Army information-firepower warfare will be more important in the future operation, in order to satisfy the needs of information-firepower warfare simulation, the problem of conceptual modeling of army information-firepower warfare is studied. Basic concept and modeling process of military conceptual modeling is described, based on the formative description of army information-firepower warfare, the method of unified modeling language (UML) was used in formalization description and the static conceptual model and the dynamic conceptual model of army information-firepower warfare are established. According to build the conceptual model, the communication between military personnel and technical developer is realized and the foundation of army information-firepower warfare simulation is laid.
