 Hospital corpsmen, or HMs, have been saving lives and helping sailors stay healthy for over 200 years. In that time, they've grown to the largest rating in the Navy with over 23,000 sailors. Affectionately referred to as DOC, these sailors have served in the medical field since the 17th century. However, the rate hospital corpsman was not established until 1898. Before that, they were known by various titles, such as Surgeons Mate, Apothecary, Surgeon Steward, Lob Lollie Boy, and Bayman. HMs also provide nutrition program support and are there to assist sailors trying to quit tobacco products. HMs can be found serving around the world in unique billets, ranging from SEAL teams, the Marines, to assisting victims in disasters and international exercises in foreign countries. Contact your nearest hospital corpsman to find out more information and how they can help you stay healthy.
