Thank you General Patton for your night soil of a large male water buffalo opinion.
Whether it is called PTSD, combat fatigue, shell shock, or le cafard; it has been with us as long as there has been war. Although it did become more prevalent since WW1 with the 24/7 nature of modern war.
George Carlin was right, perhaps if we still called it "Shell Shock" instead of watering down the language and calling it PTSD, Vets would have gotten better help.
