The British Army made extensive use of a variety of military vehicles during the Second World War. Front lines could only advance with secure supply lines behind them and wide array of transport vehicles was necessary to bring the needed supplies to the advancing fronts. Bedford Vehicles in particular made a large contribution to the country's war effort - their MW 15cwt truck (66,000) and QL 3-ton lorry (52,000) were two of the most numerous British vehicles during the Second World War. Armoured cars were lightly armed and wheeled, often used as command or reconnaissance vehicles, though they saw their share of combat. Vehicles of other classifications, whether tractors, motorcycles, or other types, contributed to the war as much as their higher-profile siblings.
