The ugly (Quote by Sir Winston Churchill) British Churchill (Named after John Churchill, 1st Duke of Marlborough) was a heavy infantry tank that came into service in 1941. It was large, well armed, well protected, and would spawn many Churchill-based variants later in the war. In 1942, six Mk. IIIs were sent to help fight the Germans in North Africa. Armed with 6-pounder main guns, the tanks of "KingForce" were reportedly able to hold out and only sustained minor damage from anti-tank guns. The Mk.III would be later replaced by the more numerous Mk.IV variant, but not before the Mk.III would be credited with capturing the first Tiger tank for the western Allies.
