Corpsman

History

Following the war, the hospital corps changed its rating title to the generic term it had used all along—hospital corpsman. The rates of hospital corpsman third class (HM3), second class (HM2), and first class (HM1), and chief hospital corpsman (HMC) were supplemented by senior chief hospital corpsman (HMCS) and master chief hospital corpsman (HMCM) in 1958.
