The 75 mm Gun Motor Carriage M3 was a United States tank destroyer and self-propelled artillery piece of the World War II
About this creation
The M3 Halftrack Gun Motor Carriage was the most prolific tank destroyer in service with the US Army, participating in critical battles in North Africa and the Philippines, and continued to be used in more limited numbers in Sicily, before being declared obsolete in early 1944.
The 75 mm GMC M3 was an M3 Halftrack with an M1897A4 75 mm gun mounted in the rear of the halftrack. The gun had an indirect fire range of 8,400m and fired an armor-piercing shell that could penetrate 8.1 cm of armor at 460m and the HE M48 (High Explosive) shell for use against infantry and other non-armored targets. The M3 carried 59 rounds of 75 mm ammunition onboard. The crewmen were equipped with a rifle and four carbines for self defense.
Although then considered obsolete for use against German tanks, the M3 was powerful enough to destroy the light tanks deployed by the Japanese, and so the M3 continued to be used in the Pacific Theater, primarily with regimental weapons companies of the USMC, seeing action on Saipan, Peleliu, and Okinawa, among other island battles.
