BA-20 - Service

Service

The principal use of the BA-20 was as a scout vehicle. The BA-20's tires were designed to be resistant to bullets and shrapnel by the simple expedient of filling them with spongey rubber. A variant, the BA-20ZhD, could travel on railway lines by replacing the normal wheels with flanged metal rail-type wheels.

The vehicle was exported to the Spanish Republican side in the Spanish Civil War, although the vast majority of BA-20s built served with the Soviet Red Army. They first saw combat in the conflict with Japan in 1939 on the Khalkin Gol river in Mongolia (see Battle of Khalkin Gol). The BA-20 was used by the Red Army in the Soviet invasion of Poland later in 1939 and the Winter War against Finland in 1940, as well as the early stages of Operation Barbarossa in 1941. Production was ended that same year, with some 4,800 BA-20s having been constructed by that time. Some had flamethrowers instead of the DP-28.

During the Winter War Finland captured a number of BA-20 armoured cars and put them into service.

In common with most armored cars derived from cars, the BA-20 was largely roadbound. The lack of all-wheel drive, high ground pressure, and low power prevented it from moving cross-country except on very firm ground. The armor was too thin to stop anything other than fragments or small-arms fire, and the 7.62 mm machinegun was not adequate to penetrate other scout vehicles. The Red Army produced very few wheeled armored fighting vehicles in the war, but replaced the BA-20 with the BA-64B.
