Who are the advisors at the National Security Council (NSC)?

The National Security Council (NSC) primarily includes the heads of the key executive departments and agencies involved in national security. While various advisors can be involved in NSC discussions, the primary military advisor to the President in the context of military operations and strategy is the Chairman of the Joint Chiefs of Staff (CJCS). The CJCS plays a critical role in coordinating military advice and representing the views of the entire military establishment, which is vital during national security discussions.

The other options mentioned include other key figures in national security; however, they do not exclusively serve as advisors at the NSC in the same manner as the CJCS does. The Secretary of Defense and Secretary of State, despite being influential in national security matters, primarily focus on their specific departmental responsibilities and are not the sole representatives for military advice at the NSC.
