I remember one night during TET in 1968. I was on guard duty near the back gate at LONG BIHN. At about midnight, one of the guys lit up a joint and I didn't want the odor of the joint to alert the VC.
Well, I totally lost it. I knocked him down, took my M-14, locked and loaded, and stuck the barrel in his mouth and had the other guard call the Sgt. of the Guard and ask that he come out ASAP.
When he arrived, I had cooled down a little bit. The Sgt. took that guard and replaced him on the spot.
Nothing ever happened to me because of it, but I don't know about the other guy. This happened sometime in January of 1968, but I don't remember the exact date.
Thank you for sharing your experience, Charles, and Welcome Home.
