The Dodge M37 (G-741) was a three-quarter ton four-wheel drive truck. It superseded the Dodge WC-51, WC-52 and WC-54 trucks in US service and was used extensively by the United States armed forces during the Korean War. A number of variants were produced with slightly different configurations: the M42 command truck, V41 telephone maintenance vehicle, M43 ambulance, M152 enclosed utility truck, and R2 air field fire engine.
