This is "SECRET SOLDIERS: The Story of WWII's Heroic Army of Deception"
A.K.A.
"SECRET SOLDIERS: How a Troupe of American Artists, Designers, and Sonic Wizards Won World War II's Battles of Deception Against the Germans"
by Philip Gerard.
This is my first serious attempt at converting a physical book to an e-book. I do not believe that an official e-book version of Secret Soldiers was ever released.
I don't support piracy, so this download this only for those who own the physical version, and wish to have a digital backup
