Like its predecessors in the series, this book is an epic chronicle of previously unpublished topics, including the uniforms and equipment of the submarine force, PT boat squadrons, mine warfare men, gun crews, signalmen, and more. In addition, never-before addressed subjects including the U.S. Coast Guard, Merchant Marine, Public Health Service, Coast and Geodetic Survey and the Samoan Fita-Fita are examined. Clothing, accoutrements, insignia, small arms, knives, life jackets, novelty items and sweetheart jewelry are all covered.
