Role

A light amphibious 122 mm self-propelled howitzer at the divisional level, designed to replace the towed M-30 in motorised rifle formations. The turret is mounted on an extended MT-LB chassis, which lets the vehicle ford water obstacles unprepared by churning its tracks. The 2A31 gun — a development of the D-30 barrel — gives a range of up to 15.2 km with HE shells and up to 21.9 km with rocket-assisted projectiles. The M1 variant adds an automated fire-control system (“Mashina-M”), digital communications, and supports the “Kitolov-2M” guided round.
