Not long after activation, ACC underwent organizational and mission changes. The first such major change was the transfer of the combat search and rescue (CSAR) mission from Air Mobility Command to ACC. With the realigning of search and rescue units, ACC gained additional resources, as well as a new mission. The formal transfer took place on 1 February 1993, when the Air Rescue Service (ARS) was assigned to ACC. On 2 July of the same year, the ARS was disestablished and rescue units became fully integrated in the same manner as other ACC units reporting to numbered air forces. The USAF Combat Rescue School was subsequently assigned to the 57th Wing at Nellis AFB, Nevada.
