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 US interagency community, naval history buffs, or anyone interested in learning more about the Navy. Completely revised and updated, this edition reflects the significant recent changes in the organisation 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 organisation of ships and staffs; the organisation, missions and functions of each of the armed services; composition, management and administration of enlisted members; leadership; communications and preparation for command at sea.
