You'd be suprised at how many claiming PTSD spent the war riding a desk. In modern combat maybe 10 percent actually get shot at. A lot of this is just a play for attention and money. I know out of all the Vietnam Vets I have known none fit the stereotypical bum in camouflage pissing and moaning about the VA description.
There are people with PTSD who were not in combat. The female nurse who was stationed in a combat zone is considered a combat veteran. And seeing boys mangled every day is certainly criteria for her getting PTSD, just like our nurses and EMTs on the home front get PTSD along with burnout.. One does not have to be 'shot at' to get PTSD. Even therapists who work with PTSD patients get secondary PTSD just from listening to the horrors. You are a liar.
Worst case I ever saw was a soldier who never saw combat. He was in incountry mortuary services. He worked in the morque.
