I was in medical school with a deferment when the lottery was held. I was due to graduate in 1972 so I was considering the Berry Plan. The Associate Dean was a General in the Air Force Reserves and told me that the draft would end for sure in 1972, and not to sign up for the plan. I did not sign up, and of course the draft did end in 1972. I was fortunate.
[Ed. note: Physicians were subject to a separate military draft requiring two years’ service. The Berry Plan allowed physicians several possible options, including deferment of military service after internship, until completing one year of residency. The regular draft and the "doctors’ draft" ended in early 1973].
