The Army Medical Department of the U.S. Army (AMEDD), formerly known as the Army Medical Service (AMS), encompasses the Army's six medical Special Branches (or "Corps"). It was established as the "Army Hospital" in July 1775 to coordinate the medical care required by the Continental Army during the Revolutionary War. The AMEDD is led by the surgeon general of the U.S. Army, a lieutenant general.
The AMEDD is the U.S. Army's healthcare organization (as opposed to an Army Command), and is present in the Active Army, the U.S. Army Reserve, and the Army National Guard components. It is headquartered at Fort Sam Houston, San Antonio, Texas, which hosts the AMEDD Center and School (AMEDDC&S). Large numbers of AMEDD senior leaders can also be found in the Washington D.C. area, divided between the Pentagon and Walter Reed National Military Medical Center (WRNMMC).
The U.S. Army Medical Center of Excellence, within the AMEDDC&S, provides training to the officers and enlisted service members of the AMEDD. As a result of BRAC 2005, enlisted medical training was transferred to the new Medical Education and Training Campus, consolidating the majority of military-enlisted medical training in Fort Sam Houston.
The current Surgeon General of the U.S. Army and commander of the U.S. Army Medical Command (MEDCOM) is LTG Mary Krueger (since 25 January 2024).
Both the AMEDD and the United States Army Medical Corps trace their origins back to July 27, 1775, when the Continental Congress established the "Army Hospital", which was at that time overseen by the "Director General and Chief Physician." Pennsylvania and the middle colonies picked up the task of caring for the incapacitated soldiers in various makeshift ways. Congress provided an Army medical organization only in times of war or emergency until 1818, at which point it created a permanent "Medical Department." The Army Nurse Corps originated in 1901, the Dental Corps began in 1911, the Veterinary Corps in 1916, the Medical Service Corps emerged in 1917 (during WW I the Sanitary Corps was created as a temporary organization to relieve U.S. Army physicians from a variety of duties), and the Army Medical Specialist Corps came into existence in 1947.
The Army Organization Act of 1950 renamed the Medical Department to "Army Medical Service" and on June 4, 1968 the Army Medical Service was renamed to the Army Medical Department.
A regimental coat of arms was devised for the Medical Department and was most likely first used in 1818. The twenty white stars on a blue background and the red and white stripes represent the U.S. flag of 1818. The green staff entwined with a green serpent combined two symbols: the rod of Asclepius from classical mythology symbolizing medicine and healing, along with the color green associated with the Medical Corps during the last half of the 19th Century. The colors Argent (silver/white) and Gules (red) are associated with the flag of the United States. The rooster is associated with the ancient Greek and Roman god of healing and medicine, Aesculapius. The ancient Greeks believed that the rooster's crowing at dawn drove away the evil disease-spreading demons from the temples so that it could be a place of healing. The torse (twisted rope) below the rooster shows alternating blue and silver colors which were representative of the Army in 1818. The Latin motto Experientia et Progressus (Experience and Progress) is meant to convey the steady and unfailing progress of the Army Medical Department since 1775.
The design of the AMEDD regimental insignia (crest) is derived from the regimental coat of arms. It is one of the US Army's fourteen regimental corps insignias. The insignias are worn over the right breast pocket on the Army Service Uniform (ASU) and signify a service member's branch of service. The "new" AMEDD insignia was approved on October 27, 2014.
In 1851, "a caduceus embroidered in yellow silk on a half chevron of emerald green silk" was first authorized and worn by hospital stewards of the Medical Department. The caduceus in its present form was approved in 1902. Today, the AMEDD branch corps insignia is a gold color medal caduceus, 1 inch in height. With the exception of the Medical Corps, each Corps is identified by a black enamel letter (or letters) centered on the caduceus indicative of the specific branch. The insignia for Medical Service Corps is silver.
The caduceus symbolizes the non-combatant role of the AMEDD and not medicine per se. It came into popular use for medicine in the United States after the First World War. As medical professionals returned to civilian practice, they brought the caduceus symbol back with them. Over time, Americans began to associate the caduceus with medicine. The Rod of Asclepius is the more appropriate symbol for medicine in a civilian setting.
There are currently six special officer branches (corps) in the AMEDD.
The Medical Corps consists of commissioned medical officers who are physicians (Doctors of Medicine and Doctors of Osteopathic Medicine) who have completed at least one year of post-graduate training (internship) or have been promoted from O-1 to O-3 following completion of medical school through USUHS or the HPSP. The MC traces its origins to 27 July 1775, when the Continental Congress created "a Hospital", essentially a Medical Department and corps of physicians, for the Continental Army. Medical officers in the United States Army were authorized uniforms only in 1816 and were accorded military rank only in 1847. Congress made the designation of "Medical Corps" official in 1908, although the term had long been in use informally among the AMEDD's regular physicians. Today, members of the MC work around the world at all echelons of the Army. The Chief of the MC is a major general, whereas the senior Army Medical Department officer is the Surgeon General (a lieutenant general).
Military physicians serve in one of several general career fields. The three main fields are operational field, clinical field, and research field.
Operational Medicine is the field of Army medicine that provides medical support to the soldier and his/her Chain of Command. Many operational physicians serve as Division, Brigade and Battalion level surgeons (the word "surgeon" is used to identify a physician that is assigned to a unit as a primary care provider and not necessarily as a General Surgeon). These physicians are either assigned through the "PROFIS" system or through permanent assignment (PCS). Deployments with units to combat theaters are for the duration of a deployment and the jobs are mostly filled by primary care physicians. A PROFIS provider can expect to be deployed away from their family for a total of 16 months (1 month before deployment, 12 months in theater, and 3 months for "stabilization" after return to the assigned units home station). This means that primary care physicians are deployed for longer periods than most "specialist physicians". A specialist (i.e. General Surgeon, Pulmonologist, Cardiologist, Trauma Surgeon, Rheumatologist) are usually deployed for 6 months. Operational Physicians should expect that more than 60% of their time will be spent in administrative roles and non-patient care. 40% of the operational providers time is spent caring for soldiers or supervising unit Physician Assistants (PA). With the recent Brigade Combat Team (BCT) restructuring, the demand for operational surgeons have increased. It is possible that the low retention rates of Captains and junior Major rank Physicians in the primary care fields are due to the discrepancies in deployment length and deployment frequency between primary care and specialty physicians.
Clinical Medicine is the field of Army medicine in which a physician in uniform performs similar functions to a physician in the civilian arena. These physicians are assigned to a PROFIS unit in one of the various Army MEDCEN (Medical Centers) and MEDDAC (Medical and Dental facilities). Primary care physicians usually deploy to fill battalion level surgeon positions. Medical specialists deploy to support CSH (combat support hospitals)
