Depending on when he was discharged. A guy I went to high school with had a section 8 discharge. At the time I had been looking into joining the military. The recruiter is the one that told me the guy I went to school with had a section 8 discharge. The guy was gay. This would have been late 70’s early 80’s, do I don’t know when DADT came about. Just tossing it out there and another possible non physical disability, though it could certainly fall into mental.
I suppose in the 70’s that might come under mental. You’d think that being a leftist, he’d be proud to say it, the gay discharge.
