Consider the fact that, since Vietnam, we have fought total-war opponents with “enlightened” ROE. I could see a connection with sending soldiers to places as targets while hamstringing their ability to defend themselves might make for a real PTS disorder.
MrT5 was there, and several other places in his 30 years of service. He was right, I think in saying that if the govermnment wanted enemies to brought to heel alive, they should send in diplomats/UN, but not soldiers. Soldiers are trained to make enemies dead and win wars-to expect them to do otherwise is an unfair burden, and certain to cause damage.
