Car, Scout, 4x4, M-3A1 (G-67)
The 4x4 chassis of the M3A1 Scout Car supports an armored box body made of 1/4 inch steel plates. A protective shield of 1/2-inch armor plate can be lowered over the windshield. Adjustable steel louvers protect the radiator when lowered. The front mounted anti-ditching roller enables the M3A1 Scout Car to extract itself from a trench.
The M3A1 Scout Car was typically armed with two machine guns (one M1917 .30 cal. and one M2 HB .50 cal.) that attached to the skate rail that went fully around the inside of the rear compartment. One or more .45 cal. submachine guns were provided for crew defense.
Nearly 21,000 of the M3A1 Scout Cars were produced during 1940-1944. White built the chassis while Diebold Safe & Lock provided the armored body. The M3A1 was popular for its mobility and flexible deployment possibilities, but the open top design made the crew too vulnerable on the battlefield and the off-road mobility suffered in comparison to tracked vehicles.
