The Comet tank or Tank,Cruiser Comet 1 ( A34) was a British cruiser tank that first saw use near the end of WW II. It was designed as an improvement on the earlier Cromwell and mounted the new 77 mm HV gun in a new lower profile and part-cast turret. This gun was effective against late war German tanks, including the Panther at medium range, and occasionally, at close range, the Tiger. The tank was widely respected as one of the best British tanks of the war, and continued in service afterwards.
