What is the senior enlisted adviser to the Commandant called?

• A. The Sergeant Major of the Marine Corps.
• B. The Master Gunnery Sergeant.
• C. The Chief Petty Officer.
• D. The Senior Enlisted Advisor to the Commandant (fictional).

Answer: (A)

The Sergeant Major of the Marine Corps serves as the senior enlisted adviser to the Commandant. This is a unique billet at the very top of the Marine Corps’ enlisted leadership, appointing a single person who acts as the primary advisor on matters affecting enlisted Marines, including morale, welfare, training, and policy across the entire Corps. A Master Gunnery Sergeant is a high enlisted rank, but it is not the specific advisory post to the Commandant. The Chief Petty Officer is a Navy rank and not part of the Marine Corps. The idea of a fictional Senior Enlisted Advisor to the Commandant doesn’t reflect the real Marine Corps structure.
