The HM/HMDA Ratings
The Surgeon's Steward rating was established in 1838, and in 1866 the rating name changed to Apothecary. In 1898, the Apothecary rating had its name changed to Hospital Steward, and in 1917 to Pharmacist's Mate. Finally, in 1948, the Pharmacist's Mate rating was changed to today's, familiar, Hospital Corpsman.
The Dental Technician rating was first developed in 1948, but, in 2005, the rating was folded into the HM rating and is referred to as HMDA.
Hospital Corpsmen perform duties as assistants to medical and dental professionals in the prevention and treatment of disease and injury, and assist health care professionals in providing dental and medical care to Naval personnel and their families. They may function as clinical or specialty technicians, medical administrative personnel and health care providers at medical treatment facilities. They also serve as battlefield corpsmen with the Marine Corps, rendering emergency medical treatment to include initial treatment in a combat environment.
Qualified Hospital Corpsmen may be assigned the responsibility of independent duty aboard ships and submarines; Fleet Marine Force, Special Forces and Seabee units, and at isolated duty stations where no medical officer is available.
Hospital Corpsman class "A" school is approximately 19 weeks in duration, and the school is located in Fort Sam Houston, Texas. The HM rating requires a five-year enlistment obligation.
