Who has executive authority over the Combat Support Agencies?

The correct answer is that the Secretary of Defense holds executive authority over the Combat Support Agencies. This position is crucial because the Secretary of Defense is responsible for the overall direction, control, and management of the Department of Defense and its components. The Combat Support Agencies, which provide critical support in areas such as intelligence, logistics, and communications, fall under the broad purview of the Secretary of Defense, who ensures that these agencies align with national defense strategies and priorities.

Other positions mentioned, such as the Joint Chiefs of Staff, primarily serve as military advisors to the Secretary of Defense and the President rather than holding direct authority over Combat Support Agencies. The National Security Advisor focuses on coordinating national security policy but does not have direct executive authority over military operational components. The Chief of Staff of the Army is a key military leader within the Army but operates within the Army’s structure rather than holding overarching authority over all combat support functions across the military branches.
