1. Features: 1. Integrated command and control, highly integrated information. Information warfare is fast-paced and short-lasting, and fighters are fleeting. Only by obtaining and processing all kinds of battlefield information in time and making judgment and disposal quickly can joint command and control be effectively implemented. It can be seen that real-time command and control is becoming more and more important. Therefore, the armed forces of developed countries attach great importance to the development of advanced information command and control systems, and realize the real-time integration of intelligence reconnaissance, early warning detection, information transmission, information processing and command and control. For example, the US military is committed to building a "GIG", and plans to connect millions of nodes into a network to realize a "seamless information link" from sensors to shooters, from military commanders to foxholes, and emphasizes the use of "network-centric warfare" to develop joint operations centered on weapons platforms into integrated operations centered on information networks. In order to improve the adaptability of the command system, relying on advanced information technology, the armies of various countries have changed the vertical tree structure with narrow width and long length into a flat network command system with short width and short length, thus reducing the command hierarchy, shortening the information flow, improving the response speed and enhancing the command efficiency. 2. Combat forces are integrated and combat operations are diversified. Joint operations under the conditions of informationization are manifested in the integration of combat forces and the complementarity of functional advantages in pursuit of maximum overall coordination. The first is the unity of military and political affairs, military struggle, and the struggle on the political, economic and diplomatic fronts. Secondly, the integration of major combat forces, organically combining the forces of various services and arms participating in the war, rationally organizing combat corps, legions or joint forces, and forming an integrated force structure system of various services and arms. The service forces participating in the war are only part of the joint operation, and it is difficult for any service or arms to play a role alone. Only by great alliance and deep alliance can we form a strong and effective combat effectiveness. Then there is the integration of various operations, multi-level operations of strategy, campaign and tactics, non-contact, non-linear and asymmetric operations, information warfare, network warfare and psychological warfare, the combination of "hard strike" and "soft kill", the combination of firepower strike and special operations, and the combination of full-depth three-dimensional operations and precision strike, forming a pluralistic and integrated operational architecture. 3. Combat platform integration, system against decisive battle. Information-based weapons and equipment platform is the material basis for implementing integrated joint operations. Information weapons and equipment is an integrated combat system with computer technology as the core and information technology as the basis. Its composition mainly includes three-dimensional reconnaissance and early warning system, information transmission and processing system, mobile combat weapon system, information attack and defense weapon system, individual digital equipment and command and control system. When the weapon systems and operational platforms of various services are like smoking chimneys and reach the physical limit, people will think of "system integration". All-round integration has brought about the integration of the combat system and the optimization of the structure, thus forming the C4KISR system. The integration of combat platforms makes up for the "shortcomings" of independent services and single weapon systems, and greatly improves the comprehensive operational efficiency. With the help of information technology, different weapons and equipment have achieved complementary efficiency, different services have achieved complementary strength and function, and they have the ability of interconnection and interoperability, so that different weapon systems of different services are integrated in technology and operational time and space, and system confrontation has become the main body of joint operations. In the information war, the offensive and defensive confrontation based on C4KISR system will become the main combat action, which is also the key to determine the outcome of the war. The battlefield is multidimensional, and the field of confrontation is vast. In the era of mechanization, the services are relatively independent, and the armed forces dominate their respective battlefields, and the combat operations are basically carried out in the three-dimensional space of land, sea and air. In information-based joint operations, the combat space will expand from the traditional three-dimensional space to multi-dimensional space, from limited space to infinite space, and from tangible space to intangible space. The opposing sides will fully confront each other in the vast fields such as land battlefield, sea battlefield, air battlefield, space battlefield, electromagnetic battlefield, network battlefield and psychological battlefield. Any combat action that takes place in this combat space will not be a single battlefield contest, but a multi-dimensional joint combat action. Every battlefield space plays an indispensable role. Any single battlefield space is restricted and influenced by other battlefields, and any combat action can not be separated from the support of air, space, network and electromagnetic information. Especially in the field of space and information, the struggle will become more and more fierce. As two important strategic commanding heights in modern warfare, space and information fields have broken through the boundaries of traditional territories and played an irreplaceable role in joint operations. Fighting for "the right to control the sky" and "the right to control the information" will become the "winner" of the contest between the opposing sides. 4. Operational support is integrated to ensure accuracy and efficiency. Joint operational support refers to various support measures and actions taken to ensure the smooth implementation of combat tasks by troops, mainly including operational support, logistics support, equipment support and political work support. In the past, there were obvious boundaries and differences between operations and support, and various support businesses were relatively independent. In information-based joint operations, operations and support have moved from separation to integration. Support is not only an important part of combat, but also determines the success or failure of combat to a certain extent. In addition, the concept of precise guarantee is also a prominent feature of comprehensive guarantee. In other words, relying on the information-based combat, logistics and equipment support system, under the premise of optimizing the allocation of resources, the troops are provided with appropriate and accurate support at the right time and place, which greatly improves the support efficiency and sustained combat capability. Second, status: ① Joint operational command is the most essential dynamic element in combat effectiveness; ② Joint operational command is an important factor to transform the operational potential of joint forces into actual combat effectiveness; ③ Joint operational command is the key to change the strength contrast and improve the efficiency of joint operations. Three. Supplement: The characteristics of joint operations under the condition of informationization are long-range, rapid and precise strike, which requires the integration of multiple services and arms, effectively achieving precise command, precise control, precise coordination and both offensive and defensive. All information weapons and equipment systems must be supported by high-precision frequency sources to unify "military standard time".
