The cruiser tank (sometimes called cavalry tank or fast tank) was a British tank concept of the interwar period for tanks designed as modernised armoured and mechanised cavalry, as distinguished from infantry tanks. Cruiser tanks were developed after medium tank designs of the 1930s failed to satisfy the Royal Armoured Corps. The cruiser tank concept was conceived by Giffard Le Quesne Martel, who preferred many small light tanks to swarm an opponent, instead of a few expensive and unsatisfactory medium tanks. "Light" cruiser tanks (for example the Cruiser Mk I) carried less armour and were correspondingly faster, whilst "heavy" cruiser tanks (such as the Cruiser Mk II) had more armour and were slightly slower.
The British cruiser tank series started in 1938 with the A9 and A10 cruiser tanks, followed by the A13, A13 Mark II, the A13 Mark III Covenanter in 1940 and the A15 Crusader which entered service in 1941. The Crusader was superseded by the A27 Cromwell in 1944. The A34 Comet, a better-armed development of Cromwell, began to enter service in late 1944. The Centurion tank of 1946 became the "Universal tank" of the United Kingdom, transcending the cruiser and infantry tank roles and becoming one of the first main battle tanks (MBT).
