This book looks at the history of the trained officers and men who went by the cover name "Beach Jumpers". Their top-secret mission was to create and sustain the illusion that a military landing was imminent at Beach "A" when in fact US/Allied troops would hit the beaches 100 miles away at Beach "X". During World War II their tactics were extremely successful in Sicily, Salerno, Southern France and the Philippines. Beach Jumpers later served ashore and afloat in Vietnam. Their descendents, called "Fleet Tactical Deception Groups", continue their classified work today. This book details the development, major operations, weapons and leaders of the group. The Beach Jumpers began as a naval task group under the direct control of the fleet commander and consisted of specialists, officers and men, trained to conduct tactical cover and deception missions, to include radio and radar countermeasures.
