The VN vet remark was not a poke at VN vets.
I have a father that did two tours in the ‘Nam with 3rd Marines at Dong Ha, the Rockpile, Con Thien, and others.
The point made was this. The vet was trained, experienced, ready, and had better weaponry than Officer Dinkheller. He used them to murder Dinkheller, even though Dinkheller was doing his job and had the advantage at first.
And yes, he was deranged.
Thanks.
