to the vehicle to knock them out in a single shot, which eliminates the tedium spent aiming for particular weak points, which isn't very easy for this vehicle as the muzzle velocity is quite slow at only 285 m/s, meaning that ranging in the gun can be quite tricky. Another slight drawback is the gun depression, at only -4°, this does somewhat limit the locations you can play effectively, as this vehicle can't use many hills or ridge lines to shoot over.

As well as this, the reload is fairly long at 19.5 seconds stock, so if you miss a shot this vehicle will be quite vulnerable, especially considering that the average reload of small calibre guns around this battle rating is around 4 seconds, so an enemy could potentially fire on you 5 times before you reload.

Because of this, it's recommended that you use the rangefinder when engaging enemies that aren't aware of you, this way you can almost guarantee the round connects, although it's not wise to spend the time rangefinding if an enemy is aware of you, as in the time you spend sitting and waiting for the range to come in, your enemy will likely be firing at you and knocking out your crew. Ultimately this round won't have any trouble knocking out the vast majority of vehicles you can meet around the battle rating, the only challenging vehicle will be the French B1 Bis, if you engaging one of these tanks it's recommended to aim your shot for just beneath the turret, as this will cripple the tank, avoid hitting the front plate as this likely will result in no damage.

The fm/43-44 is also equipped with a hull mounted 8 mm ksp m/36 machine gun, it has no viability against armoured targets but can knock out exposed crew members of enemy vehicles. It's recommended to select it directly when using it however as aiming it accurately by eye isn't very easy.

== Usage in battles ==

[[File:Fm-43-44 1.jpg|thumb|300px|The fm/43-44 engaging an M13/40]]
The main trick to doing well in the fm/43-44 is to stay around cover, and to not advance too far into the map on your own. Due to the reload you can't afford to get caught out at close range as if you're unable to fire, an enemy can quite easily flank and disable you. To stay in the fight it's imperative you stay around some form of hard cover to retreat behind to reload, as this is the only time that you're really vulnerable.

Another choice to make is at what range you're going to engage at, and there are notable drawbacks and advantages for each distance. At close range the cannon is very very easy to aim which will land you a lot of easy kills, however it is much too easy to get caught out here, if you miss a shot an enemy has plenty of time to rush and flank you, as well as this even if you do land a shot and knock an enemy out, enemy enemies that are aware of you in the surrounding area will know they safely have at least 15 seconds to rush you while you're on reload. At long range your armour will be very effective, the weak spots are very hard to hit here and some enemies might not even be able to get through the casemate itself, but as the muzzle velocity on the round is so low, hitting targets at this distance is very tricky, and considering as you only have 10 rounds, you can't really afford to miss very much, as each shot fired takes up 10% of your ammunition effectively.

At long range you're much more survivable but much less effective at taking out enemies, and at close range it's much the reverse, able to engage enemies easily at the detriment of being much more vulnerable. The Goldilocks principle in this situation is as the analogy goes- 'in the middle', where you have the best of both worlds, in essence all you really need to do is position yourself in a location around hard cover, and far enough away that an enemy can't rush you on your reload cycle, this is the ideal spot to be to maximise your survivability and combat effectiveness, if you are in this sort of position and watching a corner or sight-line, it's a good idea to rangefind that corner or sight-line as when an enemy appears you'll already have the perfect range, this really is the idea spot for consistency, there are a few smaller caveats to consider however. As this vehicle is so vulnerable from the air it's a good idea to position yourself around some form of lateral cover, some buildings, a hill, some trees etc- just to give you a slight advantage when hiding from enemies. Another spot in the map to position yourself around would be a friendly capture point, if you're running out of ammunition you can simply drive onto one to replenish your stores, which won't always be necessary but if you start to notice you only have a few rounds left it'd be a good idea to make your way towards one.

If you're confident with your map knowledge or playing with some friends you can use this vehicle to be a bit more aggressive, as the armour is still very effective and if you have support from friends watching your flanks you can really be a battering ram for the team as no enemy vehicle is safe from your cannon, if this way of playing does sound appealing in any case try to stick around some friendly tanks, as they will be able to help you if you get caught out.

=== Pros and cons ===


'''Pros:'''

* Incredibly high damage output from the main gun
* Effective even when up-tiered
* Decent mobility
* Effective armour against low-tier vehicles; frontal armour sufficient against light autocannons and .50 cal machine guns
* Five crew members spread out within the vehicle, offering protection against being knocked out by a single shot
* High survivability against solid-shot munitions

'''Cons:'''

* Vulnerable to artillery strikes and strafing aircraft
* Long reload time
* Low ammo count (10 rounds)
* Poor gun depression at only -4°
* Slow muzzle velocity

== History ==

After the experimental Stormartilleripjäs fm/43 project, the Swedish army procurement division, known as the KAFT, asked Scania-Vabis on 11 November 1943, to design and build a prototype for a self-propelled gun with a rear-mounted superstructure. It was to be based off of the Spj fm/43 but with the engine moved forward and the fighting compartment moved to the rear; it retained the open-topped superstructure from earlier designs. The Stormartilleripjäs fm/43-44 (shortened to Spj fm/43-44) gained the nickname 'Trätoffelvagnen', meaning 'clog wagen' in English.

