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.
