I'm an ANG O-3 with an effective date to promote to O-4 of 1 October...today (via ROPMA board). My MPS has not yet received the federal order and says that I cannot pin on until it's received. Last week I submitted a myPers ticket asking for my order. The response was to ask my MPS for it ... and that "you don't need a promotion order for a promotion ceremony." I can't find that in an ANGI/AFI anywhere, nor do I know why it's taking so long to receive the order. Anyone care to take a stab at why and how one wouldn't need the order to pin on...and why it would be taking longer than the prescribed "NLT 2 weeks prior to effective date"?
