The Otter Light Reconnaissance Car was a light armored car produced by General Motors Canada during the Second World War for British and Commonwealth. The Otter was based on the Chevrolet C15 Canadian Military Pattern truck chassis and used many standard GM components. The armament consisted of a hull-mounted Boys anti-tank rifle and a Bren light machine gun in a small open-topped turret. Between 1942 and 1945, 1761 units were produced in Oshawa, Ontario. The Otter served with Canadian units in the Italian Campaign and Northwest European operations. It was also employed by the Polish, Czechoslovakian and South African units and the British RAF Regiment.
