The
United States Army (
USA) is the largest branch of the
United States Armed Forces and performs
land-based military operations. It is one of the seven
uniformed services of the United States, and is designated as the
Army of the United States in the United States Constitution, Article 2, Section 2, Clause 1 and United States Code, Title 10, Subtitle B, Chapter 301, Section 3001. As the largest and senior branch of the U.S. military, the modern U.S. Army has its roots in the
Continental Army, which was formed (14 June 1775) to fight the
American Revolutionary War (1775–83)—before the U.S. was established as a country. After the Revolutionary War, the
Congress of the Confederation created the United States Army on 3 June 1784, to replace the disbanded Continental Army. The United States Army considers itself descended from the Continental Army, and dates its institutional inception from the origin of that armed force in 1775.
