The M8 Greyhound is a Reconnaissance Vehicle, a light armoured car developed by the United States during the Second World War and used for scouting and screening. Based on the M8 light armoured car chassis, it combined good road speed with a 37 mm gun capable of engaging light armour and infantry. The 7.9-tonne wheeled vehicle is crewed by four — driver, gunner, commander, and one passenger — and is powered by a Hercules JXD petrol engine producing 110 hp for 13.9 hp/t and a top speed of 90 km/h.
Main armament is the 37mm M6 cannon with coaxial .30 cal M1919 machine gun; the commander's cupola mounts a stabilized 12.7mm M2. The gunner has a 3x telescope sight with no rangefinder. Light armour and high mobility suited the Greyhound to hit-and-run and reconnaissance rather than sustained combat.
