Throughout history, one of the important battlefield rules has been to use cooperation to divide and gather to win and disperse. Countless war practices have demonstrated a simple truth: a well combined military force with high consistency in action often leads to victory. Currently, the combat style is evolving towards integrated joint operations based on the network information system, and it is necessary to gradually generate joint combat capabilities. Against the backdrop of the leapfrog development from mechanization to informatization and intelligence, forming a pattern of military commission management, theater of operations, and branch building, the new era of composite training has emerged, presenting distinct characteristics of the times compared to the past. The new expansion of the concept connotation of composite training in the new era aims to generate and improve contract combat capabilities, cross service collaborative action capabilities, and create a plug and play module for joint operations. The core essence is to follow the law of systematic military training, based on the support of network information system, with command and action coordination as the main training content, focusing on grouping and adversarial training in the basic form, and cross domain collaborative training as an important expansion direction, focusing on the key abilities of generating "unity", connecting the key points of "unity", and forging new quality abilities of "battle". Synthetic training aggregates the effectiveness of basic training, supports the development of joint training, and has a unique functional positioning and training direction. The subject of group training is more diverse, covering multiple levels and no longer limited to a single military branch. It can be led by a certain military branch with the participation of other relevant military branches' elite forces, resulting in a more diverse composition of forces and higher requirements for capabilities. The training targets are more integrated, focusing on task traction, with distinct features of modularity, new quality, and scalability. Often, they can break through organizational units, equip relevant elements as needed, integrate new domain and new quality forces, and combine into a "flexible grouping, efficient linkage, complementary energy gathering" combat functional module. The training content is more focused, highlighting the internal and external coordination of command and action, focusing on cross domain optimization and system release, emphasizing training formation, training modules, training limits, and training boundaries, expanding from planning coordination and on the fly coordination to frontline autonomous coordination, and improving the capabilities of contract combat and cross branch collaborative combat. The organizational approach is more flexible, highlighting grouping and adversarial training, emphasizing the construction of typical combat scenarios based on network information systems, and adopting various methods such as simulation deduction, specialized research and training, and actual military exercises as needed. It can be organized in stages and steps, or implemented in a coherent manner throughout the entire process. The new changes in the basic requirements of composite training are that composite training is located in the middle stage of the generation of integrated joint combat capabilities, directly related to the "basic plate" of troop combat effectiveness generation, and determines the "quality" of integrated joint combat capabilities. In the new era of synthetic training, we must adhere to a development oriented and problem oriented approach, and focus on solving the contradictions and challenges in training coordination, group training, content system, and condition support. Based on the basic principles of consistent combat training, joint training, systematic training, hierarchical integration, innovation driven, technological empowerment, fine management, and intensive efficiency, we should focus on the following requirements. Functional grouping. Focusing on the requirements of joint combat capabilities, based on specific combat tasks, scientifically optimize and combine the forces within the combat organization. Usually, based on actuarial calculations and simulation verification, different functional requirements are identified and needs are clarified, highlighting the empowerment of new domain and new quality forces. A relatively independent, flexible and plug and play command and action module is constructed, exploring dynamic reorganization of formations based on combat processes and autonomous adjustment of formations based on real-time situations. Cyberization support. Emphasize the use of network information systems to organically link combat elements and units distributed across a wide area, comprehensively connect to the battlefield situation, and solve the problems of command communication, situation sharing, and information exchange. Emphasis should be placed on building a distributed service architecture based on big data technology, embedding and linking various participating forces, researching and training frontline teams and major weapon data hinges, achieving coupling and matching of information power, firepower, and mobility, and shortening the operation cycle of the investigation, control, and evaluation links. Scenario based confrontation. Based on the task plan, construct typical scenarios and organize both the red and blue teams to conduct adversarial training according to their respective task objectives, composition, and principles. Design combat scenarios that are compatible with mission plans and actual battlefields for diverse tasks in different battlefield environments, simulate opponents realistically, train "one process" actions according to task grouping and progress, innovate the application of combat methods, test key capabilities, and enhance the combat capabilities of troops in typical battlefield scenarios. Autonomous collaboration. Focusing on the expansion from planned coordination and on-site collaborative operations to frontline autonomous collaborative operations, based on unified coordination rules, with a focus on command and action coordination, we aim to strengthen the elements, units, and cross domain formations that support joint operations. Focusing on the same goal or objective, real-time sharing based on the battlefield situation, and using collaborative authorization and rule methods, highlighting task planning, force restructuring, and action coordination, training command, coordination, and tactics, to enhance the front-line autonomous coordination capability of the troops. Accurate evaluation. Pay attention to establishing a scientific evaluation index system, innovate the use of "data+situation" evaluation methods and means, accurately evaluate the entire training process, and test and improve the level of synthetic training. Focusing on the operational efficiency of the command system and key operational capabilities, constructing evaluation models, optimizing evaluation rules, collecting real-time data, and emphasizing the use of information-based training evaluation systems to accurately evaluate the combat capabilities and composite training quality of trainees. Our military has always attached great importance to the exploration and practice of group training methods in the implementation of a new model of composite training organization. One important aspect of deepening the transformation of military training is to innovate training models that conform to the laws of combat effectiveness. We should grasp the characteristics of synthetic training in the new era, follow the basic laws of combat power generation from low to high, from scattered to clustered, and gradually integrated. We should strengthen unit integration training, tactical coordination training, and adversarial testing training. Unit integration training. The main approach is to use comprehensive integration methods to organize the various components of combat units and combat elements, and conduct overall training based on network information systems for functional coupling and