Basic training was the easiest part of my military career. The recruits that went home did so because they got hypothermia or cracked the tops of their humerus, not because they couldn’t hack it mentally. If they wanted to weed out those unfit, then the individual who this article is about would be disqualified or an RTT in basic. I was discharged at the end of my contract because of physical injuries, so I understand being considered unqualified for military service.
I cannot think of any reason I wouldn’t defend my home, friends, and family against a foreign invader. If the US was being invaded and my family’s lives were at risk, you can bet your ass I’d be doing everything I could to defend my country.
