The invention concerns a method for associating an object of a second type with at least one object from a group of objects of a first type. The method is to be used in combat exercises and the above mentioned objects are players and weapons. According to the method, a signal containing the identity of the object is transmitted from each object in the group, whereupon the transmitted signals are received by the object of the second type, and the received signals are analyzed. The object of the second type is then associated with at least one preferred object in the group on the basis of the signal analysis, whereupon any previous association(s) of the object of the second type with objects of the first type is/are taken into account in the associating process. The invention also includes a device for a receiver arranged so as to realize the foregoing method.
