I have a friend who was a "black" sniper in VN. He is 100% disabled for both mental and physical reasons, not the least of which is PTSD of the worst sort. He now has one of the finest model railroads in this part of the country and enjoys is immensely -- but even with medicine the nightmares and insomnia still come. I only hope that the guys and gals who are "over there" have proper care before and after they leave the service.
