The American People's Army (APA) is the main branch of the American Armed Forces responsible for land-based military operations. It is the largest and oldest established branch of the American military. The modern army has its roots in the Continental Army which was formed on 14 June 1775, to meet the demands of the American Revolutionary War before the establishment of the United States. The Congress of the Confederation officially created the United States Army on 3 June 1784 after the end of the Revolutionary War to replace the disbanded Continental Army. Many U.S. Army units and personnel joined with the communist militias of the Rebel Faction during the Second American Civil War, and after the war, the new American People's Army took over most of the U.S. Army's remaining assets.
