== Description ==

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

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


The {{PAGENAME}} has 20 mm of frontal hull armour, which is not significant enough to stop anything larger than a 14.5 mm machine gun. But, the upper plate is angled very well and as such could possibly prevent low-penetration autocannons from damaging the vehicle; the hull front, with its slope, can offer from 20 mm on the lower glacis up to almost 90 mm of effective thickness on the upper glacis. The side armour is composed of two spaced plates, one 6 mm and one 10 mm plate (for a total of 16 mm). This is enough to stop low-calibre machine guns, but a .50 cal will penetrate the armour with ease. A fuel tank is located between the spaced armour plates of the left side of the hull, right beneath the turret; the fuel tank is able to absorb machine gun bullets, protecting the turret crew from the left side from machine gun fire. The rear of the hull has a surprising 20 mm of armour, enough to stop low-calibre machine guns.

The turret has 20 mm of all-round base protection. The turret sides and rear have a 5 mm appliqué armour layer, giving a total armour thickness of 25 mm. This is enough to stop machine gun bullets from penetrating. The gun mantlet has 35 mm of protection - enough to protect against some autocannons.

The only part of the vehicle that is vulnerable to heavy machine gun fire is the hull side and rear. The rest of the tank can only be penetrated by autocannons or anti-tank guns. Overall, the armour protection is light. The ammunition of the vehicle is stored in the very back of the hull and turret, and there is a lot of ammunition, so a round hitting there will be hard-pressed to miss the ammunition. Even a shot from the front will often lead to many ammoracks when it passes through the rear of the tank. The only major source of protection for this tank is the engine and transmission. They are located at the very front, right, of the vehicle. A shot through this portion of the tank will often be absorbed, especially chemical rounds and autocannon shells. If a shell manages to penetrate through the engine block, it must also go through a 10 mm armour plate, which absorbs most of the shrapnel. This increases crew survivability extensively. Besides, even if the engine block absorbs the shot the tank will still be immobilized. Because of the ammunition stowage, the CV 90105 will often die to only one shot. Overall, the armour of the CV 90105 is very thin and should not be relied upon, although it can protect the tank in certain situations.

'''Armour type:'''

* Rolled homogeneous armour (hull, turret, cupola)
* Cast homogeneous armour (turret front, gun mantlet)

'''Notes:'''

* Suspension wheels, tracks and bogies are 15 mm thick.
* Belly armour and the bottom plate above the tracks are 10 mm thick.
* Mudguards are 5 mm thick.
* Additionally to the external armour, armour plates are also found inside the vehicle:

'''Notes:'''

* Inner armour plates protect the sides of the crew compartment (the upper section over the tracks only).
* The engine is separated from the driver position and the crew compartment by an armour plate.
* The driver viewport is a weak spot as it is the only place where the inner armour does not overlap with the external armour.

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


{{tankMobility|abMinHp=1,038|rbMinHp=593}}

With an excellent off-road mobility and a top speed of 70 km/h, the {{PAGENAME}} rivals even top tier MBTs, giving the XM-1, AMX-30 Super and Leopard A1A1 L/44 a run for their money. It is also quick to reverse, reaching -43 km/h and has very quick neutral steering. The acceleration is above average and the high hp/ton ratio enables the CV90105 to climb most hills and slopes.

However, the light tank has tendency to fishtail in corners and at high speeds due to the high hp/ton ratio. Even slight steering adjustments at high speeds can spin the vehicle out of control: anticipate your braking phases.

== Usage in battles ==

'''Mobility'''

The CV 90105 TML has great mobility thanks to its powerful engine and light weight. With good top speed, a very quick reverse, good mobility in turns, and very good acceleration, this vehicle's mobility stays competitive even when uptiered to face 10.0 BR MBTs. With this advantage the CV 90105 TML is able to take early-game defensive positions, reach sniping locations, and quickly relocate around the map if needed.

'''Armament'''

Another one of this vehicle's strengths is its armament. It's equipped with second generation thermal sights in both gunner and commander/binocular views, which makes enemies very easy to spot and which is incredibly useful in night battles. This tank also has a scouting ability, which can be used to call for support from teammates and locate enemies on the map.

As for this tank's gun, the CV 90105 TML is armed with quite a powerful cannon that easily penetrates MBTs. It has access to both its stock APFSDS round, the DM23, and HESH and HEATFS shells. Although the stock shell has higher flat penetration, the DM23 outperforms it in angled penetration, which is the more important metric in most cases at this tier; most enemy armour will be well-angled. Still, it is useful to carry a few rounds of the stock APFSDS shell. The gun has a very good turret traverse speed which helps in situations where quick aiming is required.

