The SU-76 assault gun was the second most widely manufactured Soviet armoured fighting vehicle of World War II, out-numbered only by the legendary T-34. Inspired in part by the German Marder series of tank destroyers, Soviet designers realized that the chassis of the obsolete T-70 light tank could be adapted to a much more substantial gun if it was placed in a fixed casemate rather than in a turret. This led to the design of the SU-76, which saw its combat debut at Kursk in the summer of 1943. The SU-76 was deployed primarily as an infantry direct support weapon, becoming the infantry tank of the Red Infantry, much as the StuG III became the infantry tank of the German infantry. Featuring full colour artwork and written by an expert on tank warfare during World War II, this fascinating study describes one of the Soviet Union's most important armoured vehicles during its struggle with Nazi Germany.
