New forms of suppressive gunfire decoys are provided. In some aspects, a pin-pull device may be used to program and adjust several settings of the decoy devices, activating such devices immediately before deployment. In some aspects, the pin-pull device may serve as a remote control unit. In a preferred method of deployment, the devices are thrown to a location different from that occupied by the user(s), simulating another source of gunfire, distracting and misleading an enemy, and providing the effects of suppressive fire. In some embodiments, a networked computer system(s) may be used as a remote control unit, and the decoy device may include cameras and other sensors for tactical surveillance. In still other aspects, the gunfire decoy device may be capable of locomotion, and may be self-relocating in response to certain commands, or in reaction to stimuli, to confuse the enemy regarding sources of gunfire and troop locations.
