Department of the Army
The mission of the Department of the Army is to organize, train, and equip active duty and reserve forces for the preservation of peace, security, and the defense of our Nation. As part of our national military team, the Army focuses on land operations; its soldiers must be trained with modern arms and equipment and be ready to respond quickly.
The Army also administers programs aimed at protecting the environment, improving waterway navigation, flood and beach erosion control, and water resource development. It provides military assistance to Federal, State, and local government agencies, including natural disaster relief assistance.
The American Continental Army, now called the United States Army, was established by the Continental Congress on June 14, 1775, more than a year before the Declaration of Independence. The Department of War was established as an executive department at the seat of government by act approved August 7, 1789 (1 Stat. 49). The Secretary of War was established as its head. The National Security Act of 1947 (50 U.S.C. 401) created the National Military Establishment, and the Department of War was designated the Department of the Army. The title of its Secretary became Secretary of the Army (5 U.S.C. 171). The National Security Act Amendments of 1949 (63 Stat. 578) provided that the Department of the Army be a military department within the Department of Defense.
