The first BA-64s produced were deployed to the Don Front in 1942. However, larger quantities were operated by Soviet units on the Voronezh Front and the Bryansk Front from mid to late 1943. BA-64s also took part in the final phases of the Battle of Stalingrad. During prolonged road marches, Soviet crews retrofitted them with standard tread road wheels to save fuel. BA-64Bs were deployed during Soviet offensives in Austria, Germany, Hungary, and Romania, seeing extensive combat during the Second Battle of Kiev and the Battle of Berlin. Eighty-one BA-64Bs were also donated by the Soviets to the Polish People's Army and ten to the 1st Czechoslovak Army Corps. The Czechoslovak BA-64Bs were used in the Prague Offensive of 1945.
