Lla GMC CCKW était 21/2-tonne 6×6 Camion cargo de l’armée américaine qui a vu le service lourd dans la Seconde Guerre mondiale et la guerre de Corée. L’original « Deuce et demi », it formed the backbone of the famed Red Ball Express that kept Allied armies supplied as they pushed eastward after the Normandy invasion.
The CCKW came in many variants, including open or closed cab, long wheel base (LWB 353) and short (SWB 352), and over a score of specialized models. It began to be phased out with the deployment of the 6×6 M35 in 1950, but remained in active U.S. service until the mid-1960s. It is related to the Chevrolet G506, built at the same factory.
