BA-3, BA-6, BA-10, BA-10M Armoured Cars

During the late 1930s, Soviet armoured fighting vehicle designers incorporated sloped armor into all their new designs, and redesigned some existing vehicles to take advantage of it. The BA-10 used a slightly smaller, better-sloped armor layout than that of the BA-6, thus improving protection while saving weight. The greater engine power (50 hp, compared to 40 hp on the BA-6) made the vehicle more reliable.

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. On early BA-10s, these tracks were stowed strapped on top of the fenders. Later vehicles had an enclosed stowage box for the tracks in the same location. The tracks were often fitted when the vehicle needed to move across snow or soft ground.
