Throughout the 1930s, a series of production agreements were established for the manufacture, by the Canadian subsidiaries of major American automobile manufacturers, of a line of trucks designed to meet the transport needs of British troops and the principal countries of the Commonwealth. Production was significantly increased during World War II, and the "Canadian Military Pattern (CMP) trucks" accompanied Commonwealth troops on major European fronts, from the North African campaign, to the invasion of Sicily, to the Normandy landing. Robust, reliable, and particularly effective in operational use, they were produced in numerous configurations and with various roles, from military logistics to artillery towing. The CWT 15 version, with four-wheel drive and good load capacity, was particularly appreciated.
