In the operational chain of command, who directly carries out the President's directives through SecDef?

• A. Secretaries of the Military Departments
• B. Joint Task Forces
• C. Combatant Commanders
• D. Service Component Commands

Answer: (C)

The main idea here is how presidential directives get translated into in-theater action. The President acts as Commander in Chief and, through the Secretary of Defense, assigns authority to the Combatant Commanders. These CCDRs are the ones who actually plan and direct military operations using the forces assigned to their unified or subunified commands. They hold operational control over those forces, meaning they direct how, when, and where to use them to achieve missions. Service Secretaries provide administrative and support functions for their services, and Service Component Commands deliver forces to the CCDRs, but they don’t exercise the primary operational command themselves. Joint Task Forces can be established for specific operations, but they remain under the CCDR’s command, so the CCDR remains the direct executor of the President’s directives.
