  • a water shield is a fan-shaped, in particular semicircular, water surface, which is produced by a correspondingly configured nozzle.
  • the device for producing the non-solid projection surface has in particular nozzles which emit the substance which forms the projection surface.
  • the nozzles are preferably arranged so that they are not visible from the position of the operator of the firearm. Alternatively or additionally, the nozzles are arranged so that the generated projection surface is insensitive to wind.
