Unless things have changed since I was in the Army Medical Corp 30 some years ago, a doctor did not have to have a medical license to practice in the military or VA.
That changed in 1987. All AD and civil service military docs except those in a training program must have an active, valid license in one of the US states. I was on AD when it took place and there were a fair number of people who had to retake the USMLE in order to get a license.
Oh man, NOQ you are really scaring me....no license - from anywhere?
Given the lack of quality in the military 30 years ago, I wouldn’t doubt it. Still, that’s scary!
