The 101st Airborne Division is a United States Army modular light infantry division trained for air assault operations.
World War IIEdit
During the Vietnam War, the 101st Airborne Division fought in several major campaigns and battles including the fight for "Hamburger Hill" in May 1969. Upon its arrival in Vietnam in 1965, (1st brigade in '65 and 2nd and 3rd brigades in 1967), the division was an airborne unit. In 1968 it was re-designated first as an airmobile division, then in 1974 as an air assault division. Both of these titles reflect the fact that the division went from airplanes as the primary method of delivering troops into combat, to the use of helicopters as the way the division entered battle.