'''Survivability'''

The CV 90105 TML's greatest weakness is its poor survivability. It is only protected by thin armour on all sides. Due to the internal layout of the tank, ammo detonations and single-shot knock-outs are very common. Cannon-calibre rounds are able to penetrate the CV 90105 TML's armour, and artillery and aircraft post a serious threat to this tank. The CV 90105 TML has effectively no anti-air capabilities and its thin roof armour makes strafing attacks dangerous.

All of this means that avoiding enemy fire must be a priority. The tank's mobility can be used to flank enemies and attack without their noticing. Indeed, engaging head-on is usually a bad idea, since that makes you a prime target for artillery strikes and attacks from aircraft. If there are enemy aircraft nearby, try to stay near cover (next to buildings, under trees, near bushes or rocks...) and avoid crossing open areas of the map.

=== Pros and cons ===


'''Pros:'''

* Excellent off-road mobility and top speed
* High reverse top speed and quick neutral steering
* Both commander and gunner have access to 2nd generation thermal sights
* Ability to scout
* Two-plane gun stabilizer
* Relatively wide and powerful selection of shells - M735 APFSDS (great against flat armour), DM23 APFSDS (great against angled armour), DM12 HEATFS (great against non-ERA, non-composite and light armour) and DM502 HESH
* Excellent mobility, gives the XM-1, AMX-30 Super and Leopard A1A1 L/44 a run for their money
* Can research the entire Swedish tech tree from rank 1 to rank 7
* Quick turret traverse
* Front mounted engine - can act as a protection screen for the crew
* High hp/ton ratio enables the CV90105 to climb most hills and slopes
* 14 turret mounted smoke shells - fires 7 at a time
* Laser rangefinder

'''Cons:'''

* Very thin armour, does not give the possibility to angle or sidescrape
* Vulnerable to artillery and powerful HE shells
* Lack of AA capability makes it vulnerable to aircraft
* Extremely loud engine, if you can just barely hear enemy engines, opponents can definitely hear yours
* No heavy-calibre or roof-mounted machine gun to deal with lightly armoured targets such as the Bradley or BMP-3
* Turret is mounted far back on the hull - needs to show the entire hull when peeking around corners
* Agility at high speeds can make you lose control of the vehicle
* HESH does next to no damage, even to light vehicles
* Huge ammorack in the rear of the tank - APFSDS shells can enter from the front and still detonate the ammunition at the back of the vehicle
* 3 crew members out of 4 are tightly packed in a cramped turret - hits on the turret are usually fatal

== History ==

'''Chassis'''

The Swedish company Hägglunds began development 1983 on a combat vehicle capable of both anti-tank and anti-air defence, at the request of the Swedish Army. Due to the nature of the multi-role request, Hägglunds went for a utility vehicle design similar to the ideas of the Swedish Air Force. Initial trials were done with 5 different chassis to determine optimal engineering solutions to the concept. Although the design was unified, trials showed several issues with the clutch and brake systems. This was solved by reconstructing the system altogether. To accompany this, the chassis was raised 35 mm, and tower placement was moved forward. Hägglunds were strictly against this decision but later stated that this adjustment contributed significantly to the great export success of the vehicle.

'''Turret'''

The 105 mm turret was a design by the French GIAT (now known as Nexter Systems). This turret was originally made for the [[AMX-10RC]], an armoured car entirely designed by GIAT. The turret was designed to survive heavy machine gun fire up to 14.5 mm. The turret sported a 105 mm F2 cannon capable of firing modern APFSDS rounds, along with a coaxial 7.62 mm machine gun. By the 1990s, the turret started to become outdated, which lead to GIAT modernizing the design with electrically-powered stabilizers for the main armament and sights. This lead to the version found on the CV 90105 TML, known as the TML 105 mm turret.

