Probably a lie ...
BUT
If you WERE wounded on a super-duper-top-secret mission, one so SDTS that you just can't talk about it: STFU and don't talk about it.
In NM you must provide a copy of your DD214 and/or DD215 that lists all awards received. Not knowing what GA. requires if anything to claim a PH license plate, I would think some proof is required. Of course you can criminally alter the paperwork, but that opens up a real federal crime can of worms.
