Tiger Force was a long-range reconnaissance patrol unit of the United States Army's 101st Airborne Division which served in the Vietnam War. Organizationally part of the 327th Infantry Regiment's 1st Battalion (Airborne) in the 101st Airborne Division's 1st Brigade (Separate), the unit was founded by Major David Hackworth and primarily active from November 1965 to November 1967. It gained notoriety after investigations during the course of the war and decades afterwards revealed the unit had committed extensive war crimes against hundreds of Vietnamese civilians. Hackworth, who left Vietnam before the unit began committing war crimes, claimed he was unaware of Tiger Force's atrocities and refused to speculate on why they occurred.
