Wartime U.S. Navy insignia worn by commissioned officers, warrant officers and chief petty officers is featured with concise descriptions and detailed photographs. Additionally, a complete catalog of enlisted men's rating badges and distinguishing marks are showcased in brilliant full color with detailed and informative captions. As a bonus, the complete 1941 U.S. Navy Uniform Regulations with all wartime changes and amendments is included on CD-ROM.
