"Protection of friendly forces and territories from air attack by hostile aircraft is the primary mission of U.S. air defense forces. Interoperability among the Military Departments is needed in an air defense scenario to eliminate fratricide and to provide for effective use of equipment. Reinforcement units are those forces designated to be transferred to the supported commander during the execution of an operation. The Republic of Korea/ U.S. Air Component Command (ACC) is responsible for air defense on the Korean peninsula. The 2nd Infantry Division, 8th United States Army, Korea, used the Forward Area Alerting Radar (FAAR) in Korea as an integral (organic) early warning radar. The Division was required to retire its radar system by the end of fiscal year 1990 as part of a Defense Management Report Decision. The audit assessed the effects of interoperability issues on air defense capabilities in the Pacific theater. In addition, it assessed the ability of reinforcement units in the Pacific and the ability of the ACC in Korea to perform their missions."
