In order to enhance the overall protection capability of nuclear, biological and chemical war (NBC) in joint operations, the implementation of intelligent NBC protection support in intelligent war is studied. Intelligent thinking is reasonably applied to nuclear, biological and chemical protection support, and 5 major issues of ‘information acquisition, threat determination, hazard assessment, action decision-making and equipment personnel’ are analyzed. The results show that the ‘intelligent’ nuclear, biological and chemical protection support can avoid and reduce nuclear, biological and chemical hazards, and enhance the sustained combat support capability of the support forces.
