Which of the following best describes the scope of Combatant Commands (CCMDs)?

• A. They operate only in coalition with allied nations.
• B. They operate within assigned geographic areas or functional responsibilities.
• C. They only conduct humanitarian missions.
• D. They are limited to air operations.

Answer: (B)

Combatant Commands are organized around a defined scope: either a geographic area of responsibility or a functional area. That means a CCMD is responsible for planning and executing military operations within a specific region or for a particular mission domain that crosses geography. They oversee all aspects of operations within that scope—air, land, sea, cyber, and space as needed—rather than being limited to one type of mission or to operating only with allies. So the best way to describe their scope is that they operate within assigned geographic areas or functional responsibilities.
