The 502nd Infantry Regiment (502nd INF), previously titled the 502nd Parachute Infantry Regiment (502nd PIR), is an airborne infantry regiment of the United States Army. The regiment was established shortly after the American entry into World War II, and was assigned as a regiment of the 101st Airborne Division, "The Screaming Eagles", one of the most decorated formations of the U.S. Army. The regiment saw substantial action in the European Theater of World War II and was deactivated in 1945, shortly after the end of the war. Reactivating in a new form in 1956, the 502nd Infantry has served in the Vietnam War, the first Gulf War, Operation Iraqi Freedom, and Operation Enduring Freedom in Afghanistan. It was removed from parachute status with the rest of the 101st Airborne Division in 1969,
