October 1966 — Vietnam. U.S. Marines unleash the devastating power of the M2 .50 caliber machine gun—the legendary “Ma Deuce.” Already a veteran of World War II and Korea, this heavy machine gun remained the undisputed king of the battlefield. In Vietnam’s jungles, firebases, and convoys, its deep, steady thump meant one thing — security. Whether defending a perimeter, protecting a supply route, or breaking an enemy assault, when all else failed, Ma Deuce never did. #vietnamwar #madeuce #m2brown
