Prior to 1966 my draft board was constantly re-classifying me I-A even with good grades and school certifications of attendance. So being from a military family anyway, I joined senior Army ROTC at the University of Georgia and thus eliminated the draft board’s jurisdiction.
Joining senior ROTC was essentially enlisting in the Army. I received a reserve Army commission as a 2nd Lieutenant. The Army allowed me to finish the requirements for my pharmacy license and I entered service in October 1970 as a Captain. I was assigned to Walter Reed Army Medical Center and ended up serving 20 years rising to the rank of Lieutenant Colonel.
So the threat of the draft ended up setting me off on a military career. After retirement in 1990, I have been an Associate Professor at the Medical College of Georgia now having 23 years of service at Georgia Regents University.
