Since 1974, the 101st Airborne Division has been the United States Army's "Air Assault" Division. The Division is capable of lifting, by helicopter, a 4,000-soldier combined arms force up to 150 kilometers behind enemy lines in one lift. Having approximately 281 helicopters, including three battalions of Apache attack helicopters, makes the "Screaming Eagles" the most versatile fighting unit in the Army.
