In order to enhance the ability to deal with violent conflicts and establish an effective counter-terrorism force, the DoDAF is used to design an overall structure of the air-ground unmanned platform and the special combat team cooperative counter-terrorism system. Based on the task background of special attack mission, the viewpoint model of special combat system is established to describe the whole framework in a standardized and systematic way. The results show that the design can provide formal description for military conceptual modeling, and has reference value for the top-level design of manned/unmanned cooperative counter-terrorism system.
