Abstract: A weapon training simulation system comprising a firearm with a variable data transmission system mounted therein. The system includes at least one sensor to detect detonation of a blank round in the firearm, a variable data transmitter enabled by said sensor to transmit a signal comprising a weapon identification and, optionally, a direct hit/near miss selection, a power amplifier to amplify said signal, and a laser to project said amplified signal along the boresight of said firearm. The laser is mounted in the barrel of the firearm, and the other electronic components may be advantageously mounted in the handgrip or stock thereof. The system may include a firing counter to disable the transmitter once a number of transmissions equal to the number of rounds in a full load has been made. The system may also include a detector to disable the transmitter in the event that exterior sensors worn by the firearm user report that the user has been struck by laser light from a substantially identical system.

Abstract: A miniaturized laser assembly is mounted on a weapon with the power source and circuitry for the laser assembly being contained within the weapon with no significant visual or actual weight change in the weapons original characteristics. The laser weapon is fired in a normal manner by squeezing the trigger while aiming at the target. The laser emits a harmless invisible signal pulse of coherent light so that if the weapon is aimed correctly a detector indicator unit mounted on a target receives and processes the laser pulse to cause an audible sound signifying that a hit has been registered.
