Well you share an article that shows the rate of "Deep Mental Disorders" at 100% as you implied it was.
Edit: I also note that you are glossing over literally anything that is an actual response to the OP topic, since I've been including that. Look these guys aren't my "drinking or gym buddies" they're my friends. Like people I've known for years.
Edit 2: And if you were wondering the prevalence for depression in deployed people is 12 percent, which is higher than the national average, but definitely not enough to say that deployments cause depression. I'm sure that we could do the same thing for other disorders. Although many disorders are disqualifying from the military so they'd be more prevalent outside the military.
