Abstract: In order to help commanders understand battlefield environments much better and more quickly, then respond rapidly to the dynamic changes of the environments, this paper makes researches on the grouping of operational entities. With the combination of searching abilities in GA and merits of knowledge acquisition and maintenance in CBR, the paper proposes a new grouping method. By aggregating operational entities into operational groups, the method can greatly alleviate the cognitive pressure of commanders and improve their decision efficiency.
