the 454th Group led its wing through determined opposition. The squadron also flew air support and air interdiction missions against marshalling yards, troop concentrations and rail lines for Operation Strangle, the effort to cut German supply lines in Italy north of Rome between March and May 1944. The squadron participated in the drive to Rome; Operation Dragoon, the invasion of southern France; and Operation Grapeshot, the Spring 1945 offensive in Northern Italy. The squadron left Italy in July 1945 and reformed at Sioux Falls Army Air Field, South Dakota the following month. It was redesignated as a very heavy bombardment squadron in anticipation of training and redeployment to the Pacific, but with the Japanese surrender, it was inactivated in October. Air Force reserve The squadron was reactivated in April 1947 at McChord Field, Washington as a reserve unit. It trained under the supervision of Air Defense Command's 406th AAF Base Unit (later 2345th Air Force Reserve Training Center). The squadron was nominally a heavy bomber unit, but it is not clear whether it had any combat aircraft assigned. In 1948 Continental Air Command (ConAC) assumed responsibility for managing reserve and Air National Guard units from ADC. The May 1949 Air Force Reserve program called for a new type of unit, the Corollary unit, which was a reserve unit integrated with an active duty unit. The plan was viewed as the best method to train reservists by mixing them with an existing regular unit to perform duties alongside the regular unit. The squadron moved to Spokane Air Force Base, Washington, where it operated the Boeing B-29 Superfortresses of the regular 92d Bombardment Wing located there. All reserve corollary units were mobilized for the Korean War. As the 92d Wing was beginning to convert to the Convair B-36 Peacemaker, the squadron was called to active duty, its personnel were used as fillers for other organizations, and it was inactivated on 16 June 1951. The reserve mobilization for the Korean War had left the reserve without aircraft, and the reserves did not receive aircraft again until July 1952. In preparing for the receipt of aircraft, in June 1952, ConAC activated the 454th Troop Carrier Wing at Portland International Airport, Oregon to replace the 922d Reserve Training Wing, the non-flying headquarters for reserve units there. The squadron was redesignated the 736th Troop Carrier Squadron and activated with the 454th Wing. It began training with
