How many unified combatant commands exist in the Department of Defense, and how are they categorized?

• A. 11 unified commands — four functional and seven geographic
• B. 9 unified commands — five functional and four geographic
• C. 12 unified commands — six functional and six geographic
• D. 8 unified commands — four functional and four geographic

Answer: (A)

Unified combatant commands are arranged to execute joint, cross-service operations under a single commander. There are 11 of them: four functional commands that handle global mission areas crossing regional boundaries, and seven geographic commands that oversee operations in defined regions around the world. The functional group covers global capabilities such as special operations, strategic deterrence and global strike, global mobility, and cyberspace operations. The geographic group provides region-specific command and control for areas like Africa, Europe, the Indo-Pacific, North America, and South America, ensuring tailored security cooperation and theater operations. This combination—11 total with four functional and seven geographic—explains why the correct choice lists that split.
