transport of personnel, supplies and equipment. The 197th Air Transport Squadron (later Military Airlift Squadron) flew missions to the Caribbean, Europe, Japan, South Vietnam, Thailand and Australia. During the height of the Vietnam War, the squadron routinely flew trans-Pacific medical evacuation missions from hospitals in South Vietnam, Japan, and the Philippines of wounded servicemen and women to the United States, being designated as an Aeromedical Transport Squadron. In 1969 the Military Airlift Squadron designation was returned and the unit again flew scheduled transport missions for Military Airlift Command (MAC). Air Refueling In 1972, military requirements resulted in a change in mission when the group was reassigned from MAC transport duties to the Strategic Air Command (SAC). Under SAC the group became an Air Refueling unit, being with the air refueling version of the C-97 transport, the KC-97 Stratofreighter. Familiarity with the aircraft led to a smooth transition from MAC to the new refueling mission. In 1977, SAC announced that Air National Guard refueling units would begin to upgrade to the Boeing KC-135 Stratotanker. The 197th Air Refueling Squadron has been flying the KC-135 for almost 40 years. During the 1991 Gulf War, Air National Guard tanker units were quickly called into action. An around-the-clock airlift began to support the buildup to the conflict, Operation Desert Shield. Tankers and crews from the 161st were some of the first to arrive in Saudi Arabia. Elements of the 197th ARS were assigned to the 1709th Air Refueling Wing (Provisional), flying from King Abdul Aziz Air Base, Jeddah, Saudi Arabia. From the start and for the duration, tankers servicing the conflict left Phoenix weekly, loaded with maintenance and support technicians who worked in the Saudi Arabian desert up to 45 days, and in some cases more. As the allies prepared to move against Iraq, aircraft crews, maintenance personnel, medics, fire fighters, security forces and food service technicians were dispatched to bases in Europe and the United States. Before the war in the Persian Gulf was concluded more than two-thirds of the force assigned to the 161st Air Refueling Group had served on active duty in some capacity to support the Middle East effort. In 1994, 1995 and 1997 the unit deployed to Pisa, Italy where our tankers supported NATO operations in Bosnia. 1997 also saw the 161st facing challenges in the United Arab Emirates. The unit was vital to the success of Operation Deny
