The United States Marine Corps Silent Drill Platoon is a 24-man rifle platoon led by a Captain and Platoon Sergeant of the United States Marine Corps (USMC).

Often referred to as The Marching Twenty-Four, the unit performs a unique silent precision exhibition drill. The purpose of the platoon is to exemplify the discipline and professionalism of the Marine Corps. The Silent Drill Platoon, which first performed in 1948, originally as a one-time show, received such an overwhelming response that it soon became part of the routine parades at Marine Barracks, Washington, D.C. The Marines selected must be male and must be between 5'11" and 6'1" (180.3 and 185.4 cm) tall and be in the median of their weight requirements for their height. Uniformity is a key asset.
