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.
Sergeant Major is the rank....
CMSgt Chief Master Sergeant is the one after Master Sergeant.
Master Sergeant in the Army is pay grade E8. First Sergeant is the other Army E8 rank.
In the US Army, the next rank above Staff Sergeant would be Sergeant First Class, followed by Master Sergeant and First Sergeant (both grade E8), then by Sergeant Major and Command Sergeant Major (both grade E9). Sergeant Major of the Army is the seniormost noncommissioned officer rank in the US Army. In the US Marine Corps, the next rank above Staff Sergeant (E6) would be Gunnery Sergeant (E7), followed by Master Sergeant and First Sergeant (E8), Master Gunnery Sergeant and Sergeant Major (E9), then Sergeant Major of the Marine Corps. Unlike other military branches of the US Armed Forces, where Staff Sergeant is pay grade E6, Staff Sergeant in the Air Force is pay grade E5 - equivalent to a Sergeant in the Army or Marine Corps. It is followed by Technical Sergeant (E6), Master Sergeant (E7), Senior Master Sergeant (E8), Chief Master Sergeant and Command Chief Master Sergeant (E9), and, finally, Chief Master Sergeant of the Air Force, who - like the Sergeant Major of the Army and the Sergeant Major of the Marine Corps - is the most senior noncommissioned officer in the entire branch. The British, Commonwealth, and some European forces end their enlisted ranks at Staff Sergeant (or equivalent), and rate enlisted personnel senior to Staff/Colour Sergeants as Warrant Officers.
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.
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.

Sergeant First Class is pay grade E7. In the Army, the next pay grade - E8 - has two ranks within it - Master Sergeant, and First Sergeant. The difference being that a First Sergeant is a company's senior NCO, whereas Master Sergeant tends to denote NCOs holding staff positions.
Sergeant, as long as the Sergeant is senior to the one being rated by Date of 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.
