Mine was somewhere in the 30's can't remember for sure. But they were drafting down into the low 200's that year. If you got drafted you went to basic, Fort Hood and then Saigon for assignment to the field with a bunch of pukes who did not want to be there with a bunch of lousy officers. So, not wanting to do that or flee to Canada, I enlisted in USMC for the shortest enlistment possible. Two years. It was horrid as first but by the end of my time there I was having a lot of fun. Do not regret it at all. My time in Viet Nam was on deck of USS Mobile or USS Denver. Never got SVN mud on my boots.👍
