The Cruiser Tank Mk VIII, Cromwell (A27M), and the related Centaur tank, were one of the most successful series of cruiser tanks fielded by Britain in World War II. The Cromwell tank, named after the English Civil War leader Oliver Cromwell, was the first tank in the British arsenal to combine a dual-purpose gun, high speed from the powerful and reliable Meteor engine, and reasonable armour, all in one balanced package. Its design formed the basis of the Comet tank.
The Cromwell first saw action in June 1944, with the reconnaissance regiments of the Royal Armoured Corps.
The Cromwell was the one British tank that saw the most action during the fight with the Race, especially when the Lizards invaded England in 1943. Notability smaller than landcruisers, with a OQF 75 mm gun and 76mm amour, the Cromwell was still able to put up a good fight.
