I wondered about that. Perhaps the forger couldn't find the old address (presumably not a facility on an AFB or Federal land) so they whipped up something.
"You did what? I hadn't found the actual address yet, so I just typed in a fake PO box as a placeholder. You weren't supposed to give those papers to them yet, you dumb****. This was supposed to be the approval phase, not the release phase."
"Oh."
