 This vehicle was slightly different from the current design, being armed with only a single 2A42 30 mm gun and with four 9M133 Kornet missiles located on one side of the turret.The production model of the BMPT was introduced in 2002 which featured the twin 30 mm autocannons, the two independent 30 mm automatic grenade launchers, and the four Ataka missile launchers.When used in urban terrain, each main battle tank is deployed with two BMPTs.
