Congrats, Eric. What job did you get (or you have now?) I never heard you mention that piece of the puzzle before.
FYI:
Grade equivalents are generally considered the following:
Full Colonel (O-6) = GS-15
Lt Colonel (O-5) = GS-14
Major (O-4) = GS-13
Captain (O-3) = GS-12
1Lt (O-2) = GS-11
2Lt (O-1) = GS-10
Pay varies but the general pay table before local increases can be found at:
