The squadron served for two and a half years combat duty during the Vietnam War, primarily flying missions over the Ho Chi Minh Trail in Laos.

[1] In March 1944 the 348th was disbanded when the AAF found that standard military units, based on relatively inflexible tables of organization were proving less well adapted to the training mission.

[1] The 329th Transport Squadron delivered cargo and mail throughout the Mediterranean Theater of Operations from its activation in March 1944 until it was inactivated in September 1945.

[3][4] The night interdiction tasks of the 609th were gradually taken over by squadrons flying Lockheed AC-130 gunships, and the A-26 aircraft were phased out of active service by November 1969.

[4] By the time the last four surviving A-26s were withdrawn at the unit stand down, the squadron had flown 7,159 combat missions, and been credited with destroying 4,268 enemy supply trucks.

[4] The remains of two squadron pilots, Maj. James E. Sizemore and Maj. Howard V. Andre, shot down over Laos in 1969, were recovered in 2013 and buried at Arlington National Cemetery[6] This article incorporates public domain material from the Air Force Historical Research Agency
