The United States Army is the land warfare service branch of the United States Department of Defense. It is one of the eight U.S. uniformed services, and it is tasked with the defense of the nation, including land operations, humanitarian missions, and disaster relief both domestically and internationally.
History
- Establishment: The Army traces its origins back to the Continental Army, established on June 14, 1775, by the Second Continental Congress to coordinate the military efforts of the thirteen colonies in their struggle against British rule during the American Revolutionary War.
- Post-Revolutionary War: After the Revolutionary War, the Army was downsized but remained active. The United States Constitution vested Congress with the authority to raise and support armies, which led to the formal establishment of the United States Army by the Congress of the United States in 1784.
- Civil War: The Army played a pivotal role in the American Civil War, where it was split into the Union Army and the Confederate Army, marking one of the largest military engagements in U.S. history.
- 20th Century: The Army saw extensive involvement in major conflicts such as World War I, World War II, the Korean War, and the Vietnam War. These wars expanded the Army's size, capabilities, and international presence.
- Modern Era: Post-Cold War, the Army has been involved in peacekeeping operations, counter-terrorism efforts, and nation-building missions, including operations in Iraq, Afghanistan, and various African nations.