'''CV 90105 TML'''

The CV 90105 TML was unveiled to the public in 1994. The combination of the flexible CV 90 chassis and powerful 105 mm G2 cannon proved lethal. This private venture by GIAT and Hägglunds was strategic, as this concept allowed both companies to market themselves towards the export market. The CV 90 chassis was able to prove its flexibility by carrying large-calibre cannons for anti-tank purposes, while the TML 105 mm turret got to show its upgraded potential and tracked-vehicle performance, along with flexibility. Although this design never attracted any customers, the concept sparked debate regarding the future of light tanks. Hägglunds went on to successfully export their CV 90 chassis, though only via the IFV role, most notably with the CV 9030, which featured a 30 mm Bushmaster II. Larger cannons were later trialled on the chassis, such as the [[CV 90120]], carrying a Swiss Ordnance Enterprise 120 mm L/50. GIAT went on to market their TML 105 mm turret fitted on the MOWAG Piranha, marketed for the Middle East. Although having lesser success than the CV 90 chassis, their AMX-10RC is still in service, proving its reliability as a wheeled fire-support vehicle, boasting a deadly cannon.

=== [[wt:en/news/6617-development-cv-90105-tml-with-pre-order-bonuses-en|Devblog]] ===
Development of the CV 90105 TML began in the early 1990s as a joint venture of the Swedish Hägglunds and French GIAT companies. The idea behind the project was to create a capable new light tank as part of the Strf 90 family of vehicles, while using only components which were already available. On one hand, this would keep development time and costs relatively low, while on the other hand make the new vehicle more attractive to customers which already operated some of the CV 90 series of vehicles.

As such, engineers took the hull of the Strf 90 IFV and fitted it with the GIAT TML turret, housing a 105 mm G2 cannon - an upgraded version of the turret used on the successful AMX-10RC.

The first and only demonstrator vehicle was ready in 1994, undergoing various trials. Despite proving the project's viability, the demonstrator didn't convince any foreign operators to place orders for the newly developed CV 90105. As such, further development of the project was cancelled, although the idea of creating a 105 mm armed Strf 90 version would remain, resulting in a renewed attempt some time later, but that's a story for another time.

Bkan 1C

U44219816: /* Survivability and armour */

{{Specs-Card
|code=sw_bkan_1c
|images={{Specs-Card-Image|GarageImage_{{PAGENAME}}.jpg|ArtImage_{{PAGENAME}}.png}}
}}

== Description ==

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

The Bkan 1C is an SPG based on a lengthened [[Strv 103 (Family)|S-tank]] chassis. It mounts a massive 155 mm cannon firing powerful HE and HE-VT shells. It has an extremely quick reload of 3.2s, but is otherwise extremely sluggish, having only -2 degrees of gun depression, thin armour, and only 14 rounds.

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


The inside of this vehicle is effectively split into 5 areas: engine, left tower, right tower, the gun, and the autoloader. The side armour and overall survivability is negligible and enemies should only be engaged frontally if at all possible.

The engine compartment can deflect heavy MG fire, but autocannons fired straight at the LFP will probably penetrate the armour and immobilize the SPG. It is separated from the rest of the tank and is likely to block overpressure damage, as well as to stop APHE from reaching the fuel. The driver is also shielded with additional 5 mm RHA plates, so it is rare to lose him to a random shot. It is also rather rare for the enemies to focus on the engine when attacking frontally, as the giant gun is very distracting, but engine hits should be avoided, at least if the gun cannot attack the entirety of the enemy squad, as a lucky hit there can set everything on fire and stop ongoing repairs. If the source of the fires is indeed the engine, then it is possible to unload the entire autoloader onto the enemy before the fire even reaches the back crew due to the RHA plates in the way but, eventually, it must be dealt with.

The towers on the sides of the back house two crew members each, the right tower also houses vertical gun drives. It is very important to keep the left tower hidden, as the gunner resides there, and neither of the towers can block HMG fire even at medium ranges, as they are completely flat. It is also possible to destroy the entire tank by hitting the bottom of the tower with extremely powerful APHE, or sufficiently strong HE/HESH, but the further the BR goes, the less tanks will be able to deal any significant damage with their default preloaded ammunition.
[[File:Autoloader safety Bkan 1C.jpg|300px|thumb|right|While the practice of pulling the gun up while traveling is not common in WT tanking unlike with the real life, it is very useful for the {{PAGENAME}}, as it allows to hide the autoloader. Use "look around" button to lock the gun and to look around while driving.]]
The gun is covered by a net and can only traverse along the hull. It is very rare to have the gun itself taken out, unless intentionally targeted, whether it's because the decoy took a hit instead, or because the enemy aimed at the gun breech instead. Because the gun looks incredibly intimidating, most people fire straight in the middle of the SPG and take out no crew and only damage the gun breech or the vertical drives (which can be repaired back almost immediately). When the gun breech is damaged, the gun is effectively out, as even after the field repair the gun will constantly jam and do nothing, so do not bother with it and do a manual repair, in which case at about 50% of breech repair progress it will stop failing to fire. For this reason, it is not recommended directly fighting SPAA or autocannon light tanks, because they are scared of this weapon more than anything else and can disable it even by accident.

