I find most of the opinions about PTSD are given by people that don't have it. It's like an unskilled laborer telling you how to do your job. I did my full time and only got diagnosed at the very end. Then they said to me "But you've been operating for 30 years like this"...like that was an excuse or a pass. Having a man rattle along isn't the best thing for the situation. By pressing him back into battle, he will likely get killed and then you don't have a problem any more. If he makes it out, things will be much worse.
Anywayzzz, I'm done here. This is one where I feel if you aren't affected and you aren't a Psychiatrist, you don't know. You're just opinionated. And I've heard enough public clap trap about this one.
