who is a dirtier sob, a master sergeant or a first sergeant?
I am a civilian and have no idea, but it seems like after you reach gunnery sergeant the rank splits off. Why the split? How does the job they do define what they will become as a senior enlisted staff nco? I think master sergeants got more balls then first sergeants, but that’s just me. Open to any comments negative or positive, just be motivated.
Answer: “First Sergeant have a command responsibility while Master Sergeants have technical responsibilities.”
In the United States Marine Corps, First Sergeant is one level below Sergeant Major and Master Gunnery Sergeant and is the next rank above Gunnery Sergeant. It is equal in grade to Master Sergeant, although the two ranks have different responsibilities. First Sergeant have a command responsibility while Master Sergeants have technical responsibilities. Unlike the First Sergeant and Master Sergeant programs in the U.S. Army, no lateral movement is possible between the two ranks in the Marine Corps. In the Marine Corps, when a Gunnery Sergeant gets promoted to First Sergeant, his MOS automatically is re-designated as “8999″. In their annual performance evaluations, called “fitness reports”, eligible Gunnery Sergeants indicate whether they wish to be considered for promotion to Master Sergeant or First Sergeant. A First Sergeant is then eligible to be promoted to a Sergeant Major while a Master Sergeant would be on the promotional track for Master Gunnery Sergeant.
