Step-by-step explanation:
The Chairman of the Joint Chiefs of Staff (CJCS) provides guidance and direction to the Combatant Commanders and the Service Chiefs for the preparation of plans to accomplish tasks and missions using current military capabilities. The CJCS is a key figure in the U.S. military hierarchy and serves as the principal military advisor to the President, the Secretary of Defense, and the National Security Council. As part of the national security apparatus, the CJCS plays a crucial role in formulating military strategy and policy, which is instrumental in maintaining the United States' military powers and ensuring civilian control over the armed forces as established by the Constitution.
Combatant Commanders are responsible for conducting military operations in their respective areas of responsibility using the resources provided by the Service Chiefs from the Army, Navy, Air Force, and Marine Corps. The role of the CJCS is central to aligning military efforts with the broader strategic objectives of the United States, as prescribed by the civilian leadership, including the President who is the Commander in Chief of the armed forces.
Moreover, the CJCS's responsibilities include overseeing strategic planning and advising on matters that could impact the global order, such as global resource competition and potential threats. Ensuring readiness to win conflicts through the application of force or strategic superiority remains a priority for the military sector under the guidance of the CJCS.
