Which best describes the two distinct chains of command used by the President and the Secretary of Defense?

• A. Operation chain (POTUS-SECDEF-CCD R) and Administrative chain (POTUS-SECDEF-Secretaries of mil dep)
• B. Strategic chain and Tactical chain
• C. Line of succession and Control chain
• D. Emergency chain and Supply chain

Answer: (A)

The question tests understanding that there are two separate command tracks for the military: an operational chain and an administrative chain. The operational chain is the line of authority used to direct military actions and combatant operations. It runs from the President (as Commander in Chief) to the Secretary of Defense and then to the Combatant Commanders who execute missions. This structure keeps clear who commands operations in the field. The administrative chain handles the support, personnel, and resources across the services. It goes from the President to the Secretary of Defense and then to the Secretaries of the Military Departments (Army, Navy, Air Force/Space Force, Marine Corps). This separation ensures service-specific management—such as personnel, budgeting, and logistics—remains organized within the branches themselves. Together, these two chains maintain both effective strategic control of operations and proper administrative oversight. The described option reflects this real distinction: an Operation chain and an Administrative chain with the described participants.
