The BM-13N is a premium gift Soviet tank destroyer also known as "Katyusha". It was introduced during Update 1.67 "Assault" as part of the 2017 Victory Day Event. It later returned as part of the Hot Tracks trophy and is currently only obtainable from different trophies or the marketplace via a coupon.

One of the most unusual vehicle in game, to say the least. Not only is its truck-based configuration not the most common, it also uses 16 x 132 mm M13 rockets as its main armament, has limited traverse, has only 2 crew members, and a gun depression of +8°. The last is somewhat compensated by its ability to lean forwards with a hydropneumatic suspension system usually found on Rank 5 vehicles and up. Its gameplay is somewhat comparable to other rocket-armed premium machines such as the T34 Calliope or Panzerwerfer 42, but remains a rather unique experience.

The Katyusha is an artillery piece, belonging more in an artillery formation than in a tank battle. One should stay at a distance from the enemy since its rockets have a blind zone of about 250 m in front of the truck when moving on a flat surface. This is best used as it was back in the days: to support allies.
