The Churchill MkIII was a British Infantry Tank in World War 2, and was used across all of the Allied areas of operations, including as lend lease tanks in Russia. Armed with the 6 pounder gun, it was an effective tank, and was heavily armoured, though slow. 626 were built.
NOTE: The MkIV Churchill was almost identical to the MkIII, and over 1000 were produced. This model can be used as either mark.
