Development history

The BT-5 married the Christie chassis to the 45 mm 20-K gun in a new cylindrical two-man turret, making it genuinely dangerous to 1930s armour. Soviet BT-5s fought for the Republic in Spain, took part in the Khalkhin Gol battles against Japan where their speed was decisive in encirclement, and were still in service in 1941. Their weakness was petrol fires and thin armour - lessons that fed directly into the diesel, sloped-armour T-34.
