The 100 mm gun-launcher 2A70 (GRAU designation: 2А70) is a model of low-pressure rifled cannons designed in the Soviet Union by the KBP Instrument Design Bureau. Integrated into Bakhcha-U and Sinitsa turret modules, the gun equips the BMD-4, BMP-3, and BTR-90M infantry fighting vehicles. It is capable of launching the high-explosive fragmentation (HE-FRAG) 3OF32 and 3OF70 projectiles, as well as the 9M117 Bastion gun-launched anti-tank guided missiles (ATGM) and related systems.
China produces a similar gun used on the ZBD-04 IFV, using technologies licensed from Russia in 1996. The VN20 has a version with a 100-mm gun.
