The Secretary of Defense may assign CJCS responsibility for overseeing the activities of which group?

• A. Combatant Commands
• B. The Joint Chiefs of Staff
• C. The National Security Council
• D. DoD Agencies

Answer: (D)

The Secretary of Defense can designate the Chairman of the Joint Chiefs of Staff to oversee DoD Agencies. DoD Agencies are internal support organizations within the department that perform specialized functions across the defense mission. Having the CJCS oversee these agencies helps ensure their activities are coordinated with joint military requirements and DoD-wide priorities, providing a unified approach to how supporting functions operate in tandem with the armed forces.

The other options don’t fit this kind of oversight role. Combatant Commands are active warfighting commands that execute operations and report through the chain of command established by the SecDef and the CJCS; the National Security Council is a White House policy body, not a DoD entity overseen by the CJCS; and the Joint Chiefs of Staff is the collective body chaired by the CJCS, not an entity that would be overseen by the CJCS under this arrangement.
