The 82nd Airborne Division is an airborne infantry division of the United States Army, specializing in parachute assault operations into denied areas with a U.S. Department of Defense requirement to "respond to crisis contingencies anywhere in the world within 18 hours." The All American division was constituted, originally as the 82nd Division, in the National Army on 5 August 1917, shortly after the American entry into World War I. It was organized on 25 August 1917, at Camp Gordon, Georgia and later served with distinction on the Western Front in the final months of World War I. Since its initial members came from all 48 states, the division acquired the nickname All-American, which is the basis for its famed "AA" shoulder patch. The division later served in World War II where, in August 1942, it was reconstituted as the first airborne division of the U.S. Army and fought in numerous campaigns during the war.
