The Russian Army will soon be cutting costs with an old trick used by the Allies in England to fool the German military during World War II.

The Russians have invested in giant blow up decoys created in order to give the enemy a false impression when viewing Russian defenses in aerial or satellite photos.

The material used in the construction of the models even fools enemy radar and tricks thermal imaging sensors into thinking that they're real, since they carry the same heat signatures as the real ones.

The inflatables weigh about 200 pounds each, inflate in minutes, and look like the real deal from far away.

Besides tanks, the giant mockups include an S-300 missile launching truck, MiG fighter jets and even entire radar stations.

The only difference is that if these decoys are bombed or struck by a missile, they cost only about $10,000 each to replace versus several million dollars to replace war munitions.

The war decoys are made by the same company that makes hot-air-balloons and toys for children.
