The BA-10 (Broneavtomobil 10) was an armored car developed in the Soviet Union in 1938 and produced until 1941. It was the most produced Soviet pre-1941 heavy armored car – With 3,311 built in three versions. These were the BA-10, the BA-10M (improved version with new radio), and the BA-10ZhD (equipped for dual railway/road use). The basic BA-10 design was developed from the BA-3 and BA-6 heavy armored cars. It had an improved GAZ-AAA chassis and improved armor. Like its predecessors, the BA-10 could be converted to a half-track by fitting auxiliary tracks to the rear pair of dual tandem wheels. These tracks were often fitted when the vehicle needed to move across snow or soft ground.
The BA-10 first saw action against the Japanese in Manchuria at the Battle of Khalkhin Gol in 1939. Some were captured and later used by the Manchukuo. It was involved in all the Soviet Union’s subsequent military operations and campaigns of 1939-1940. During World War II the BA-10 was used against the Germans on the Eastern Front, but was rarely seen after the winter of 1941–42. Later in the war the heavy scouting role was taken over by light tanks such as the T-60 and T-70. A few BA-10s were seen as late as 1943 on the Leningrad front. Large numbers of captured BA-10s were used by Axis powers in Europe. In May 1945 a few BA-10s of ROA fought alongside the defenders of the Prague uprising. The BA-10 was in Red Army service until 1945.
