There are little questionnaires(online) throughout the year that might flag someone with any kinds of issues. Obviously, you can easily lie about it, then again so could you hide issues from your doctor. This a whole is a moot point. Culturally, there is awareness that intense situations like combat will mess one up mentally and are generally open to talk to a buddy or seek help. That being said, like Tim Kennedy once said in regards to PTSD and dealing with stress its a world of difference for those who constantly train and deal with certain situations and have the infrastructure in place for them i.e- infantry & other combat arms jobs. Those who are not in those job fields aren't training for it, not mentally prepared, etc but might still be caught up in combat situations. i.e - the water specialist or accountant driving his little truck in Iraq. To add to all this, its usually young men who commit suicide. Its just a thing they do. Which happens to be most of the military.
