The Canadian Military Pattern (CMP) truck was a class of military truck - of various forms - made in large numbers in Canada during World War II to British Army specifications for use in the armies of the British Commonwealth allies.
The Chevrolet-built CMP trucks had a 215 cu in (3.5 L), 85 bhp overhead-valve engine. An American-made 270 cu in (4.4 L) GMC straight-6 engine powered the 3-ton truck.
