The Naval Officer's Guide is a collection of information and advice intended primarily for officers in the US Navy, but it also provides a valuable introduction to the sea services for officers of other uniformed services, members of the U.S. interagency community, naval history buffs, and anyone interested in learning more about the Navy. Completely revised and updated, this edition reflects the significant recent changes in the organization and policies of the Department of Defense and the Navy. This revision reflects changes in the Navy operating environment resulting from the rise of irregular challenges, increased emphasis on joint and interagency operations, introduction of numerous technological innovations, and the natural evolution of traditions and social norms. Topics covered include current operational Navy doctrine and policies, career planning and personal records administration, shipboard routine and protocol, the operational and administrative organization of ships and staffs, the organization, missions and functions of each of the armed services, composition, management and administration of enlisted members, leadership, communications, and preparation for command at sea.
