No, all the enlisted ranks are under the all officer ranks with regard to chain of command.
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.
Master Sergeant is a rank in the Marines. Master Gunnery Sergeant, Major and Major General are additional Marine ranks.
There has yet to be a female Sergeant Major of the Army.
The lozenge is simply a device to differentiate a First Sergeant from a Master Sergeant, Sergeant Major, etc.
The United States army consists of twelve ranks. They are, in order of rank, Private, Private First Class, Specialist, Corporal, Sergeant. Staff Sergeant, Sergeant First Class, Master Sergeant, First Sergeant, Sergeant Major, Command Sergeant Major, and Sergeant Major of the Army.
Verbal conversations are nearly always General, Colonel, or Lieutenant. Written communications almost always should be Major General, Lieutenant Colonel or 1st Lieutenant.AnswerIn the British Armed Forces, you never address an officer by rank alone. James Bond would never be addressed as "Commander", but as "Commander Bond". Subordinates would never address him by rank; they would simply call him "Sir", never "Commander".
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.
Technically, all officers are of a higher rank than any sergeant. Sergeant Major however, is a very high enlisted rank. A sergeant major will usually only take commands from a Lieutenant Colonel or higher.
When a First Sergeant leaves, it'll either be because they've been relieved of duty, or are about to be promoted to Sergeant Major. Who replaces the First Sergeant depends on the availability. It may be a Master Sergeant transferred from a staff position, or it may be a Sergeant First Class who is about to be promoted to E-8. You won't find Master Sergeants in line companies - Master Sergeants are found in staff positions.

No. Those are 2 different ranks. Master Sgt. is an E-8 while Sgt. Major is an E-9 in pay grade. A master sgt. is next in command before a Sgt. Major if he/she is sick or on vacation but is still addressed by the proper rank he/she wears.
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.
