Sergeant Major of the Marine Corps

Sergeant Major of the Marine Corps is the most senior enlisted rank in the United States Marine Corps and serves as the principal advisor to the Commandant of the Marine Corps on matters concerning the enlisted force. The position was formally established in 1957 to provide a direct, institutional link between the highest levels of Marine Corps leadership and its non-commissioned officers and Marines.

History and establishment

The role evolved from earlier positions like the Sergeant Major of the Marine Barracks, Washington, D.C., which held significant prestige but was limited in scope. Following World War II and the Korean War, the growing complexity of the Corps and the need for a centralized enlisted voice at headquarters led to its creation. The position was officially established on 23 May 1957, by General Randolph M. Pate, the 21st Commandant of the Marine Corps. The first appointed to the role was Sergeant Major Wilbur Bestwick, a veteran of campaigns in World War II and the Korean War. This institutionalization mirrored similar developments in other services, such as the creation of the Sergeant Major of the Army.
