> Is the incidence of "fragging" in Vietnam something that is genuinely well-documented
No idea. However, growing up with Vietnam vets, you get the impression that it was a real concern for officers smart enough to recognize it and bad enough to deserve it.
Viet Nam *was* a bad war that did bad things to people. For many soldiers and Marines. it was virtually nonstop combat for a year or more... that'll mess with ya. And then you dump a Lt. on 'em who doesn't know which end the bullets come out, and has too much ego to ask the Sarge's advice when nobody else is listening... it's a recipe for disaster.
