I've been reading a multi-book Vietnam history, very interesting. It has lots of personal details about the whole 20th century history of the country. Being of draft age but in college, and with a high draft #, I didn't get called. I had friends and classmates who did get called, and some are no-longer with us. I also have a friend who's a bit older than me, he's a professional engineer, and was a member of the Vietnamese armed forces, he patrolled the waters, and when the end came, he was able to get his family out and came to the USA. He doesn't talk about it at-all, but he has spoken to me when I asked him direct questions, after getting his cooperation. One thing he said is, "I didn't expect to live to be age thirty, given how the war was going."
Old men start them, young men fight them. Rest in peace, those who didn't return alive. Those who did make it back, I hope you have been able to become civilians, and to lead productive lives after your time in-country. It still angers me when I think of comments made disparaging Senator John McCain and his prisoner-of-war status.
