Lololol, only 5 enlisted ranks in the Army?  I love how you include basically all 9 enlisted ranks for the Navy, but not the Army.  I understand this isn't meant to conform to modern military structure, but I'd at least throw in Sergeant (before SSgt), Master Sergeant, and Sergeant Major.  Also, if you're going to have a Lieutenant Colonel but not a Colonel, then I would suggest it just be replaced with Colonel.

Also, if it helps any, modern Air Force ranks are as follows:

Enlisted:
-Airman Basic (AB)
-Airman (AMN)
-Airman First Class (A1C)
-Senior Airman (SRA)
-Staff Sergeant (SSGT)
-Technical Sergeant (TSGT)
-Master Sergeant (MSGT)
-Senior Master Sergeant (SMSGT)
-Chief Master Sergeant (CMSGT)

Officer:
-Second Lieutenant (2LT)
-First Lieutenant (1LT)
-Captain (CAPT)
-Major (MAJ)
-Lieutenant Colonel (LTCOL)
-Colonel (COL)
-Brigadier General (BGEN)
-Major General (MGEN)
-Lieutenant General (LGEN)
-General (GEN)

Sorry to get picky about semantics.  Being in the military, I can't help but nitpick that shit.  Otherwise, I am quite interested in this RP, and I am also more than happy to further advise on military information.
