Just so you have a reference point.
Marine ranks are EXACTLY the same as Army ranks, whereas Navy and Air Force are different.
I may make a couple of mistakes, but I'm trying to remember the rank structure from a military I didn't serve in.
From lowest to highest.
Non-comissioned members:
Recruit.
Private.
Private 1st Class.
Specialist.
Corporal.
Sergeant.
Sergeant First Class.
Technical Sergeant.
Gunnery Sergeant.
Another Sergeant rank.
Master Sergeant.
Sergeant Major.
Command Sergeant Major, highest ranking NCM.
As for Officers.
Officer Candidate(student officer, still in Officer Candidate School).
Second Lieutenant.
First Lieutenant.
Captain.
Major.
Lieutenant Colonel.
Colonel.
Brigadier General.
Major General.
Lieutenant General.
General.
The "Big Cheese", for the USMC is Commandant, for the Canadian Forces he's the "Chief of Defense Staff".
The ranks for helicopter pilots in the Marine Corps and the Army are a bit different.
Instead of Sergeants, they have Warrant Officer, Chief Warrant Officer, and Master Warrant Officer.
They do have officers as helo pilots, but that's because those individuals went to OCS, whereas the Warrant Officers didn't, the WO's only had to pass flight training.
If a Marine Captain is on board a non-USMC ship, he's given a temporary promotion to Major, as by Maritime tradition, there can be only 1 "Captain" on the vessel.
Navy ranks are a bit weird, they've got:
Lieutenant, Junior Grade.
Lieutenant.
Lieutenant Commander.
Commander.
Captain.
"something" Captain.
Then there's 3 different Admiral ranks.
And Commodore.
The top guy is "Admiral".
The Non-commissioned, if I remember correctly, start with:
Ordinary Seaman.
Able Seaman.
Leading Seaman.
Then there's ranks like "Boatswain", "Coxswain", and several others.
Plus, you have to keep in mind the seniority and the duties of the different officers.
I won't even think about typing out the ranks for the Air Force, because I don't remember them.
If anyone is interested, I can type up the ranks for the Canadian Forces, Land (commonly referred to as the Canadian Army).
I might even have the rank structures for the USSR, FRG, DDR, AIR, the British Army and Royal Marines, oh, and don't forget France, Belgium, Greece, Spain, and Turkey.
I'm joking, by the way.
While I may still have that data, I'm not "flaky" enough to actually go dig it out and actually type it out.
Later.
