Which sequence correctly lists the levels in the operational chain of command?

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

Answer: (A)

In military operations, authority flows from political leaders to the field in a stepwise chain. The National Command Authority, made up of the President and the Secretary of Defense, authorizes action and then delegates command through the levels of the armed forces. The next level is the Combatant Commanders, who oversee large geographic or functional commands. Within each of these, Component Commanders lead their service-specific components. For naval forces, those components are organized under a Numbered Fleet. Operational planning then breaks down into smaller units: Task Forces, which split into Task Groups, then Task Units, and finally Task Elements that carry out the actual tasks. So the full sequence is National Command Authority → Combatant Commanders → Component Commanders → Numbered Fleet → Task Force → Task Group → Task Unit → Task Element. This ordering reflects how orders become progressively more detailed and specialized as they move down the chain. The other options omit levels, misorder the chain, or restate only political leadership, which doesn’t capture the full operational hierarchy.
