Please don't get me wrong. I don't doubt that Marine draftees were every bit as good as the volunteers. I just didn't want to be one of them. :=)
A friend who had been drafted into the Army told me that his service number (which is used for everything in the military) distinguished him from a volunteer. I recall him telling me that his number started with the letters "US" (indicating a draftee) and volunteers' numbers started with "RA" (for 'regular Army'). I've never independently confirmed this but I believe it to be the case.

I was a volunteer and still remember my RA #. Yes, your assumption is correct. Bush/Cheney 2004
