As far as suicides go, I'm coming up with 268 total in 2010--that includes US Army active duty, reserve and national guard, out of a approximate total strength of 1,125,600. The US national suicide rate was something like 19 suicides for every 100,000 citizens. My math sucks so don't hold me to this but as near as I can figure the Army in 2010 was looking at roughly 23 suicides per 100,000. So it's higher than the national average but given the nature of military life, the danger, the long periods of deployment, multiple deployments, changing rotation dates, stop-loss, the proximity of firearms and factors that make military life different and more difficult than civilian life, the figures--if correct--aren't really surprising.
I had a pretty good view of what happened to the US military in the decade after Vietnam and the situation now would have to really go to hell for it to get anywhere near that kind of crisis. I just can't see much reason for alarm now. Some of this sounds like normal post-conflict force-reduction ebb and flow.
When we cut back we lose good people. Not all deserving Lieutenants will be on the promotion list for Captain.
