The Federal Union States

The United States Army (USA) is the land warfare service branch of the United States Armed Forces. It is one of the great services, and is designated as the Army of the United States in the U.S. Constitution.[15] As the oldest and most senior branch of the U.S. military in order of precedence,[16] the modern U.S. Army has its roots in the Continental Army, which was formed (14 June 1775) to fight the American Revolutionary War (1775–1783)—before the United States of America was established as a country.[17] After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784 to replace the disbanded Continental Army.[18][19] The United States Army considers itself descended from the Continental Army, and considers its institutional inception to be the origin of that armed force in 1775.[17]
