Abstract: Muzzle flash simulators that combine visual, audio, and thermal signals synchronized to the firing of a rifleman's weapon to obscure his position by producing the illusion that the shot came from a location other than the rifleman's actual location. The system may be deployed by placement with a removable ground penetrating spike, by use upon a tripod mounting system, by a hanger or by launching upon a projectile. The simulator is remotely operated. The simulator can be deployed as a single unit or as a set of units operating in coordination.
