Renault FT (FT-17) Light Tank

The FT-17 was a revolutionary tank that as many as 28 countries used and participated in as many as 10 wars. Its features are still used in modern tanks such as the gun in a rotating turret and the engine at the back.  The FT-17 was, for the most part, copied into other designs such as the Russian T-18, American M1917, Italian FIAT 3000.
