The Ohio Air National Guard (OH ANG) is the air force militia of the State of Ohio, United States of America. It is, along with the Ohio Army National Guard, an element of the Ohio National Guard. As state militia units, the units in the Ohio Air National Guard are not in the normal United States Air Force chain of command. They are under the jurisdiction of the Governor of Ohio through the office of the Ohio Adjutant General unless they are federalized by order of the President of the United States. The Ohio Air National Guard is headquartered at Beightler Armory, Columbus, and its commander is Major General Mark E. Bartman. Under the "Total Force" concept, Ohio Air National Guard units are considered to be Air Reserve Components (ARC) of the United States Air Force (USAF). Ohio ANG units are trained and equipped by the Air Force and are operationally gained by a Major Command of the USAF if federalized. In addition, the Ohio Air National Guard forces are assigned to Air Expeditionary Forces and are subject to deployment tasking orders along with their active duty and Air Force Reserve counterparts in their assigned cycle deployment window.
