Dont get me wrong I tend to agree that war will cause it far more often. It's just that the statement you made was an absolute one. Consider also that there are cases where women who are brutally raped have it. Combat isnt the only way to trigger it.
Ehh I'm damn sure there has been PTSD from tyrannical governments. Watching secret police execute your husband while your holding a screaming 3 year old child. Damn near certainly would do it among many other messed up things they do.
