ASU-85

The ASU-85 (Russian: Авиадесантная самоходная установка, АСУ-85, romanized: Aviadesantnaya Samokhodnaya Ustanovka, ASU-85 – airborne self-propelled mount) is a Soviet-designed airborne self-propelled gun of the Cold War era. From 1959, it began to replace the open-topped ASU-57 in service. It was, in turn, replaced by the BMD-1 beginning in 1969.
