Military deception is probably as old as war itself, but the earliest photos of dummy weapons date from the 1861-65 American Civil War, when “Quaker guns” (pictured) were used by both sides. The “guns” were in fact logs, mounted to give distant, telescope-squinting generals a false impression of firepower.
