Who assigns the Area of Responsibility (AOR) for geographic combatant commands?

The assigning of the Area of Responsibility (AOR) for geographic combatant commands is a critical component of military organization and strategy. The President of the United States is responsible for defining and establishing the global framework within which military operations are conducted. This includes designating specific regions of responsibility to each geographic combatant command.

The President, as the Commander-in-Chief, has the authority to determine the strategic priorities and operational focus of the military. This decision is influenced by national security interests and geopolitical considerations. By assigning AORs, the President ensures that the military is organized effectively to respond to threats and fulfill strategic objectives on a global scale.

Other figures in the defense establishment, such as the Secretary of Defense or the Joint Chiefs of Staff, have key roles in military strategy and operations, but the ultimate authority for broad decisions such as AOR assignments lies with the President.
