Re-blog for Tim.
The Ghost Army was a United States Army tactical deception unit during World War II officially known as the 23rd Headquarters Special Troops. The 1,100-man unit was given a unique mission within the Army to impersonate other U.S. Army units in order to fool the enemy. From a few weeks after D-Day, when they landed in France, until the end of the war, they put on a traveling road show, using inflatable tanks, sound trucks, phony radio transmissions and even playacting. Their mission was kept secret until 1996, and elements of it are still classified.