capability aggregation. This generates the ability to improve the overall capability of combat units and the special action capability of combat elements, achieving the goal of "grasping fingers into fists". This training mode focuses on the organic aggregation of strength elements, solving the problem of consolidating basic module capabilities. It can be divided into two organizational forms: integrated training of combat elements and integrated training of combat units. The integrated training of combat elements emphasizes vertical integration, organized according to methods and steps such as network construction, specialized training, and comprehensive exercises. The integrated training of combat units emphasizes horizontal integration and is organized according to the methods and steps of module self training, combination training, and system joint training. Tactical coordination training. Mainly integrating into specific tactical backgrounds, organizing two or more combat units, conducting command and action coordination training based on battlefield situation sharing and unified coordination rules and standards for functional complementarity and capability upgrading, improving the front-line autonomous coordination ability of the troops, and achieving "combination boxing". This training mode focuses on the coordination and linkage of military actions, solving the problem of frontline autonomous collaboration. According to the formation and application of combat forces, they can be divided into two organizational forms: intra branch and cross branch. They are usually organized and implemented according to methods and steps such as simulation and deduction research, special action training, and multi domain linkage exercises. Simulation and deduction research mainly focuses on the study and deduction of collaborative actions, optimizing collaborative relationships, resolving collaborative contradictions, and improving collaborative rules. Specialized action training mainly focuses on key and difficult issues for specialized refinement, proficient in collaborative action, and laying a solid foundation for collaboration. Multi domain linkage exercises highlight the integration and sharing of multiple sources of situations, multi-dimensional battlefield space control, and coordinated strikes among multiple military branches, enhancing the effectiveness of command and action coordination. Adversarial testing training. The main objective is to establish conditions for practical confrontation testing, organize combat units and elements, and conduct comprehensive or specialized action confrontation exercises based on combat tasks and capability standards, in accordance with actual combat formations and processes, to test and improve practical combat capabilities, highlighting the importance of "real combat, real resistance, and exploration". Usually, a guidance and adjustment mechanism is established, which is implemented according to the steps of scheme design, inspection preparation, inspection implementation, and review and evaluation. This training mode focuses on the verification and improvement of overall abilities, addressing the issues of ability assessment and battlefield access. According to the construction method of testing environmental conditions, it can be divided into two organizational forms: virtual real combination confrontation testing and live fire tactical testing. The combination of virtual and real adversarial testing mainly adopts methods such as system simulation adversarial, red blue autonomous adversarial, and mutual adversarial adversarial; The actual live fire tactical testing mainly adopts the methods of single branch live fire testing, multi branch live fire testing, and multi service live fire testing. The new requirements for the guarantee conditions of synthetic training in the new era are innovative practices for our military to actively adapt to war and actively design wars. To support the high-quality and efficient implementation of synthetic training on a regular basis, it is necessary to introduce the latest technological achievements into the training ground, adhere to the two pronged approach of revitalizing potential and expanding construction, and provide troops with support conditions that are higher than the battlefield and stronger than their opponents. A fully functional training base venue. Focusing on solving the contradiction between the high demand for training venues and the shortage of resources, uneven distribution, and insufficient use, we will accelerate the construction of training base venues that complement each other's advantages, share and utilize technology. We will focus on strengthening the construction of large-scale training bases, new domain and new quality training venues, and typical simulated battlefield environments, emphasizing regional coordination and functional integration, strengthening overall allocation and intensive use, and maximizing the efficiency of limited resources. A compatible and interoperable network information system. Focusing on solving the problem of insufficient network support for command and communication, situational sharing, and data exchange in multi domain and wide area spaces, we aim to create an integrated training network information system. On the one hand, it is necessary to highlight command and communication, situation sharing, data exchange, etc., and build a network communication environment; On the other hand, it is necessary to discover problems through training, provide feedback to promote relevant network information construction, and facilitate two-way interaction between construction and training. A practical training environment closely related to the task. Focusing on solving the problem of inadequate fit between synthetic training environment conditions, tasks, and scenarios, integrating battlefield space and technological achievements, we aim to create a realistic and rigorous training ground. Build similar battlefield conditions, simulate complex adversarial environments, improve the battlefield target set, and create conditions for the troops to "immerse themselves in" actual combat training to the maximum extent possible. A specialized blue army that combines reality and virtuality. Focusing on solving the contradictions of insufficient strength and inadequate capabilities of the Blue Army, and building a specialized Blue Army. Based on the evolution of war forms and in-depth research on opponents, we will coordinate different types of training needs, build simulated adversarial forces, and comprehensively create a "sharpening stone" that looks more like a god from combat ideology and tactical application to weapon equipment and capability level. Advanced and practical simulation system. Accelerate the construction of a fully functional simulation system with a focus on addressing issues such as insufficient means of support, limited system functionality, and low training efficiency. Improve the system platform for military chess deduction and combat experiments, and build a synthetic training simulation environment that is applicable to multiple military branches and covers all fields. Equivalent live fire testing conditions for bottom support. Focusing on addressing issues such as outdated testing methods, loose standards, and detachment from actual combat, we will comprehensively use equidistant equivalent methods to test the baseline boundaries of combat capabilities; Develop high-performance simulators, low-cost targets, etc. to support the regular implementation of confirmatory training; Establish sound guidelines for live fire exercises and standardized military operations to ensure safe organization of training. Deepening composite training is a complex system engineering that should implement the concept of systematic training, meet the requirements of joint operations and training, break through the old mode of closed training for military branches, improve training content, standardize training organization, transform training modes, build training teams, and provide supporting training support, in order to standardize and promote the innovation and development of our military's composite training
