Which document primarily guides the actions of the Joint Chiefs of Staff?

The National Defense Strategy serves as the primary guiding document for the actions of the Joint Chiefs of Staff because it outlines the strategic direction for the Department of Defense, articulating how military forces should be organized, trained, and equipped to meet national security objectives. This strategy reflects the priorities and direction provided by the President and Secretary of Defense and establishes the framework within which the Joint Chiefs operate to ensure that military readiness aligns with national policies and goals.

The role of the Joint Chiefs is to advise on military matters that directly relate to national defense, and the National Defense Strategy provides that essential link between military strategy and national policy. By defining the challenges the U.S. faces and prioritizing military engagements, this document informs all levels of military operations and preparedness. As such, it is indispensable for ensuring that the Joint Chiefs can effectively perform their mission in supporting national interests.
