The 75 mm Howitzer Motor Carriage M8, sometimes known as the M8 Scott, was a self-propelled howitzer vehicle of the United States developed during the Second World War.

It was developed on the chassis of the then-new Light Tank M5 (Stuart VI). The test vehicle had the standard M5 turret removed, and replaced with an open topped turret, this vehicle was designated the T17E1 HMC[1].
Armament consisted of a new open topped turret armed with a 75 mm M2 howitzer, later an 75 mm M3 howitzer, which were reworks of the M1A1 pack howitzer. It carried 46 rounds of 75 mm ammunition; types of ammunition carried were Smoke M89 and H.E. (High Explosive) M48. It featured no coaxial or hull mounted Browning M1919A4 .30-06 machine guns as featured on standard Light Tank M5s. The only other armament was Browning M2HB .50-caliber machine gun for local area, and anti-aircraft defense; 400 rounds of .50-caliber were stowed onboard for the M2HB.
The T17E1 HMC was ordered into production as the 75 mm Howitzer Motor Carriage M8 in April 1942. Production ran from September 1942, to January 1944. A total of 1,778 vehicles were produced.
The M8 saw action in the Italian Campaign, the Western Front, and in the Pacific Theater of Operations during the war. It was used by the French Union and State of Vietnam during the First Indochina War. It was largely replaced by the adaption of the M4 Sherman to use the 105 mm howitzer.
