'Kodak' was a US tactical deception undertaking by the 23rd Headquarters Special Troops on the Western Front (22/23 December 1944).
The operation was based on the simulation of radio traffic by Major General Horace L. McBride’s 80th Division and Major General John S. Wood’s 4th Armored Division in a manner designed to confuse the Germans as to which of these were real signals from the two formations.
