Chairman of the Joint Chiefs of Staff
Explanation:
Nevertheless, all JCS members, by statute, are intelligence officers and may respond to requests or willingly send, by means of the Chairman, advisories, or recommendations to the Chairperson, the Defence secretary or the NS Center. The Chairman, nevertheless, is the Chairperson of the Joint Chiefs of Staff.
The Joint Chiefs of Staff have changed their executive power. In the Second World War, the United States Joint chiefs of staff served as administrators of theater and field commanders, although they did not consider Joint Chiefs of Staff to be Commander Combative Commanders but the initial National Security Act of 1947 treated them as planners and advisors.
