As I remember, during the draft you were sent where they needed you, which is why so many people enlisted trying to get someplace that they would rather be than where they may be sent if they had a low number.
Doing mandatory service has pros and cons. Maybe more cons now because of the way that things are going on the PC aspect of things. At one time, it was a good thing, people became more self sufficient, responsible and patriotic. They had sacrificed and appreciated things more.
I don’t know if a draft would have the same outcome now. A lot has changed and not necessarily for the better.
My (much) older brother, whose draftability would have been in the 1950s-60s, told me when discussing military service that it was one life experience he really missed having. He was “4F” due to a pin in his arm. All his friends had been drafted, and what he saw made him appreciate the discipline and skills, and that special camaraderie, they had gained in the service.
Whether any of that could ever be reconstructed is quite another story.
