What is the sequence of the Operational Chain of Command?

• A. POTUS → SECDEF → Combatant Commanders → operational forces.
• B. POTUS → SECDEF → Service Secretaries → Service Chiefs → forces.
• C. The President and Secretary of Defense.
• D. NCA → Combatant Commander → Component Commander → Numbered Fleet → Task Force → Task Group → Task Unit → Task Element.

Answer: (A)

The main idea here is how authority for directing military operations flows from the top to the field units. The President, as Commander in Chief, holds the ultimate authority to direct use of forces. The Secretary of Defense acts as the senior adviser and implements the President’s directives, coordinating through the defense department. From there, Combatant Commanders—each responsible for a geographic or functional command—have the authority to direct the assigned forces in operations. Those forces are the actual units and personnel carrying out missions on the ground or at sea, in the air, or in cyberspace. This sequence—President → Secretary of Defense → Combatant Commanders → operational forces—captures how day-to-day operational direction is exercised. The other option that mentions only the President and Secretary of Defense omits the crucial step where Combatant Commanders hold and exercise operational control over forces. The other detailed option dives into a granular, internal chain that isn’t how the operational chain is formally defined, and it would blur the distinction between operational command and administrative/functional roles. So the best answer reflects the actual flow of operational authority from the top civilian leadership through the Defense Department to the commands that execute missions.
