During World War II, the United States Army formed a very unique and interesting unit called the 23rd Headquarters Special Troops, otherwise known as the Ghost Army. No, the US Army did not grab an ouija board to summon the fallen and re-recruit them (as far as we know, at least). This unit held an important mission in the Normandy Landings. Their main weapon? An inflatable tank and a whole lot of wild imagination. We’re not joking.

Before the Invasion

Before the Allied forces rushed to the coast of Normandy, the US Army recruited a total of 1,100 people from art schools, advertising agencies, and other fields of work that foster creative thinking. They were artists, architects, actors, set designers, and engineers. They assembled the 23rd Headquarters Special Troops with the main purpose of misleading, deceiving, and befuddling the German Army. They were equipped with dummy tanks and artillery, fake aircraft, and giant speakers to broadcast the sounds of men and artillery to trick the Germans into thinking it was upwards of a two-division 30,000-man force. Above all, the mission was classified and remained so for 40 years until it was revealed to the public in 1996.

This course of action was inspired by the deception technique that the British did in the battle of El Alamein in late 1942 called Operation Bertram.

On June 6, 1944, exactly on the first day of the D-Day Invasion, the First Army landed and engaged with the German forces on the coast of Normandy. The Ghost Army started their work in the background. Their tasks were divided by their combat units depending on the type of deception they were assigned to do: sonic deception, radio deception, visual deception, and the collective atmosphere.
