I have not served in the U.S. armed forces. There was a draft back in my younger days. The prevailing thought amongst young adults was to wait until called. That is, of course, unless you had a low draft number, like 3 or 6. Since you knew you were going to be called, you signed up just to get rid of the hassle.
My father served for a while. He was discharged after training due to a back injury. Everyone else in his unit was killed during a Pacific beach landing in World War Two.
