In 1902 when Lt. Ridley McLean first wrote this "sailor's bible," he described it as a manual for every person in the naval service. One hundred years later, it continues to serve as a primer for newly enlisted sailors and as a basic reference for all naval personnel--from seaman to admiral. New technology is artfully blended with ancient heritage, facts and figures are augmented by helpful advice, and the mysterious language of the sea is preserved and deciphered in a volume that has served the United States Navy for an entire century. Updated throughout, the book provides the latest Navy ratings, uniforms, ships, aircraft, and weapons as well as current Navy policies on hazing, fraternization, education, and physical fitness, and a completely new chapter explaining the Navy's mission in terms of its rich heritage. The author, winner of the Alfred Thayer Mahan Award for Naval Literature, has served the Navy in many capacities, both as an enlisted man and officer, and he brings that experience and his devotion to the service to these pages. He explains new terms and such concepts as leadership and core values in both inspiring and pragmatic terms. Relevant photographs, diagrams, and tables enhance the presentation, and accompanying appendixes include a glossary and a wealth of reference material that every sailor will want to keep at hand.
