 Greater Sherman production and availability meant that the Ram was never used in action as a gun tank, being either used for training or converted to Kangaroo armoured personnel carriers.A later Canadian medium tank, produced from late 1943, was the Grizzly, an adaption of the Sherman M4A1.This differed only in details, such as the CDP tracks, British radio equipment and the British 2" smoke mortar in the turret roof.
