Master Sergeant in the Army is pay grade E8. First Sergeant is the other Army E8 rank.
I assume you are talking about E-8 and E-9 ranks. At E-8 you become either a First Sergeant or a Master Sergeant. If you take the First Sergeant route the next rank becomes Sergeant Major. If you take the Master Sergeant route the next rank becomes Master Gunnery Sergeant.
YES
Sergeant is the higher rank.
The Army and Marines both have two ranks in the E8 pay grade - Master Sergeant, and First Sergeant. There is one E8 rank in the Air Force - Chief Master Sergeant. If they hold the position of First Sergeant, they get a diamond on their rank insignia to denote it, but their rank remains Chief Master Sergeant.
In the United States Army, the rank of First Sergeant (abbreviated as 1SG) is above Sergeant First Class, below the ranks of Sergeants Major and shares the paygrade of E-8 with Master Sergeant. The rank of First Sergeant carries more responsibility than the rank of Master Sergeant, and the rank may be either given to the soldier upon promotion to the paygrade of E-8 or they may be "laterally promoted" (promoted in rank but not paygrade) from Master Sergeant at a later date. They are also known unofficially as Top Sergeant or just Top, due to the fact that First Sergeants are the most senior non-commissioned officers in an Army company. Right - that is Current, but what was the difference during World War II, when Master Sergeant was technically higher than First Sergeant (Although both E-7)? - Master Sergeants were higher in responsibility than FSgt's. Master Sergeants were commonly Battalion level NCO's during WWII, also more experienced members of the Armored and Air Corps. First Sergeant was the most senior NCO positions in a Company.
A Senior Master Sergeant is ranked above a Master Sergeant in the United States Air Force and the United States Space Force. It is the eighth enlisted rank in the Air Force and the Space Force, equivalent to a First Sergeant in the Army and Marine Corps or a Senior Chief Petty Officer in the Navy and Coast Guard.
