"An excellent, balanced history of the 23rd Special Troops . . . may be one of the most important books to come out of World War II." — Engineer Magazine No history of the war in Europe has ever taken into account the actions of the men of the US 23rd Special Troops. These men took part in over twenty-two deception operations against the German army. Some of these operations had tremendous impact upon how the battles in Europe were fought. The men who participated in these actions were sworn to secrecy for fifty years and are only now willing to talk about their role. The 23rd was composed of four main units. A signal deception unit to broadcast fake radio signals, an engineer camouflage unit to set up rubber dummies of tanks and trucks, a combat engineer unit to construct emplacements and provide local security, and a sonic deception company. The sonic unit was developed to fool German listening posts by playing audio recordings of various sounds, such as tanks moving up or bridges being built. The 23rd was the only tactical deception unit of the American Army in World War II combining all aspects of deception. This book also covers the birthplace of sonic deception, the Army Experimental Station at Pine Camp, and the 23rd's smaller sister unit, the 3133rd Sonic Deception company that saw action for fourteen days in Italy. "Highly recommended reading as being a simply fascinating military history of a hidden aspect of World War II that would have a profound and lasting influence on military strategy and tactics." — Midwest Book Review
