A semi-amphibious American Military ¼-ton 4x4 tactical vehicle designated M422-A1 by the US Marine Corp. It is made of aluminum over a steel frame truck, suitable for airlifting and popular during the 1960's.

The Mighty Mite remains a rare vehicle today as collectors particularly like its independent suspension all around (front: leading arms/trailing arms rear), sprung ¼-elliptical leaf springs. Among the M422's many other unique features are front and rear Posi-Traction differentials, inboard differential mounted drum brakes, center-point steering and the aluminum V4 engine developed by American Motors. The air-cooled 108 cu in (1.8 L) developed 52 bhp (39 kW) and 90 lb·ft (122 N·m) of torque, which propelled it to a top speed of 65 miles per hour (108 km/h), with a 55-mile-per-hour (89 km/h) military rating.
