ASU-85 – WalkAround

The ASU-85 (Russian: Авиадесантная самоходная установка, АСУ-85, Aviadesantnaya Samokhodnaya Ustanovka, ‘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.
