A soldier (A) carries a weapon, on which a laser device (1) is mounted, which is used for illuminating a harness device (6) on the body of another soldier (B). The laser device and the target device each include a microprocessor as well as an ultrasound unit and/or a radio unit (72, 71) such that, if the laser device does not receive a response from the target device within a period of time Ta following the transmission of a bundled, coded laser beam, it transmits another laser beam with different coding, which causes the ultrasound unit and/or the radio unit of the target device to transmit an acknowledgement which can be received by the ultrasound unit and/or the radio unit of the laser device.
