The report describes how military missions require an understanding of not only how to perform actions at the right place but also how to perform actions at the right time when the conditions are good enough. The time is therefore just as important as the place for actions. The report consists of three parts. The first part describes how time is experienced by humans in different situations and how time can be modelled to create guidelines for system design and thereby more efficient decision support systems. Some suggestions are made and illustrated for how time can be used for increased control and efficiency. Part two describes research within temporal perception, that is the psychological mechanisms that are used to create subjective time. The section describes the characteristics of subjective time, factors that affect subjective time, established models of subjective time and neuropsychological studies of anatomical structures. Since subjective time in military missions is not as clear cut as in basic research more studies are needed of the exact role of subjective time. The final part analyses missile shots in simulated beyond visual range combat for a better understanding of what factors to include in the calculation of threat levels based on temporal relationships. The analysis shows that in addition to velocities and distance the calculation should also include altitude difference, heading difference and angle of missile shot.
