Usage in battles
The Strv m/31 is a light tank with poor armour. It shouldn't be used to rush into the heat of the battle or you will get knocked out very quickly. Its armour is inadequate, it can't even stop 12.7 mm HMG fire. Instead, it should be used to flank other enemy tanks, using your excellent speed to your advantage. The Strv m/31 has an unconventional armour layout. Its frontal area (eg.upper hull, glacis area) armour is very weak while the rear is really strong. This tank also has pretty good speed in reverse, so you can drive into battle facing backwards using your rear armour and engine to soak up damage.

Pros and cons
Pros:
- Access to APDS ammunition that can penetrate up to 105 mm
- APDS has high velocity, making it easy to aim at longer distances
- Very good reverse speed, it will save you in many situations
- Can bounce shots if angled properly
Cons:
- APDS has no explosive filler, multiple shots will be needed to finish off a tank
- Very weak stock shell (low penetration and post-pen damage)
- Armor is poor, even for a rank one reserve vehicle
- Acceleration and top speed is quite poor, will find itself getting outrun by most vehicles.
History
The Strv m/31 was built by AB Landsverk in 1932. The tank was advanced for it's time such as it's use of all welded armor and using periscopes instead of view slits. These features were desirable to the Swedish armed forces and was put into service in 1935. Only 3 were ever built before the German invasion in 1940 making it a very rare tank. It wasn't used for direct tank on tank combat ,despite being highly advanced, but were dug into the ground as static bunkers.
