U.S. Army Law and Legal Definition
The U.S. Army is the subdivision of the U.S. armed forces answerable for land-based military operations. It is one of seven U.S. uniformed services and it is the largest and oldest established branch of the U.S. military. The U.S. Army has its ancestors in the continental army which was organized to meet the demands of the American Revolutionary War. Later, after the end of the revolutionary war, Congress created the U.S. Army to replace the disbanded continental army.
The head of the U.S. Army is the Secretary of the Army, who is appointed by the U.S. President with the advice and consent of the senate. The U.S. Army’s mission is to fight and win the nation’s wars by providing prompt, sustained land dominance across the full range of military operations and spectrum of conflict in support of combatant commanders. In general, the U.S. Army can be classified into the active component and the reserve component. The reserve component can again be classified into U.S. Army Reserve and the Army National Guard. Likewise, on the basis of the mission that the U.S. Army fulfills, it can be classified into operational army and institutional army. The operational army includes numbered armies, corps, divisions, brigades, and battalions that conduct full spectrum operations around the world. While the institutional army assists the operational army. Hence, the U.S. Army includes land combat and service forces and such aviation and water transport.
