There's some research indicating that being around people who have shared similar experience matters a lot. Basically, it's not trauma if it happens to a big enough % of people. It's just a normal (if unlucky) life experience. When the British went and whacked Argentina they found that the soldiers who hopped on a plane and 12hr later were surrounded by people who will never have to make a life and death decision and are complaining about how they "literally got ptsd" from firing a rifle had PTSD type problems at a much higher rate than soldiers who got a 2wk boat ride surrounded by people who had been through the same stuff.
