The scout car M1 was based on the Model 12x4 1.5-ton four-wheel drive truck. Pintle mounts for .50cal machine guns were provided just in front of the front passenger door and on the rear of the car, and a .30cal machine gun pintle mount was installed on each rear passenger compartment door. The vehicle was open-topped, and a canvas cover could be installed. The windshield could be protected by a folding armor flap.
