There are about 25 things wrong with the memo, but this isn't one of them-- the PO Box is 100% legit. Numerous threads on this point from a couple of days ago. (On the other hand, it was still almost unheard of to USE a PO Box in a military document rather than the physical address.)

Unheard of or not, that is what they did. President Bush's "Suspension From Flying Status" clearly bears the P.O. Box number "34567". Of course it also bears the DOD seal, and is from the Headquarters 147th Fighter Group (ANG) on real letterhead. I have yet to see real letterhead for the 111th. Has anyone?
