The Mack armored car, based on Mack's AB 2-ton truck, was privately financed for the New York National Guard along with two similar vehicles, one based on Locomobile's 6-cylinder 48 hp truck and the other on a White truck chassis. The White vehicle also used a 4-cylinder engine, weighed 8,690lb (3,940kg), and could travel at 30mph (50kph). The open-topped armored bodies were essentially identical, and a machine gun could be mounted on each side of the vehicle near the opposite corners of the rear compartment. The gunners were protected by shields, though these were noted as "barbettes" in contemporary sketches. The engine radiator grilles of the vehicles took different shapes throughout their lives in response to cooling requirements, and were sometimes made of sheet metal. All three vehicles saw service along the Mexican border in the mid-late 1910s, but none saw actual combat.
