About the M3 75mm GMC – Self-Propelled Tank Destroyer

The halftrack truck is a ubiquitous design that was found in common use by Allied and Axis armies during World War II. It blended the best aspects of both a truck and tracked vehicle. It maintained the all-terrain capability of a tractor, but the speed and ease of manufacture of a heavy-duty truck. The result is something quite interesting. Originally designed by United States Army to support artillery units, the halftracks found use by cavalry and armored units. These vehicles were themselves lightly armored and armed with Browning M2 .50 caliber machine guns and M1919 .30 caliber machine guns. The halftracks proved decisive in many engagements in North Africa, Italy, and the European front. While many were used as troop transports, a few were transformed into something with a bit more punch.

The M3 Gun Motor Carriage (GMC) was built in response to the United States Army’s need for a self-propelled anti-tank weapon to go toe-to-toe with German tanks and offer greater lethality to mobile infantry units. The halftrack was eventually eclipsed by dedicated tank destroyers—such as the M10 and M18—but early in the war, especially in the North African campaign, the GMC was prominent and deadly. For the main gun, the M1897A4 105mm cannon was modified and placed in the bed of the halftrack. A shield surrounded the gun to offer protection for the gunner’s crew, but it was sometimes removed to save weight and increase speed. Special ammunition was built to better service the gun in its tank hunting role. The M61 ammunition was armor piercing up to three inches at 1,000 yards. This proved useful against early war German Tanks, but by the end of 1943, the gun was ineffective. Nearly 59 rounds were stored in the truck along with a crew of five for it to operate effectively. Over 2,092 halftracks were converted to the GMC variant and saw service around the world by U.S. and Allied nations. As the German Tanks grew and stature, many of the tank-hunting halftracks were shipped off to the Pacific theater and served in the campaigns against Japan where they were extremely effective against the thin-skinned Japanese tanks. However, by the end of the war, many were retired along with other tank destroyers as the United States shifted to the Main Battle Tank ideology.
