Which chain runs from the president, to the secretary of defense to operating forces?

• A. The Administrative chain
• B. The Unified chain
• C. The Naval chain
• D. The Operational chain

Answer: (D)

The main idea here is understanding two parallel lines of authority: one handles administration, management, and support within the services, while the other directs actual military actions. The chain that runs from the President through the Secretary of Defense down to the operating forces is the operational chain of command. It is the line of authority for directing combatant commands and the forces that carry out missions, giving the president and DoD the power to task and control those forces in real operations. The administrative chain, by contrast, covers service-wide supervision, personnel, logistics, and budgets rather than battlefield orders. A naval-specific chain would limit direction to the Navy’s own units, and a unified chain isn’t the term used for the authority that directs ongoing operations across all services. So directing actions to the forces in the field comes from the operational chain.
