From Dennis Oliver’s Introduction,
"The American-build M4 Medium Tank, christened Sherman by the British, served in every theater of war from North Africa, Sicily and Italy to north-western Europe and finally in the Far East. From late 1942 it was arguably the most important armoured vehicle in Britain’s arsenal, with the possible exception of the Churchill. Field Marshal Montgomery, the overall commander of the British and Commonwealth units fighting in the Mediterranean and later in Normandy, considered the Sherman to be a universal tank, capable of both close infantry support and mobile warfare."
