What does AOR stand for in the context of a Combatant Command?

• A. Allied Operations Region
• B. Area of Responsibility
• C. Agency Operational Realm
• D. Administrative Operational Range

Answer: (B)

The key idea is the geographic scope assigned to a Combatant Command. An Area of Responsibility is the geographic region that a CCMD is charged with planning, directing, and executing military operations within. This framework ensures unity of command across services and with allies in that region, guiding force posture, contingency planning, and crisis response. The other terms aren’t standard designations for a CCMD’s scope and don’t capture the formal geographic responsibility defined for command and control. Note that Area of Operations is a related concept used to describe where ongoing operations are conducted, which can fall within the broader Area of Responsibility, but the official CCMD term for the command’s geographic remit is Area of Responsibility.
