The Red Army met the Great Patriotic War without self-propelled artillery installations in its armament. But already in late July 1941, the first ZIS-ZO self-propelled guns began arriving in units—though only 100 were produced. In late 1942, the Red Army received its first assault self-propelled guns, the SU-122, and in 1943 the light SU-76 self-propelled gun started to be delivered to units. In total, more than 25,000 self-propelled artillery installations fought on the fronts of the Great Patriotic War, earning themselves an undying glory. The difficult service of these self-propelled guns is described by the heroes of the new book from the project “I Remember” (http://iremeber.ru)—veterans of self-propelled units.