The autoloader is hidden on the top behind the gun. Unfortunately, it is placed very high and is generally exposed when fighting head-on. While it's extremely angled and will deflect stray shots, and the intentionally aimed ones are often absorbed by either the gun or the towers, it is not rare for some tanks to just fire at the autoloader and to actually hit it. Sometimes, if the SPG tries to rush through the fire without turning towards the enemy, an enemy APHE might not bounce off the chassis and instead overpenetrate the first armour layer and activate upon exiting the compartment, then sufficiently powerful explosion will detonate the autoloader, which is why any enemy should be faced head-on and any angles should be cut, if possible. If the gun breech was destroyed, the gun should be immediately pulled up to hide the autoloader behind the non-critical compartments, whether the SPG is retreating or doing a manual repair. (Refer to the picture for an example)

Due to the compartment separation, a hull-down {{PAGENAME}} can bully APDS-equipped tanks by only exposing the right side and the gun, as they won't ever be able to deal any real damage unless they load HE/HESH or somehow land a hit on the autoloader. It's also possible to use negative inclination (by facing downhill) against such tanks to resist heavy machine guns, since they do not use APHE and aim for the crew or the autoloader, so the fuel explosion is unlikely and the SPG does not become any more exposed than it already is.

When the autoloader is completely empty, it can work as a shield for the Bkan 1C. When completely pulled down to the ground (the gun is pulled up to the sky), the autoloader can stop any APHE or HE shells (even a direct hit from the [[G6]] won't penetrate) and might shatter small APDS rounds aimed at the SPG's hull. While it doesn't protect the entirety of the towers or the chassis bottom, the makeshift shield allows to use Bkan 1C as a point capture tank or a taunt device to some extent by driving backwards, as people generally think that the driver tries to escape, then shoot the autoloader, making them an easy target for others.

'''Notes:''' 


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


{{tankMobility|abMinHp=852|rbMinHp=531}}

The Bandkanon is slow, there is no way around it. Even at its best it is only as fast as a heavy tank and generally drives forward at 20 km/h on demand, then accelerates towards its maximum speed of around 30 km/h. Despite the reverse gear having similar top speed to the forward gears, the SPG will accelerate with it two to three times slower.

The tank has neutral steering, but it's too slow to be relied on in the heat of battle. However, when the spaded {{PAGENAME}} reaches forward gear 5 it can spin around at ludicrous speeds and can effectively do 360 spins towards any tank that is attacking it. Unfortunately, it won't work if the SPG is stuck in the mud, and in RB it is generally only possible on clean flat surfaces (like any roads). For that reason, having maxed out "tank driving" crew skill is almost required to operate the {{PAGENAME}}.

=== Modifications and economy ===

{{Specs-Tank-Weapon|1}}

{{main|kan m/60 (155 mm)}}

The {{PAGENAME}} can be effectively classified as an artillery tank, as it can only use a HE shell. Its gun has an insane 3.2-second automatic autoloader, which allows it to casually miss a shot only for the enemy tank to roll out into yet another HE aimed straight at the weak spot. No other heavy weapon reloads this fast. This also means that the only crew members truly important for the SPG are the driver and the gunner, as the reload time will always stay the same.

The gun is very accurate even when stock and will only miss near-impossible shots, but has terrible optics. The gun is not stabilized, but with the maxed out targeting it's difficult to even notice, unless driving over terribly uneven terrain. This is highly contrasted with the [[Ikv 91]] which has all of the aiming devices in the world and great optics, but sometimes manages to miss regardless.

The resupply time on a capture point is ~7 seconds. It's important to note that the gun's recoil is strong enough to break the manual repair and the resupply process on flat ground. This means, unfortunately, that it cannot just endlessly bombard an enemy team while reloading like some other tanks and can be eventually drained of all its ammunition, as it only has 14 shots. The only ways to counteract the recoil is to either angle the hull down on a slope or to support its back with something (for example, a building).

