Or both.
If you are E1 after four years, there is no third option. This excerpt from Chief Shipley's video seems to indicate that he was a worthless, no-load shitbird brig rat:
To UA AWOL (Unapproved Abscence AWOL) To Du UTII To Disciplinary unit (Dont know meaning of UTII)
I would say definitely both, mental and a petty criminal. The way he throws his veteran’s status around, I figured he’d washed out of basic, got thrown out on a Section 8, was a problem-child who went to NJP a lot and lived most of his enlistment on Restriction & KP, or was such a loser as a fighting soldier that he got issued a rubber gun and spent his enlistment handing out basketballs at MWR and taking tickets at the base theater. It’s door #2, which is exactly what we all expected.
