The Army Medical Department of the U.S. Army, known as the AMEDD, comprises the six medical Special Branches of the Army. It is not a command of the U.S. Army but was established in June 1775 to coordinate the medical care required by the Continental Army. The AMEDD is led by The Surgeon General of the U.S. Army, a Lieutenant General. The AMEDD is found in all three components of the Army, including the Active Army, the U.S. Army Reserve, and the Army National Guard. Headquartered at Fort Sam Houston, San Antonio, Texas, which hosts the AMEDD Center and School, equal numbers of AMEDD senior leaders can be found in Washington D.C., divided between the Pentagon and Walter Reed Army Medical Center.

The current U.S. Army Surgeon General is Lieutenant General Eric Schoomaker.
