Section 8 (military)
The term Section 8 refers to a category of discharge from the United States military for reason of being mentally unfit for service. It also came to mean any serviceperson given such a discharge or behaving as if deserving such a discharge (as in the sentence "He's a Section 8"). The term comes from Section VIII of the World War II-era United States Army Regulation 615-360, which provided for the discharge of those deemed unfit for military service.
Just food for thought!
