Great story. There was a lot of "Nutting" going on in Vietnam but most of it was done to the GIs by the NVA & VC. I read a book by a former Vietnam nurse I believe it was called "Inside the Death Factory". One of the incidents she described was when a whole squad of 10 GIs were captured and tied upside down by the VC and castrated. All had severed cock & balls shoved into their mouths, maybe not their own. The few that survived were taken to her to be treated. It was interesting to read about a VC getting the same treatment.