Horizontally, the gun can only aim in front of the hull and won't go past the headlights (on the hull edges). For this reason it is necessary to face the enemy at all times, aside from the autoloader safety concerns.

Vertically, the gun will easily go up as high as 40 degrees, which is usually enough, whether when attacking high ground, moving down, or shelling an enemy team from a capture point on another end of the map. It, however, will refuse to aim down more than 2 degrees and any fights against low ground or over uneven terrain should be avoided.

Even if it's certain that the gun can indeed fire down from the chosen uneven position, avoid moving as to not accidentally lock the gun just a degree too high above the target. Avoid panicking, as the gun can and will reload faster than 99% of the enemies will be able to move out, unless they all do this simultaneously.

The sgr m/60 HE shell has a muzzle velocity of a default APHE that most tanks use, which means that it is easier to aim than a regular HE shell, but also that if enemies can be aimed at, they can also aim at the {{PAGENAME}}, so retaliatory fire is inevitable.

The only way to avoid a counter is to annihilate enemy tanks faster than they can fire, which heavy HE can do. However, HE can only deal with tanks via overpressure damage and will not simply instantly destroy heavy tanks if the blast wave won't hit their bottom (by attacking the track from underneath the tank itself), suspension, roof, or other weak spots. Some tanks are also built to deny such ammunition and should be avoided as much as possible.

The HE-VT shell has very limited uses due to the muzzle velocity and ammunition load concerns, but it only reacts to actual vehicles it passes and generally ignores terrain, and as such can be launched directly over rocky terrain. It will usually explode next to the middle of a tank, whether it flies above or passes the sides, which allows it to save the {{PAGENAME}} from light tanks when they are attacking from the low ground or over cover, as even an inaccurate proximity HE detonation can often destroy them. For the same reason it can be used to bombard SPAA or other lightly armoured SPGs when they are hiding behind a hill with various degree of effectiveness. In extreme cases, it can be used to get rid of a strafing aircraft, as the proximity fuse will make hitting it slightly easier (but will fail as soon as they fire anything besides cannons). Against medium (especially Soviet) and heavy tanks, as well as the tanks with the turret on the very back, the shell is far less valuable, as it has a rather unpredictable behaviour - if fired directly at the tank, it usually works as a normal HE shell, but it may also randomly detonate before it reaches the tank when fired at the turret roof.

== Usage in battles ==


'''Arcade mode'''

In general, even a stock {{PAGENAME}} can fight on a frontline and obliterate tanks from 500 m to 1,500 m alike, but until the "parts" are researched, it is best to stick with allies or a capture point as much as possible despite low maximum speed. This is due to enemies instinctively (or by aim assist) spam firing into the gun breech, which will leave the SPG useless until it is repaired.

The stock {{PAGENAME}} is rather sluggish and you probably should park in such a way that allows it to back off. The main way to fight is to present the right side to the enemy and try to explode them before they manage anything. That way, they will fire at the commander tower and technically waste a shot (with maybe disabling the turret drive, which can be repaired back almost instantly), or fire at the gun and only damage the gun breech, so you can promptly run away and/or repair (do not forget to immediately pull the gun up when doing so to avoid being shot into autoloader and destroyed). If the enemy fires HE/HESH shells, you were simply out of luck to begin with.

Eventually, you want to end up on a capture point to reload. Try to plan your ammunition spending if you aren't being ambushed at literally every step, so that you can have at least 4 shells to clear a capture point. Do not get too enthusiastic with shelling a random [[Leopard 1]] across the map - even though it makes its job infinitely more frustrating and risky, it's not worth being obliterated by an enemy on or around a cap due to a lack of ammunition.

Try to avoid being flanked, but if that's impossible, or you see via "radio communication" that someone is very eager to flank and obliterate you specifically, drive forward until you hit the gear 5, then let go of the accelerator and turn. Initially the move will be rather sloppy, but when the {{PAGENAME}} is spaded and the crew driving skill is maxed out this trick will allow it to spin 90 degrees near instantaneously and to continue spinning for almost 300 degrees on flat terrain, allowing you to potentially obliterate several tanks in a 360-no-scope manner.

The gun is bad when fighting over hills due to poor gun depression, unlike early Sweden tanks, so it's better to attack from low ground, go into a city or to just start counter-sniping from long range (preferably with a capture point nearby and with accuracy upgrades, but can be done even from the spawn if you can tolerate the poor optics quality). The hills still can protect the autoloader when the gun is pulled up, at the cost of stealth.

