Fake naval yard

Due to heavy bombardment from the Soviets the Allies developed easily constructable fake buildings which were made to decive enemeies into targeting them to draw attention away from their real counterparts. The fake naval yard could be built to decive an enemy commander into thinking the allies were planning a naval strike, but then the Allies may do a ground strike instead. Even if the Allies were planning to use ships fake naval yards were built just to force the Soviets to waste time and ammo trying to figure out which was the real naval yard.
