Marine Corps First Sergeant

First Sergeant is a senior non-commissioned officer’s rank in the United States Marine Corps. A First Sergeant shares the E-8 paygrade with Master Sergeant, although the two ranks have separate spheres of responsibility.

A First Sergeant serves as the senior enlisted advisor to the commander of a medium-to-large unit of Marines, such as a platoon or a company. As the senior enlisted advisor, First Sergeants hold the responsiobility of being the main bridge between enlisted Marines and their company commander. In this position, they serve as advocates for their Marines to the command hierarchy and assist in leading tactical and training operations.

To get promoted to First Sergeant, a Marine (generally holding the rank of Gunnery Sergeant) must receive an outstanding Fitrep (fitness report) from their commanding officer and successfully meet a series of experience and leadership requirements. Before beginning the promotion qualification rounds, the candidate will choose their desired track for promotion - First Sergeant for Marines interested in command responsibility, and Master Sergeant for those interested in technical and operations management.

For First Sergeants continuing on the command track, the next promotable rank is Sergeant Major. The equivalent rank to First Sergeant was established by the Marine Corps back in 1833, and given its modern title in 1872.

First Sergeant is the 9th rank in the United States Marine Corps , ranking above Master Sergeant and directly below Master Gunnery Sergeant. A first sergeant is a Senior Enlisted Advisor at DoD paygrade E-8, with a starting monthly pay of $4,739.