The Spj fm/43-44 was armed with a 150 mm recoilless rifle called the fsthaub m/02, a longer version of the gun mounted on the Spj fm/43. It weighed 10 tons and had a crew of five men: two loaders, a gunner/commander, a driver, and a machine gunner. The driver and machine gunner were located in front of the engine in the hull, while the rest of the crew was situated in the open superstructure at the rear of the vehicle.

The prototype was completed in August 1944, and it test fired seventeen rounds on 18 August, achieving a fire rate of four rounds per minute (15 seconds of reload). The vehicle later went on to mount different guns before the project ended in 1945, resulting in its use as a training vehicle.

Spj fm/43-44

U137463050: Added Armour Specs

== Description ==

The '''{{Specs|name}}''' (shortened '''{{Specs|pseudonym}}''') is a rank {{Specs|rank}} Swedish tank destroyer {{Battle-rating}}. It was introduced in [[Update 1.97 "Viking Fury"]].

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

The fm/43-44 is a deceptively survivable vehicle from the front. Open-topped high-calibre tank destroyers and SPGs are seldom very well armoured, but this example is the exception, with 50 mm of armour covering the upper and lower plate as well as the turret face, with the tapering sides being 30 mm. The only frontal weak point of this vehicle is the shield directly protecting the breech, which is only 15 mm.

It's also manned by 5 crew members, two in the hull and three in the back, which really helps its survivability. Most of the cannons you'll be encountering around this battle rating are quite low calibre, meaning it will take a fair few rounds penetrating this vehicle to knock out all the crew. Additionally, it's nearly impossible to knock out this vehicle without detonating the ammo, as the crew in the front and back are completely separate from each other, so a shot entering one compartment won't cause any damage to the other, so after taking a shot you'll still either be able to fire the gun, or drive away, which is a huge advantage. A drawback of this vehicle though is in regards to its protection from the air, the crew operating the cannon have no armour protecting them from incoming air strafing, so even aircraft with weak machine guns can slowly chip away at this vehicle, additionally its also very vulnerable to artillery.

'''Notes:''' 


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


{{tankMobility|abMinHp=227|rbMinHp=142}}

The mobility of this vehicle as well is deceptively effective. It can reach a max speed off-road of 42 km/h in RB modes, and 46 km/h in AB modes. It won't outpace many light vehicles, but it certainly isn't slow, and can easily cruise faster than most contemporary tank destroyers and medium tanks. Once upgraded, its hull traverse as well is effective, it can turn from stationary to re-position the gun and change direction easily, which is important for a turretless vehicle like this one. Its reverse speed is about average at 5 km/h, which will be enough to back out of sight into cover, but it won't save you if you're out in the open, so the lack of a fast reverse gear should play into where you choose to position.

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

{{main|fsthaub m/02 (150 mm)}}

This vehicle is equipped with a 150 mm recoilless rifle with a small ammo pool of only 10 rounds. It's only equipped with a single ammo type, a standard HE round which sports huge damage potential if it connects with an enemy vehicle, in most engagements with conventional tanks you will only need to connect the round to the vehicle to knock them out in a single shot, which eliminates the tedium spent aiming for particular weak points, which isn't very easy for this vehicle as the muzzle velocity is quite slow at only 285 m/s, meaning that ranging in the gun can be quite tricky. Another slight drawback is the gun depression, at only -4°, this does somewhat limit the locations you can play effectively, as this vehicle can't use many hills or ridge lines to shoot over.

As well as this, the reload is fairly long at 19.5 seconds stock, so if you miss a shot this vehicle will be quite vulnerable, especially considering that the average reload of small calibre guns around this battle rating is around 4 seconds, so an enemy could potentially fire on you 5 times before you reload.

Because of this, it's recommended that you use the rangefinder when engaging enemies that aren't aware of you, this way you can almost guarantee the round connects, although it's not wise to spend the time rangefinding if an enemy is aware of you, as in the time you spend sitting and waiting for the range to come in, your enemy will likely be firing at you and knocking out your crew. Ultimately this round won't have any trouble knocking out the vast majority of vehicles you can meet around the battle rating, the only challenging vehicle will be the French B1 Bis, if you engaging one of these tanks it's recommended to aim your shot for just beneath the turret, as this will cripple the tank, avoid hitting the front plate as this likely will result in no damage.

