The Tank, Cruiser, Mk VI or A15 Crusader was one of the primary British cruiser tanks of the early part Second World War and perhaps the most important British tank of the North African Campaign. The Crusader's mobility made it a favourite of British tank crews and its Ordnance QF 6 pounder main gun made it more than a match for the early Panzer III and Panzer IV tanks it faced in combat. Retained in service because of delays with its replacement, by late 1942 the lack of armament upgrade combined with the presence of Tiger I Tanks among the Afrika Korps and overheating problems caused by the high temperatures of the desert, led to the design being phased out in favour of the new US-supplied Sherman medium tank. The next British cruiser in combat would be the Cromwell heavy cruiser.
Crusader II (Cruiser Mk VIA) The Crusader II had increased armour on hull front and turret front. As with the Mk I, the auxiliary turret was often removed.
