Metropolitan Area. The Commandant is currently the only remaining Naval Districts from the 1900s era, making it, by default the oldest of the current naval regions. The Commandant is headquartered at the Washington Navy Yard only a few yards away from the Commander, Navy Installations Command headquarters.
