The Sexton was a Canadian 87.6mm self-propelled gun widely fielded by the Allied forces in every theater of operations of World War II. In service between 1943 and 1956, it was also employed by Canadian forces in the Korean War. The Sexton was first used in combat by the British Eighth Army in September 1943, during the Allied invasion of Italy. Tactically, it was massively used to provide concentrated, indirect fire support to frontline ground forces. The Canadians manufactured approximately 3,200 Sextons between 1943 and 1945 in two versions: Mark I and Mark II, with the former variant being fielded by the Canadians forces and the latter one by the British.
Technically, the Sexton was a British QF 25 pounder field howitzer fitted on the Ram and Grizzly (M4) tanks chassis. It was roofless and the 6-man crew had no upper armor protection. The Canadian version used the Ram tank chassis, and the British variant employed the latter tank chassis. This self-propelled howitzer fired 11.5-kg High Explosive shells and had a maximum range of 8 miles (12.25 km). The vehicle, on which this artillery piece was mounted, was powered by one Continental R-975 9-Cylinder gasoline engine, that delivered 400 horsepower. It had a maximum road speed of 25 miles per hour (40 km/h) and a range of 125 miles (210 km).
