a horizontal axis. Small turns moved the crosstube that carried the front road wheel bogies laterally, warping the track so the vehicle drifted to that side. Further movement of the wheel braked the appropriate track to give a tighter turn. The hull in front of the commander's position jutted forward to give room for the Bren light machine gun (or other armaments) to fire through a simple slit. To either side of the engine was an area in which passengers could ride or stores could be carried. Initially, there were several types of Carrier that varied slightly in design according to their purpose: "Medium Machine Gun Carrier" (the Vickers machine gun), "Bren Gun Carrier", "Scout Carrier" and "Cavalry Carrier". The production of a single model came to be preferred and the Universal design appeared in 1940; this was the most widely produced of the carriers. It differed from the previous models in that the rear section of the body had a rectangular shape, with more space for the crew. Production Production of carriers began in 1934 and ended in 1960. Before the Universal design was introduced, the vehicles were produced by Aveling and Porter, Bedford Vehicles, Ford of Britain, Morris Motors Limited, the Sentinel Waggon Works, and the Thornycroft company. With the introduction of the Universal, production in the UK was undertaken by Aveling-Barford, Ford, Sentinel, Thornycroft, and Wolseley Motors. By 1945 production amounted to approximately 57,000 of all models, including some 2,400 early ones. The Universal Carriers, in different variants, were also produced in allied countries. Ford Motor Company of Canada manufactured about 29,000 vehicles known as the Ford C01UC Universal Carrier. Smaller numbers of them were also produced in Australia (about 5,000), where hulls were made in several places in Victoria and by South Australian Railways workshops in Adelaide, South Australia. About 1,300 were also produced in New Zealand. Universal Carriers were manufactured in the United States of America for allied use with GAE and GAEA V-8 Ford engines. About 20,000 were produced. Operational history The Universal Carrier was ubiquitous in all the theatres during the Second World War with British and Commonwealth armies, from the war in the East to the occupation of Iceland. Although the theory and policy was that the carrier was a "fire power transport" and the crew would dismount to fight, practice differed. It could carry machine guns, anti-tank rifles, mortars, infantrymen, supplies,
