These support units include a headquarters squadron, medical, personnel, finance and other units as needed.
As of 2012, there are currently seven wings designated specifically as "Bomb Wings" in the United States Air Force. Six of these wings are active-duty units, while one wing is an Air National Guard unit. These units fall under the control of the Strategic Air Command Major Command (MAJCOM).
The acronym "AOR" stands for a military Area of Responsibility. An AOR is used mostly in a wartime context. It refers to the division of geographic regions in a location. Each region has a specific combatant commander assigned to command and direct operations in that location. The commander is responsible for air, ground and sea missions and support operations, as well as personnel assigned to that particular command. Combatant commanders have authority over all military personnel under their command, regardless of branch of service. Areas of Responsibility are established by the President of the United States. This information is contained in the U.S. Unified Command Plan (UCP). The latest version of the UCP was published on December 17, 2008. It names each command's AOR and establishes boundaries of each.
