The Air National Guard's federal mission is to maintain well-trained, well-equipped units available for prompt mobilization during war and provide assistance during national emergencies (such as natural disasters or civil disturbances). During peacetime, the combat-ready units and support units are assigned to most Air Force major commands to carry out missions compatible with training, mobilization readiness, humanitarian and contingency operations such as Operation Enduring Freedom in Afghanistan.
The Department of the Air Force is headquartered in the Pentagon, Washington D.C. The service is organized in nine major commands throughout the world which provide combat aircraft, airlift, refueling, reconnaissance and other support to the Unified Combatant Commands.
The Air Force also has more than three dozen field operating agencies and direct reporting units which directly support the mission by providing unique services.
Together with Air Force Reserve and Air National Guard forces, the United States Air Force is the best in the world.
