Could I just add to that?
One of my tours was a year long. I was a military observer in Sarajevo during the war. To be honest with you, if you're on any tour of more than six months, as the doctor said, you're going to start having symptoms. I actually started having symptoms of PTSD, but I didn't realize it, nine months into my tour. So I was already ill and was still in theatre. So it just compounds the injury, I think, by lengthening the tours.
