Leathernecks combines a lively, well-researched narrative with a generous selection of illustrations, many in color, and numerous maps to provide a topically and chronologically balanced history of the U.S. Marine Corps from its inception to the present day.

Throughout the first century of its existence the Marine Corps seldom exceeded the strength of an infantry regiment but eventually became more powerful than many armies and developed the world's most potent military mystique. Cameos of some of the individuals who made exceptional contributions to the Corps' rich heritage are included.
