Im surprised you know bout that , as young as you are.....
Im a history buff, grew up with a history addicted father(dad missed the Vietnam draft by 28 days, he got his draft card and 28 days before his report date, Congress pulled the plug) and a grandfather(served in WW2(German Luftwaffe and Korea(with the 75th RTI) Both of whom collected war memorabilia and such. I have a minor in American History and a second minor in World History. Granted, those minors are worthless pieces of paper and I often clashed with instructors during those courses for simply regurgitating text books.
My wife refuses to go to any more museums or watch any movie or show that has a historical reference. I have a tendency to point out inaccuracies.
But honestly, my biggest connection to the Vietnam was was my very first Plattoon Sergeant. He had served in the Marines infantry during the war, had a pair of Purple Hearts from it. After the war, he got out for a few years before rejoining the National Guard.
Anyway, we were at Fort Dix for training for my first Annual Training. Doing a field training exercise and our mission was to defend and secure the FOB(basically a camp). So I was out in observation post, at night, in late June. He was with me. Night was clear as clear can get. We were set up with a clear shot of the horizon across the field. Anyway, we’re just talking real low, when all of a sudden, he jerked ridge as board. Grabbed a pair of binoculars, it was about 2 am so I thought he was nuts. He goes: “call it in, OPFOR(our training pretend bad guys) sited at 1000 meters.” I paused, I didn’t see crap. He said call it in, I seriously thought the dude was nuts. Then he grabbed me by the shoulder. Pointed in the direction he was looking. Told me to look at this one particular star on the horizon between the trees. So I did for a moment or two. And sure enough, every few seconds, the star would disappear. Revealing a faint human silhouette.
We lit them up. Destroyed that attack. He told me afterwards, that’s how one stayed alive in Vietnam.
He retired a few months and passed away a year or so later. Lung cancer.
Kind of sinking in now that I think about, I’m probably one of the few remaining currently serving soldiers that served with any Vietnam vets.
SpaceX be lucky if their cameras on the launch site can see the launch
