In December 1972, the 8th became involved in Operation Linebacker II. Designed to make the enemy more serious about the peace negotiations in progress at Paris, France, the 8th TFW launched 524 sorties for bombing missions against North Vietnam between 18 and 31 December 1972. Early in 1973, the Wolf Pack mission included air interdiction into Laos against communist insurgents in Cambodia. All combat operations ended on 15 August 1973. In mid-1974 action began to phase down at Ubon Airfield, Thailand, and the wing began to lose personnel, aircraft, and units. The last scheduled F-4 training flight occurred on 16 July 1974.
