Which branch of the chain of command is used to employ forces, starting from the President to combatant commanders?

The operational branch of the chain of command is specifically designed to employ forces and direct their operational capabilities in military engagements. This branch flows from the highest civilian leadership, starting with the President, who serves as the Commander-in-Chief, down to the combatant commanders who are responsible for managing military operations across various theaters of war.

In this structure, the operational branch allocates forces and resources to specific missions and ensures that the strategic objectives determined by the President and the Secretary of Defense are implemented effectively at the tactical and operational levels. This includes decisions regarding troop deployment, engagement rules, and mission objectives, which are critical for achieving overall success in military operations.

Understanding the distinct roles within the chain of command helps clarify how responsibilities and authorities are delineated, ensuring a coherent framework for employing forces in response to national security interests.
