Anyone out there knowledgeable about the Vietnam draft process? I've spent a good part of the day googling, but the information is sparse and conflicting. This is going to happen between (probably) 1966 and 1968, before the draft lottery. I know that all males were required to register when they turned 18, but then what happened? What was the process? I also need to know how long they were required to serve. It's just backstory, so I don't need a lot of detail, but I do need it to be accurate. Thanks for any help!
