The early-1940s terminology situation is summed up in the definition given in "Words of the Fighting Forces" by Clinton A. Sanders, a dictionary of military slang, published in 1942, in the Pentagon library: "Jeep: A four-wheel drive car of one-half to one-and-one-half-ton capacity for reconnaissance or other army duty. A term applied to the bantam-cars, and occasionally to other motor vehicles (U.S.A.) in the Air Corps, the Link Trainer; in the armored forces, the ton command car. Also referred to as 'any small plane, helicopter, or gadget'". "Jeep" could still mean various things, including light wheeled utility vehicles other than the jeep.
