Congratulations on your decision to join up and thanks in advance for your service! (Even tho' it's the Army & I'm retired Navy...it's still "US")
Since you're already online, I'm assuming you know about AKO already? From what I hear all services will be joined soon, if not already started, into DKO.
I'd strongly recommend digging in there and getting a jump start on info gathering. Also MILITARY.COM is a damn good resource too, that site tends to "fill in the gaps"
from what the SECDEF on down deems both official and acceptable.
Two things I always advise potential servicemembers: 1) You're in it for eight years, sometimes recruiters fail to emphasize that, & 2) If it's not written in your contract, it never happened, so whatever signing bonuses, schools,
MOS, duty assignments...whatever your recruiter enticed you with; make damn sure you got it in writing before you sign on the dotted line.
Good luck and again, thanks.
