Which branch of the chain of command begins with the President, goes through the Secretary of Defense to the commander of a combatant command, and then to the Marine Corps component commander?

• A. Strategic chain of command
• B. Administrative chain of command
• C. Tactical chain of command
• D. Operational chain of command

Answer: (D)

Operational chain of command connects national leadership to the forces that execute campaigns. The President, as Commander in Chief, sets the strategic objectives and, through the Secretary of Defense, channels authority to a Combatant Command. The Combatant Commander then directs the forces assigned to that command, down to the Marine Corps component commander, who carries out the missions in coordination with other services under that command. This flow ensures unity of effort in executing operations and links strategic intent to on-the-ground action. Administrative control handles service-level support and personnel matters, while tactical control concerns direct, in-theater actions at the unit level.
