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

Describe the history of the creation and combat usage of the vehicle in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).
