My reaction is: oh dear god, don't do it. Do not join the military. Like ever, at any cost.
Back in the day, I had a job interviewing aboriginal veterans (to collect their biographical information), and it was one of the jobs that changed my life. As an outsider to my interview subjects I was told all sorts of disturbing stuff that the veterans had never told anyone, including their children and wives and such. Seeing children and other civilians get shot or meet otherwise violent ends, watching your buddy blow up, having PTSD and/or never ending physical pain... These dudes are tough, and don't generally complain publically or even to their own folks about their experiences, so I would get comments from their kids and wives such as "I never knew that," or "He never told me that" when the articles were published. They would always ask me why the veteran hadn't shared these details and so I started asking veterans this very question and the answer was invariably "I didn't want them to suffer like I did. Suffer knowing ___________ like I do." Holy shit, some of the shit I heard...
Yeah, so my vote is always against anyone joining the military. As noted, there is a reason why the military is always in need of psychologists.
