Future international military operations will be more complex than traditional operations undertaken by just one nation; military units from different nations will have to cooperate with not only with each other but also with local governments and civil organizations in order to reach common goals and to ensure a shared understanding of each other’s task and domain responsibility. One characteristic of such endeavors is that each organization brings with it its own information and communication systems. Interconnecting these communication systems will lead to an increase in the total amount of information available to users of these systems. One of the main challenges when building an information infrastructure to support such operations is to ensure information superiority; all users must get access to the information they need to perform efficiently, while at the same time avoiding that the user is flooded with irrelevant information. Making sure that only relevant information is transmitted is even more important in tactical systems, where communication resources are very limited.
