To promote the tank element combat simulation efficiency, the system simulates tank element combat by using the method of combat simulation modeling, there are: High Level Architecture (HLA) and Run-Time Infrastructure (RTI) progress. And puts great emphasis on studying from function and characteristic, architecture, working flow, exploitation system are studied. By building FOM/SOM and creating FED files, it puts the axe in the helve that links with battlefield environment federate. Practices shows that the design of system is logical, the circulator is steady, the effect of simulation is vivid，and it can produce military and economic efficiency. The system can satisfy the needs of Training of tank element’s tactics. These models can be used as reference for intellectualized combat simulation.
