Which group consists of the Secretary of Defense, Secretaries of the Army, Navy, and Air Force?

The group that consists of the Secretary of Defense, along with the Secretaries of the Army, Navy, and Air Force, is known as the Armed Forces Policy Council. This council plays a crucial role in advising the Secretary of Defense on matters related to the policy and readiness of the military services. Its members oversee the broad strategic direction and operational readiness of the U.S. armed forces, ensuring that all branches are aligned with national defense strategies and policies.

The other groups listed do not include all these members together in the same manner. For example, the Unified Combatant Command refers to the various commands that have a specific mission and area of responsibility, but does not include the secretaries. The National Security Council is focused on coordinating national security and foreign policy among government agencies, and the Joint Chiefs of Staff comprises the highest-ranking military officers, not the civilian secretaries. This makes the Armed Forces Policy Council the correct choice as it is the specific group mentioned in the question.
