The information-based command and control system is a man-machine integrated system that combines computer-based information technology equipment with commanders to command and control troops and weapons. It is an important high-tech military equipment, it is one of the main symbols of military information, and realizes the automation, real-time and precision of battlefield command. The establishment and effective use of information-based command and control system to maximize the comprehensive effectiveness of combat forces and weapons is the common goal pursued by all countries.

　　At present, the highest form of Information Command and control system is C4ISR system. The C4ISR system is called Integrated Command Control Control Computer Communications Intelligence Surveillance and Reconnaissance. It consists of four parts: sensing, navigation, Command and communication, including Command, Control, communication, Computer, Intelligence, Surveillance and Reconnaissance. The highly integrated and integrated C4ISR system evolved from the C2 system. According to the mission of the system, the C4ISR system can be divided into strategic C4ISR, campaign C4ISR and tactical C4ISR. According to the arms of service, it can be divided into army C4ISR, Navy C4ISR, Air C4ISR and Strategic Missile Force C4ISR. With the improvement of the performance of C4ISR system and various kinds of satellites, the C4ISR system of different levels and different arms will realize intercommunication and information sharing, high level commanders can learn about events around the world at almost any time and place, and pilots of planes, tanks, and even individual soldiers can know their location on earth at any time, and can keep in touch with their superiors anywhere on the planet, it can provide real-time target information for precision weapon, and realize the automation, real-time and precision of battlefield command.　　

　　Tactical training refers to the training of tactical principles and combat methods carried out by individual soldiers to the tactical corps. The aim is to improve the ability of officers to organize and command combat, and to make soldiers skilled in combat action. With the changes of the army’s weaponry, equipment, establishment and system, the tactical training has been developing continuously. A complete C4ISR simulation system should adopt standardized model description method, establish a complete set of C4ISR model base, and provide corresponding modeling tools, monitoring tools, data analysis tools and simulation software development environment. The experiment environment must be able to support the reuse and reorganization of the model, to flexibly generate a set of simulation model framework suitable for the specific C4ISR system according to the operational requirements, and to carry out the simulation experiments on the basis of this framework quickly; It can support the simulation analysis and evaluation of the whole system life cycle from C4ISR system concept design to system development, operation use and system optimization upgrade. Therefore, the simulation environment should have enough adaptability and stability, and it can flexibly meet the simulation requirements of various C4ISR systems. Taking the air combat simulation system as an example, C4ISR system is one of the key technologies of modern air combat. It combines the platforms of air fighter, UAV, early warning aircraft and ground command and control center into a network, and forms platform cooperative combat. But the higher level of synergy is the synergy of weapons, such as multi-aircraft multi-target cooperative attack and multi-aircraft missile cooperative guidance, namely C4kisr, where k (KI11) is the kill; C4KISR can enhance the control capability of weapon systems, it is an important means to improve the operational efficiency of weapon platform and hit rate of ammunition.