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

The fm/43-44 is also equipped with a hull mounted 8 mm ksp m/36 machine gun, it has no viability against armoured targets but can knock out exposed crew members of enemy vehicles. It's recommended to select it directly when using it however as aiming it accurately by eye isn't very easy.

== Usage in battles ==

[[File:Fm-43-44 1.jpg|thumb|300px|The fm/43-44 engaging an M13/40]]
The main trick to doing well in the fm/43-44 is to stay around cover, and to not advance too far into the map on your own. Due to the reload you can't afford to get caught out at close range as if you're unable to fire, an enemy can quite easily flank and disable you. To stay in the fight it's imperative you stay around some form of hard cover to retreat behind to reload, as this is the only time that you're really vulnerable.

Another choice to make is at what range you're going to engage at, and there are notable drawbacks and advantages for each distance. At close range the cannon is very very easy to aim which will land you a lot of easy kills, however it is much too easy to get caught out here, if you miss a shot an enemy has plenty of time to rush and flank you, as well as this even if you do land a shot and knock an enemy out, enemy enemies that are aware of you in the surrounding area will know they safely have at least 15 seconds to rush you while you're on reload. At long range your armour will be very effective, the weak spots are very hard to hit here and some enemies might not even be able to get through the casemate itself, but as the muzzle velocity on the round is so low, hitting targets at this distance is very tricky, and considering as you only have 10 rounds, you can't really afford to miss very much, as each shot fired takes up 10% of your ammunition effectively.

At long range you're much more survivable but much less effective at taking out enemies, and at close range it's much the reverse, able to engage enemies easily at the detriment of being much more vulnerable. The Goldilocks principle in this situation is as the analogy goes- 'in the middle', where you have the best of both worlds, in essence all you really need to do is position yourself in a location around hard cover, and far enough away that an enemy can't rush you on your reload cycle, this is the ideal spot to be to maximise your survivability and combat effectiveness, if you are in this sort of position and watching a corner or sight-line, it's a good idea to rangefind that corner or sight-line as when an enemy appears you'll already have the perfect range, this really is the idea spot for consistency, there are a few smaller caveats to consider however. As this vehicle is so vulnerable from the air it's a good idea to position yourself around some form of lateral cover, some buildings, a hill, some trees etc- just to give you a slight advantage when hiding from enemies. Another spot in the map to position yourself around would be a friendly capture point, if you're running out of ammunition you can simply drive onto one to replenish your stores, which won't always be necessary but if you start to notice you only have a few rounds left it'd be a good idea to make your way towards one.

If you're confident with your map knowledge or playing with some friends you can use this vehicle to be a bit more aggressive, as the armour is still very effective and if you have support from friends watching your flanks you can really be a battering ram for the team as no enemy vehicle is safe from your cannon, if this way of playing does sound appealing in any case try to stick around some friendly tanks, as they will be able to help you if you get caught out.

=== Pros and cons ===


'''Pros:'''

* Incredibly high damage output from the main gun
* Effective even when up-tiered
* Decent mobility
* Effective armour against low-tier vehicles; frontal armour sufficient against light autocannons and .50 cal machine guns
* Five crew members spread out within the vehicle, offering protection against being knocked out by a single shot
* High survivability against solid-shot munitions

'''Cons:'''

* Vulnerable to artillery strikes and strafing aircraft
* Long reload time
* Low ammo count (10 rounds)
* Poor gun depression at only -4°
* Slow muzzle velocity

== History ==

After the experimental Stormartilleripjäs fm/43 project, the Swedish army procurement division, known as the KAFT, asked Scania-Vabis on 11 November 1943, to design and build a prototype for a self-propelled gun with a rear-mounted superstructure. It was to be based off of the Spj fm/43 but with the engine moved forward and the fighting compartment moved to the rear; it retained the open-topped superstructure from earlier designs. The Stormartilleripjäs fm/43-44 (shortened to Spj fm/43-44) gained the nickname 'Trätoffelvagnen', meaning 'clog wagen' in English.

The Spj fm/43-44 was armed with a 150 mm recoilless rifle called the fsthaub m/02, a longer version of the gun mounted on the Spj fm/43. It weighed 10 tons and had a crew of five men: two loaders, a gunner/commander, a driver, and a machine gunner. The driver and machine gunner were located in front of the engine in the hull, while the rest of the crew was situated in the open superstructure at the rear of the vehicle.

The prototype was completed in August 1944, and it test fired seventeen rounds on 18 August, achieving a fire rate of four rounds per minute (15 seconds of reload). The vehicle later went on to mount different guns before the project ended in 1945, resulting in its use as a training vehicle.
