Consideration to computer generated force for defence systems

Nowadays military training needs effective techniques, especially in a country that has fewer opportunities to train the forces using real entities (i.e., Japan). Considering this situation, a virtual training system is one of the solutions to bringing up military skill. The virtual training is based on simulation techniques to cope with varying battle situations. The paper introduces CGF (Computer Generated Forces) which gives trainers varying situations in combat training. In the simulation, CGF acts as a self-adjusting force against the trainer´s entity control action, where the entity expresses weapons. A construction of CGF applied simulation is discussed and some examples are introduced
