The draft was a method of choosing people for military service.<quoted text>
""Many did volunteer for the draft," said Kondratiuk. "The minimum enlistment was three years in the Army. If you volunteered for the draft, you'd only get two years."
You were considered for the draft when you filled out your elective service card. There was no volunteering.
If you got drafted you served two years, if you enlisted it was longer.
