What component resulted from the 1947 reforms to unify command structures across services?

• A. The Joint Chiefs of Staff
• B. The Department of Defense
• C. Unified combatant commands
• D. The Central Intelligence Agency

Answer: (C)

The central idea is unity of command across the armed services. The 1947 reforms established unified combatant commands—regional or functional commands that draw forces from more than one service and are led by a single commander. This structure fixes the problem of services operating in silos by giving one commander authority to plan and execute operations with mixed forces, under the Secretary of Defense. The Joint Chiefs of Staff, by contrast, serves as an advisory body, not a unified command; the Department of Defense is the overarching civilian-military organization that houses the services, and the CIA is an intelligence agency created by the same act. Unified combatant commands embody the move toward joint operation and coordinated command across services.
