He thought he would be a really good Drill Sergeant
The possessive form of "sergeant at arms" is "sergeant at arms'." If referring to a single sergeant at arms, you would say "the sergeant at arms' duties." If you need to indicate possession by multiple sergeants at arms, you would use "sergeants at arms'."
Drill Sergeant wanted to send Gump to OCS, Officer Candidate School, but according to him it would have been a waste of an inlisted man.

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.
The '3' indicates skill level 3, which would be the rank of Staff Sergeant. A Staff Sergeant would be a squad leader, or a Staff Sergeant with seniority or who is close to promotion to Sergeant First Class might fill the role of Platoon Sergeant. They might also work as a staff NCO in a battalion/brigade/division/etc. shop, which wouldn't be a leadership position.
Master Sergeant is a military or police rank. It has no gender and would be applied to anyone at that level, regardless of their sex.
The question makes no sense. There is no such thing as a "Marine Second Sergeant" (nor would one be in the Army if such a thing existed), nor does even a "Second Sergeant" rank exist.
A Sergeant in the police force would be a first line supervisor of those below them, yes.
