Andaman and Nicobar Command is

The Andaman and Nicobar Command (ANC) is India's first and only operational tri-service integrated theater command. Established in 2001, it is headquartered in Port Blair and brings together the Indian Army, Navy, Air Force, and Coast Guard under a single unified commander. Unlike other regional commands that report to their respective service headquarters, the ANC operates directly under the jurisdiction of the Chiefs of Staff Committee (CoSC), which is now coordinated through the Department of Military Affairs and the Chief of Defence Staff. While the provided snippets describe the geography of the islands and the President's role as Supreme Commander [2], they do not detail the command's structure. The ANC's primary role is to protect India's strategic interests in the Bay of Bengal and the Malacca Strait, ensuring maritime security and surveillance across the 556 islands in the archipelago .
