No, the form does not list a reason. Nor does it list his rank, place and date of birth. It's as plain of a form as one can get. It's nothing like the DD214 that I have for my service, and I only have one.
I contacted my congress critter. Guess I'll see what he can do, if anything.
Thanks.
Remember, it the house of rep critter doesn’t respond, write to the senators.
