1st Battalion, 327 Infantry (Airmobile Infantry) with SVC Ribbon Pin

two battalions of 327th Infantry deployed to Vietnam in 1965, where they were joined by the rest of the division in late 1967. The 2nd Battalion, 327th Infantry, was the last unit of the 101st Airborne to leave Vietnam, departing in April 1972, making it the longest serving unit in combat during the Vietnam War. While still at Fort Campbell, Kentucky, the remaining elements of the 101st were severely stripped of personnel to support the war effort. When ordered to deploy, it was necessary to fill empty manning slots with non-airborne-qualified soldiers, effectively making these units of the division airborne in name only.
