Military rank help? What does O-1, O-3, O-10, etc. mean??

Question

What does the O-1 O-2 O-3 O-4, etc mean?

I have a pay chart with years of service and O-1 through O-10. Does O-1 Stand for Second Leutenient and O-2 for First Leutenient and O-3 for Captain?

What do they all stand for?

Answer 1

Yes. Those are the corresponding pay grades.
0-1: 2nd Lt.
0-2: 1st Lt.
0-3: Capt.
0-4: Major
0-5: Lt. Col.
0-6: Col.

and so on.

Answer 2

There's two scales of rank in the military -- the E-# for enlisted and O-# for officers.
An O-6 in the Coast Guard would be equal in rank to an O-6 in the army. Yes, O-1 to O-3 in the army is 2LT, 1LT, and CAPT. In the USCG, its ENS, LTjg and LT. This system's just easier to use when dealing with more than one service, like pay charts.

Answer 3

Depends on the service. O-1 is an Ensign in the Navy, and a Second Lieutenant in the Army. They start at 0-1 and go up from there.

Answer 4

O is for officer and then the number is the pay grade

an easy way to remember (in the AF) is:

21 Captain, My Little Colonel, Be My Little General

2nd LT 1st LT Captain Major LT Colonel
Colonel Brig General Maj General
LT General General

Answer 5

Yes, the O just designates Officer as opposed to E-1 E-2 E-3, which designates Enlisted

Answer 6

e- enlisted o -officer

Answer 7

Well the "O" and "E"s are covered. Now to throw another one in there... "W"s for Warrant Officers. At one time in the Army there were the "SP"s or Specialist Ranks. Which went from SP4 thru SP9. Currently there is only the SP4 left. I think that about covers it for the Army.

Answer 8

This is officers paygrade. Besuide 2nd Lt it also means Ensign for the Navy and Coast Gaurd.

Answer 9

O's are officer ranks, E's are enlisted ranks, and W's are Warrant Officers who are in between.

Answer 10

It depends upon the branch of service.
