The Russian military has developed inflatable imitation weapons that require air instead of ammunition.
The inflatable weapons are easy to transport and quick to deploy, and act as an inventive way to deceive the enemy and save money.
The Russian army has an inventory of inflatable weapons ranging from fake tanks to entire radar stations, according to BBC News.
The stand-in decoys are among the most advanced military decoys and are made of a special material that can deceive an enemy radar and thermal imaging equipment into recognising them as real weapons.
The inflatables are stitched at a former hot-air balloon factory and are much cheaper than real weapons.
