The FV 214 Conqueror, also known as “Tank, Heavy No. 1, 120 mm Gun, Conqueror” was a British heavy tank of the post-World War II era. It was developed as a response to the Soviet IS-3 heavy tanks and the Conqueror’s main armament, a L11 120 mm gun, was larger than the 20-pounder (83.8 mm) gun carried by its peer, the Centurion.
