The GMC CCKW is a 2½ ton 6X6 U.S. Army cargo truck that saw service in World War II and the Korean War, often referred to as a "Deuce and a Half" or "Jimmy". The CCKW came in many variants, the simplest being open or closed cab, and Long Wheel Base (LWB 353) or Short Wheel Base (SWB 352).


Convoy Red Ball Express

CCKWs in Red Ball Express convoy, 1944

Built to 812,262 copies, CCKWs were employed in large numbers for the Red Ball Express, an enormous convoy system created by Allied forces to supply their forces moving through Europe following the breakout from the D-Day beaches in Normandy, from August 25 to November 16, 1944, when the port facilities at Antwerp were opened.[1] At its peak the Red Ball operated 5,958 vehicles, and carried about 12,500 tons of supplies a day.[2]

The designation CCKW comes from model nomenclature used by GMC; the first C indicated a vehicle designed in 1941, the second C signified a conventional cab, the K indicated all-wheel drive and the W indicated winch for the version with the winch on the front. The term "Deuce and a Half" is not a post war term and was applied to all 2½ ton cargo trucks.
