A device for improving performance and improving assessment in a combat training center includes light shot simulators with weapon-linked transmitters and/or transceivers as active equipment and personal or passive equipment of exercise participants, with light-signal receivers and decoding electronics as well as GPS equipment assigned to a person and/or exercise device, for a determination of position, as well as radio equipment of the persons and/or the device, for bi-directional communication with a central administration. The light-signal receivers are equipped for additional detection of the position of the exercise participants in rooms/buildings and vehicles, by means of the reception of signals from light-optic angle transmitters.
