-Unguided 300-mm M-30 rockets were used by the Red Army since 1942 as a field artillery, being fired from metal frames right in the transporting containers. Soon, an upgraded version of the rocket appeared under the designation M-31 with an improved engine and a significantly increased range. Engineers from the special design bureau of the Moscow Kompressor plant designed a combat vehicle on the chassis of the US-built Studebaker US6 three-axle truck with a framework of 12 welded rails to launch these powerful rockets. The machine was successfully tested in the spring of 1944 and was put into service in June under the designation BM-31-12. In the troops, by analogy with the Katyusha MLRS, the new vehicle was nicknamed Andryusha (“little Andrey” in Russian).

 Rocket launchers Andryusha were widely used in the battles of the final stages of WWII in Europe, including the urban battles as a fire support for Soviet storming troops. In total, the Red Army received 1,807 BM-31-12 Andryusha vehicles until the end of the war.

 The '''{{Specs|name}}''', also known as "Andryusha", is a premium gift rank {{Specs|rank}} Soviet tank destroyer {{Battle-rating}}. It was introduced in [[Update "Sky Guardians"]] as a reward for the [[wt:en/news/8227-event-legend-of-victory-bm-31-12-andryusha-en|2023 Legend of Victory event]]. A highly unusual vehicle, reminiscent of its smaller brother, the [[BM-13N]]. Not only is its truck-based configuration not the most common, but it also uses 12 x 300 mm M-31-UK 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|hydropneumatic suspension system]] usually found on higher rank vehicles. Its gameplay is best compared with its smaller sibling, the [[BM-13N|BM-13N "Katyusha"]].
-The Andryusha is an artillery piece, belonging more in an artillery formation than in a tank battle. One should stay at a distance from the enemies since its rockets have a blind zone of about 300 m in front of the truck when moving on a flat surface.

-Being designed for rear-line support, the  BM-31-12 lacks any real armor. Being a simple truck, even rifle-calibre machine gun can penetrate the vehicle and knock out the two crew members. Therefore, the vehicle is extremely vulnerable to overpressure (HE shells, rockets, bombs and artillery strikes) as well as strafing aircraft and tank coaxial/roof machine guns. It is best to play at a distance from the frontline and with some cover nearby to retreat behind once the enemy presence increases, as your mobility isn't great either.

 '''Artillery'''
-Usage of this vehicle in its intended role of rear-line support and artillery strike. One should estimate the correct angle, shoot a rocket, watch where it lands, adjust fire, and retry it as needed. Do not take too much time with this method of rangefinding since a single retaliatory shot can end your day. Once the correct sight distance is found, unleash hell on your enemies, blinding them with dust lifting up from the ground, detonating ammo racks and blasting off tracks. This is basically an intelligent artillery barrage. Once all rockets are fired, fall back behind allied lines, find a captured objective to reload at, and repeat. Keep in mind that firing the M-31-UK rocket have a very loud launch noise, and will alert enemies all around to your presence.

-There is little the Andryusha can do against enemy aircraft, which can kill the vehicle with as little as a half-second machine gun burst or a relatively close detonation of a bomb or rocket. Try not to get caught out in the open, and try to hide behind obstacles. Its always recommended to have friendly cover while playing this vehicle.

 '''Ambusher'''
-Best used in an urban or dense maps, where enemies usually will rush down a path or corridor quickly without checking all of their sorroundings. Find yourself a pile of rubble or other kind of short cover and lower the front suspension of the truck in such a way that you can fire right in front of you just past the obstacle. When an enemy passes by, simply hit it with a rocket. This tactic is often a last resort when you're cornered and encircled. You may kill one or more enemies if you're lucky, but you will eventually be caught or your rockets will run out.
