In addition to nationwide flying units, Fourth Air Force commands numerous support units representing a broad spectrum of Air Force specialties such as aircraft maintenance, logistics, and aerial port. They oversee, regional medical headquarters that train to deploy with medical center personnel to establish contingency hospitals. Other units specialize in security forces, civil engineering, aeromedical evacuation, medical services and patient staging, communications, combat camera, airlift control, and basic military training. 

During Operations DESERT SHIELD and DESERT STORM (1990-1992), more than 8,000 personnel were mobilized, and hundreds of others voluntarily augmented active-duty forces in the United States, Europe and Persian Gulf. This number included more than 2,800 medical personnel assigned to Fourth Air Force units. 

More than 1,000 personnel from Fourth Air Force units were called to active duty to support the crisis in Kosovo in the late 1990s. Hundreds more supported Operation ALLIED FORCE (1999) in volunteer status. 

Approximately 4,000 Fourth Air Force personnel were mobilized after September 11, 2001, in the support of global contingency operations and more than 20 percent of these numbered air forces personnel have served or continue to serve in Operations ENDURING FREEDOM, IRAQI FREEDOM and NOBLE EAGLE. 

Fourth Air Force units also provided aid and assistance for several natural disasters, including the catastrophic Midwest floods and California wildfires in 1993; the Northridge (Los Angeles) earthquake in 1994; the bombing of the Oklahoma City Federal Building in 1995; Hurricane Katrina; and the Central Asia Tsunami in 2005. Most recently, assigned unit members provided support to civil authorities in fighting California wildfires. 

Assigned units routinely support United Nations and Department of State missions. Fourth Air Force personnel were on the first teams into Haiti for Operation UPHOLD DEMOCRACY (1994-1995), and among the first Vigilant Warrior deployments to Southwest Asia during the first Persian Gulf War. In Operations ENDURING FREEDOM and IRAQI FREEDOM, 4th AF personnel have continually supported, with mobilization and volunteerism, global contingency operations and other humanitarian missions on a daily basis since September 11, 2001.
