What runs from the U.S. President to the Combatant Commanders?

The chain of command is a critical framework that delineates the flow of authority and responsibility in military operations. It establishes a clear line from the President of the United States, as the Commander-in-Chief, directly to the Combatant Commanders, who are responsible for carrying out military operations in their respective areas of responsibility.

This structure ensures that commands are consistent and that strategic decisions made by the President are executed effectively throughout the military. The chain of command is essential for maintaining discipline, ensuring efficient communication, and facilitating the commander's intent in military operations. This hierarchical relationship is vital for responding promptly to national security needs and conducting operations effectively.

The other options, while they hold significant roles within the defense structure, do not represent the direct line from the President to the Combatant Commanders. The Secretary of Defense acts as a key intermediary, while bodies like the Armed Forces Policy Council and the Under Secretaries of Defense have specific advisory and administrative functions that do not constitute a direct command flow.
