This seems like outrageous bigotry. If he made it thru a war, how could ptsd possibly make him unfit for firefighting?

You might have answered the questions dfferently. Next time, less aggression-it's a trick anyway. They are not looking really for whether you are stable but how you react to someone cutting to close to a vulnerable area of your life-it's a way of weeding out candidates even if they don't need to do so. Next time just say that the military wants to ensure everyone who has gone thru a firefight is fit to must back into duty, and so you went thru the motions until they did-no big deal at all, just routine bueracratic stuff.
