Marine Corps Special Operations Command (MARSOC) train, organize, equip and deploy task-organized, scalable and responsive Marine Corps special operations elements worldwide in support of combatant commanders and other agencies.

MARSOC is comprised of roughly 2,500 Marines and sailors. The base unit of MARSOC is the fourteen-man Marine Special Operations Team (MSOT). Each 14-man MSOT is organized into three elements: a Headquarters (HQ) and two identical Tactical Elements. The HQ element consists of the Team Leader (Captain), Team Chief (Master Sergeant), Operations Chief (Gunnery Sergeant), and a Communications Chief. Each Tactical Element consists of an Element Leader (Staff Sergeant), three Critical Skills Operators (Sergeant/Corporal), and a Navy Special Amphibious Reconnaissance Corpsman (SARC). MARSOC is based at Camp Lejeune, North Carolina and is split into three subordinate commands.
