Ho Chi Minh trail
By the end of 1965, the 20th TASS was assigned the mission of directing interdiction of the Ho Chi Minh trail; this was dubbed Operation Tiger Hound. The squadron's original forward operating bases were at Khe Sanh, Kham Duc, and Kon Tum, which were very close to the Ho Chi Minh Trail, unlike Da Nang, which was the width of the country away. Other forward sites were added later for additional missions assigned to the squadron – Đông Hà, Quảng Trị City (La Vang Airfield), Huế Citadel Airfield, Huế/Phú Bài, Tam Kỳ, Quảng Ngãi, Đắk Tô, Pleiku, and Quảng Trị Combat Base.