While the gun can literally liquefy any tank by just randomly firing at it, try to retain patience and upon the first miss try to aim better while the gun reloads, if not for your own safety, then to conserve ammunition. Avoid fighting over cluttered streets or forests, unless firing straight from the capture point to waste less ammunition, as the {{PAGENAME}} does not have an MG to clean the shell flight path. Do not attack kinetic shell-armed tanks over a cluttered street if you aren't sure you can annihilate them within 2-3 shots, even if they do not see you. Even the densest tanker will notice that something explodes next to them when it happens for the 5th time.

When fighting heavy tanks, you can try to pretend that you are weak and bait them into chasing you, then attack their bottom by attacking the tracks, as it's the easiest, and sometimes safest, way to destroy them. If that's impossible just attack their roof (by hitting the commander cupola, for example). Area denial also works well against ATGM light tanks, such as [[BMP-1]], because being attacked by an ATGM means almost certain death to the {{PAGENAME}} due to how its armour works.

Do remember that a lot of German players on rank IV love to whip out their obsolete toys just to trash an opponent that bested them and SPGs like [[8,8 cm Flak 37 Sfl.]] or [[15cm sIG 33 B Sfl]] are insanely dangerous, both due to being nearly indestructible by normal means (leaving you to be the only one to be able to deal with them in one shot in an average team) and due to being able to fire lethal APHE or HE shots at angles at which the {{PAGENAME}} cannot fire back (due to the increased muzzle velocity of its HE).

'''Notable enemies'''

The [[Jagdpanther]] will sustain HE shells with its front glacis and it's very difficult to hit its roof. At close range, its bottom armour can be attacked with normal HE shells by hitting the tracks from underneath it. Avoid attacking into the high ground or hull-down position if it is there, you won't win.

Many American rank V medium/heavy tanks receive upgraded roof armour, which is often able to withstand HE shells unless hit straight into the commander cupola or inner sides of the tracks, and all American tanks have 12.7 mm HMG on top of them (and almost all US commanders use them immediately upon seeing any tank), which is effectively a death sentence if they can see the gunner tower. [[T32E1]] is a heavy tank with extra steps against HE shells; [[T29]] can survive a lot of roof-shot attempts despite being technically vulnerable; [[M48A1]] (which is also used by other nations and is often seen when playing against Germany) is only really vulnerable to cupola shots or from the sides.

=== Pros and cons ===


'''Pros:'''

* 3.2-second autoloader on a 155 mm weapon. There is no other big weapon reloading faster than this currently in the game
* It is difficult to take this SPG out with a single shot with kinetic shells from the front unless the ammo rack is detonated
** Crew is somewhat spread out, meaning single APDS and APFSDS shots are unlikely to hit all of them
* HE shells have higher muzzle velocity than the ones of the competition, making them easier to aim
* Can carry HE-VT shells, which, combined with the fire rate, make it extremely lethal at BR 8+ (rank VI for other nations), where the light tanks are abundant

'''Cons:'''

* Only 14 rounds
* Ammo rack is exposed and quite prominent even from the front
* Gun recoil strong enough to stop manual repair and resupply on a capture point, unless suppressed
* Very poor gun depression, limiting its use as a close-range support
* Poor gunsight zoom of X4
* Armour will not sustain autocannon fire, can be vulnerable to HMG at close to medium range, vulnerable to chemical rounds
* No turret, which is a downside for a tank forced to fight at a close to medium range, and is very vulnerable when its tracks are destroyed
* Many enemy tanks within natural BR range are built to survive HE attacks

== History ==


=== [[wt:en/news/7462-development-bandkanon-1c-the-nordic-doomsday-weapon-en|Devblog]] ===
In the late 1950's, Swedish engineers began work on a new self-propelled artillery unit, taking design choices proven from the previous Kranvagn experimental project and combining them with the modified chassis of the Strv 103A. The result of this undertaking was the Bandkanon 1, whose first prototype underwent testing in the early 1960's.

By 1963, serial production of the vehicle began with an initial order of 26 vehicles. Upon entering service, the Bandkanon 1 managed to set a world record for fire rate thanks to its autoloading mechanism. In fact, when firing at maximum range, the vehicle was capable of emptying its whole magazine before the first round fired even impacted, thus setting a world record for fire rate.

The 26 Bandkanon 1s were commissioned into service with artillery divisions in Norrland and remained in service there up until 2003 before being retired from active service.
