Soviet Planners Didn't Expect the Conqueror's 120mm to Outrange the IS-3 So Far

When the IS-3 rolled past Field Marshal Montgomery at Berlin's 1945 Victory Parade, British intelligence realised the Centurion was already outclassed. The answer was the Conqueror — sixty-five tonnes, a 120-millimetre L1 gun, and a Fire Control Turret that gave commanders an unprecedented edge over Soviet heavy armour. This is the story of how a bankrupt Britain built NATO's heaviest gun tank, outranged Soviet heavies on the North German Plain, and quietly rewrote Cold War armoured doctrine.
