Historical Review...

The tank was developed building on the experience of use of the previous models of the BT-series tanks. Main emphasis was on improvement of the reliability, ease of manufacture as well as on enhancement of the COMBAT CHARACTERISTICS. The BT-7 was the most well-developed of the BT series tanks. The tank was used in local military conflicts of the 1930s and in the Second World War. Total production of the BT-7 was 4,965 vehicles. The work on improvement of the BT series tanks was carried out under the leadership of A.O. Firsov.
