United States Army The United States Army (USA) is the land warfare service branch of the United States Armed Forces. 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 oldest and most senior branch of the U.S. military in order of precedence,[9] 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.[10] After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784 to replace the disbanded Continental Army.[11][12] 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.[10]
American Expeditionary Forces The American Expeditionary Forces (AEF) was the expeditionary force of the United States Army during World War I. It was established on July 5, 1917, in France under the command of Gen. John J. Pershing. During the United States campaigns in World War I it fought, alongside French and British troops, against the German Empire. Some of the troops fought alongside Italian forces in that same year, against the Austro-Hungarian Army. It helped the French Army on the Western Front during the Aisne Offensive (at Château-Thierry and Belleau Wood) in June 1918, and fought its major actions in the Saint-Mihiel and Meuse-Argonne Offensives in late 1918.
