The BMP-2 (Boyevaya Mashina Pekhoty, infantry combat vehicle) is a second-generation, amphibious infantry fighting vehicle introduced in the 1980s in the Soviet Union, following on from the BMP-1 of the 1960s. The BMP-2 is amphibious with little preparation, using hydrodynamic fairings to convert track momentum into water jets.
The main armament is a stabilized 30 mm 2A42 auto-cannon. The gun has a selectable rate of fire, either slow at 200 to 300 rounds per minute or fast at 550 rounds per minute. The original stabilization provides reasonable accuracy up to a speed of about 35 kilometres per hour.
