Earlier, I was mentioning that peacekeeping missions caused as much PTSD as many combat missions. That is what I was referring to. In many cases, to watch helplessly while atrocities are being committed can be just as traumatic as going to the front and being involved in military combat.
The nature of the trauma typically varies from one war to another. There is no doubt about that. The types of trauma vary, but the main symptoms remain essentially the same.
