GAZ-68

The GAZ-68, also known as the KSP-76, was an experimental Soviet wheeled self-propelled anti-tank gun, developed in 1944 by the design bureau of the Gorky Automobile Plant under V. A. Grachev. It had a welded hull of rolled steel plates from 3 to 16.5 mm thick with an open roof, and carried a ZIS-3 gun that could fire up to 15 rounds a minute at ranges of up to 13,300 metres, with 54 rounds on board. The chassis was taken from the experimental GAZ-63 truck, with both axles driven, which gave it a low silhouette. It was meant to serve as a roving fire-support weapon, but front-line trials showed it was not manoeuvrable enough for that task, so work on the KSP-76 was stopped and it was never produced in series.
