Ranks and insignia of NATO navies' officers

This table shows the ranks and insignia of officers and warrant officers in the navies of member countries of NATO. NATO maintains a "standard rank scale" in an attempt to match every member country's military rank to corresponding ranks used by the other members. The rank categories were established in the document STANAG 2116, formally titled NATO Codes for Grades of Military Personnel.
