As state militia units, the units in the Illinois Air National Guard are not in the normal United States Air Force chain of command. They are under the jurisdiction of the Governor of Illinois though the office of the Illinois Adjutant General unless they are federalized by order of the President of the United States. The Illinois Air National Guard is headquartered at Camp Lincoln, Springfield, led by its Commander, Brigadier General Peter Nezamis; Chief of Staff, Brigadier General William Robertson; and Command Chief Master Sergeant Jimmie E. Flinn.
