-The '''{{Specs|name}}'''also known as '''Landsverk L-10''', was designed and built by '''AB Landsverk''' during the Interwar period. For its time it was quite revolutionary, and it was considered a medium tank. It was the first tank to ever be produced with an all welded design, and it used periscopes for increased visibility, instead of the traditional view ports. It mounted a very common armament for the time, a 37mm L45 Bofors anti tank gun and two licensed produced Browning M1917 MGs. While the tank did serve with Sweden, only three were ever built, and the last one stays at the Swedish Tank Museum Arsenalen.

-Introduced in [[Update 1.97 "Viking Fury"]], the  Strv m/31 is a very light tank, with good mobility. Its armor is in fact so thin, that it cant stop 12.7mm HMG fire in some places, specially in the sides and back of the tank. However the tank is extremely well guned, it features the slpprj m/49 APDS shell, a very good shell for its rank, and even in uptiers it would remain competitive, since its mobility and armament are capable of dealing with higher BR enemies like the [[B1 ter]] and the [[Valentine (Family)|Valentine]]. The tank also has access to an APHE shell, but lacks enough armor penetration to be useful even against reserve tanks.

 Swedish tanks aren't very well known even by many enthusiastic historians or fans of military vehicles. However, many of the design and technological solutions conceived by Swedish tank designers were unique and rather practical. Sweden's armoured vehicles are truly fascinating, and the Swedish ground vehicle line in War Thunder will present to you some highly original tanks with one-of-a-kind features and gameplay finer points. We'll start our overview of the Swedish tech tree by looking at the first tank starting the progress of all the Swedish ground vehicles. Meet the reserve Strv m/31 (from "Stridsvagn", Swedish for "tank"), a 1935 light tank. According to some experts, this little tank came close to being the most high-tech tank of its time!
-In 1930, the Swedish firm Landsverk developed two tank designs – one fully tracked and the other with a wheel/track arrangement – differing in their chassis construction and armour. In the autumn of 1931, the Swedish government ordered four experimental prototypes – one wheel-and-track and the other three fully tracked. The versatile tank could switch from tracks to wheels in an incredible 30 seconds flat and reach speeds of up to 80 km/h in such a configuration! However, the wheels were unable to bear the weight of substantial armour, so it was limited to 14 mm for this modification. The fully tracked version could cope with armour up to 24mm thick, which is pretty respectable for a pre-war vehicle. Moreover, the designers took a risk by choosing welded armour plating over the more common riveted design, this also had its advantages. Even more interesting is that they set the angle of the frontal armour plate in order to increase the chance of enemy shells ricocheting. Put into service under the designation Strv m/31, the new tank was given the Maybach petrol engine, which was able to provide a power-to-weight ratio of approximately 17-18 horsepower per ton. The tank's armament comprised a 37 mm cannon with 122 rounds. All of the prototypes were put into service, though they required certain improvements. The vehicles' weak point was their unreliable and difficult-to-maintain suspension, as well as the tanks' overreliance on foreign-made components. The tanks were used as training vehicles.

-The Strv m/31 is equipped with a 37 mm kan m/38 cannon, a good gun for a tank its rank. The cannon has adequate accuracy which allows for the engagement of distant targets to some extent. It also has a short reload time of ~3.5 seconds ensuring quick follow-up shots if the first shell failed to knock out the enemy target, and an impressive -10° gun depression meaning the tank can comfortably fight among hills.

-The default slpprj m/38 round is very average, with around 50 mm of penetration which is usually enough to penetrate most tanks, such as [[T-26 (Family)|T-26]], [[M3A1 Stuart|M3A1]], [[Chi-Ha (Family)|Chi-Ha]], etc. The post-penetration effect is quite poor, but this is to be expected for a solid APBC shell. Good news is, the fast reload allows you to quickly pinpoint crews untouched by earlier shots.

The good news is the fast reload, which allows you to quickly pinpoint crew members untouched by earlier shots.
-The unlockable slpgr m/39 shell comes with a 15g explosive filler which can be very helpful given that most early-war tanks are cramped with small number of crew. This will result in the Strv m/31 easily knocking out in a single shot cramped tanks like [[BT-5]]/[[BT-7 (Family)|7]], [[Pz.II (Disambiguation)|Pz.II]], [[Ke-Ni]], etc. However this shell does have a slightly worse penetration than the default APBC, so it will struggle more against better armoured tanks such as an angling [[M13/40 (Family)|M13/40]].

Its velocity of more than 1,000 m/s is very fast, meaning sniping moving targets is easier.  Such velocity leads to a noticeably flattened trajectory, further easing the task of sniping. However, just like the default APBC, this shell has poor post-penetration damage, so be sure to aim for critical spots and use your fast reload well.

-The mobility of the Strv m/31 is in the top range. Though not as fast as tanks like BT-5, this tank is still able to lead the charge with its great speed (both on and off road). On average the Strv m/31 can cruise at around 42 km/h, allowing it to get to any location on time. The reverse speed is also great, topping at 19 km/h meaning the player can usually retreat from danger without turning around, increasing survivability. This also gives it more agility to conduct short range tactical manoeuvres. The hull traverse is slightly worse, often needing a forward/backward acceleration before turning. Overall, the Strv m/31 is fast and agile.

 The armour of the Strv m/31 is thin and should not be relied on. The frontal hull armour tops at 24 mm and is poorly angled, meaning that almost any tank can penetrate it (e.g. [[BT-5]], [[M2]], [[Pz.II (Disambiguation)|Pz.II]]), even the .50 cal! The hull side is 24 mm thick which can also be penetrated with ease, but sometimes if the enemy messes up their aim, an angled 24 mm side may bounce one or two shots.
-The turret front is weak against high-penetrating tanks like [[M3 GMC]] and [[Panzerjager I]], as it is still 24 mm thick and not angled. But against weaker small-calibre rounds it may be effective to some extent. The gun mantlet is full of 'obstacles' like the armoured housings for the coaxial MG, the cannon barrels and its hydraulic recoil cylinders which, with the implementation of volumetric shells, became fairly good at catching shells and making them lose penetration. Thus the parts where shells can actually go through without being interfered are very small and hard to target. Other than the gun mantlet, the rest of the turret when viewed from the front are of extreme angles which will certainly ricochet any shells. However when shot from other directions the turret is still poorly armoured and is very unlikely to stop any shell.

Even more interesting is that they set the angle of the frontal armour plate in order to increase the chance of enemy shells ricocheting. Put into service under the designation Strv m/31, the new tank was given the Maybach petrol engine, which was able to provide a power-to-weight ratio of approximately 17-18 horsepower per ton. The tank's armament comprised a 37 mm cannon with 122 rounds. All of the prototypes were put into service, though they required certain improvements. The vehicles' weak point was their unreliable and difficult-to-maintain suspension, as well as the tanks' overreliance on foreign-made components. The tanks were used as training vehicles.

 The mobility of the Strv m/31 is in the top range. Though not as fast as tanks like BT-5, this tank is still able to lead the charge with its great speed (both on and off road). On average the Strv m/31 can cruise at around 42 km/h, allowing it to get to any location on time. The reverse speed is also great, topping at 19 km/h meaning the player can usually retreat from danger without turning around, increasing survivability. This also gives it more agility to conduct short range tactical manoeuvres. The hull traverse is slightly worse, often needing a forward/backward acceleration before turning. Overall, the Strv m/31 is fast and agile.
