Army of the United States

The Army of the United States was one of the four major service components of the United States Army. Today, the Army consists of the Regular Army, the Army National Guard of the United States, the Army National Guard while in the service of the United States, and the United States Army Reserve. Previously however the Army of the United States was a component. However, the Army of the United States has been inactive since the suspension of the draft in 1973 and the U.S. military's transition to an all-volunteer force. Personnel serving in the United States Army during a major national emergency or armed conflict (either voluntarily or involuntarily) were enlisted or inducted into the Army of the United States without specifying service in a component. It also includes the "Retired Reserve". Those are retired soldiers who have reached the required years of creditable service, or creditable service and age; regardless of the component, or components they formerly served in. The term "Army of the United States" or "Armies of the United States" is also the legal name of the collective land forces of the United States as prescribed by the United States Constitution. In this concept, the term "Army of the United States" has been in use since at least 1841 as in the title General Regulations for the Army of the United States. Also included by Act of the 39th Congress (1866) were the U.S. Volunteers, persons holding a brevetted rank, and the U.S. Veteran Reserve Corps.
