A development of the British Vickers 6-ton light tank the Polish 7TP saw combat in the Defence of Poland in 1939. Although significantly better armed than the German’s Panzer I and Panzer II the 7TP was never fielded in enough numbers to change the outcome of the war – indeed there were only ever 108 of the single turret versions in Polish service.

The 7TP designation meant “7 Tonne, Polish” although the final version weighed in at 9.9 tonnes.
