The M8 (HMC) was a self-propelled howitzer built using the M5 light tank series chassis. Produced by the Cadillac division of General Motors, the M8 (HMC) was armed with a 75mm Howitzer M2/M3 mounted in an open topped turret and was designed for use as a close support weapon.
The M8 was used against fortified enemy positions and, because of its high elevation turret, was good at hitting the enemy on sides of hills.
The M8 (HMC) saw service with the U.S. Army in Europe and Pacific during WWII. It was also provided to the French who used them in Europe and post-war Indochina and Algeria.
