By 1944, the evolution of armoured doctrine had produced very different outcomes in Britain and Germany. Offering a good balance of speed, protection and firepower, the British Cromwell tank was much faster than its German opponent, but the Jagdpanzer IV tank destroyer had a high-velocity main gun and a lower profile that made it formidable on the defensive, especially in ambush situations. The two types would fight in a series of bloody encounters, from the initial days of the struggle for Normandy through to its climax as the Allies sought to trap their opponents in the Falaise Pocket.
