It is reported that a certain air force base has given full play to the effectiveness of modular formation in system training, flexibly allocated various standardized combat modules, and has more and more combat methods against the enemy, with more and more tacit coordination, greatly improving the quality and efficiency of training. This once again shows that the modular grouping of all operational elements is conducive to optimizing the force distribution and maximizing the operational effectiveness of each operational unit and element, both in daily training and in actual combat. Combat should be integrated into the system, and soldiers should be trained in integrated modules. Modern war is a confrontation between systems. Modular grouping means that the combat forces are divided into standardized modules according to the combat functions, and then flexibly combine each module like "building blocks" to form different combat systems. The well-trained standardized modules, through splicing and combination, will build a variety of combat systems with different functions. On the battlefield, the commander "measures the enemy's forces according to the enemy's strategies" and quickly selects one or several suitable combat systems according to the combat tasks and the battlefield situation, just like a boxer's "combined fist", which can maximize the aggregation of superior forces and form a "potential difference" against the enemy. In future integrated joint operations, the participating forces will be more diversified and the tasks will be more diverse. It requires that the troops have stronger adaptability, faster deployment of troops, and more free space for commanders to play. This requires a more flexible and flexible formation mode. In recent years, all major military powers have been actively exploring and promoting modular formation. Our army is also constantly optimizing the scale structure and force formation. The characteristics of the army, such as downsizing, integration, miniaturization, modularization and versatility, are becoming more and more prominent. In the face of the new trend of accelerating the evolution of modern war forms and the new trend of the development of the army formation in the direction of enrichment, integration, multi-function and flexibility, modular formation has increasingly become an important way and a key move to improve the combat effectiveness of the army. In the future battlefield, whether each independent combat module can be combined into a force will have a decisive impact on the victory or defeat of the battlefield. If each module is well trained but lacks coordinated operation, even if it is correctly organized, it will not be able to exert its real power. This requires commanders at all levels to firmly establish a systematic operational thinking, adhere to the task-oriented approach, read the word "union" and play the word "combination" well. Let the mission become a "fusion agent" to increase the rapid cooperation ability between modules. Each combat module should be organized according to the needs of the mission and fight around the mission. At the same time, the standards of all elements in the modular formation should be unified and the rules should be universal. In the aspects of battlefield planning, plan formulation, and coordination, a "picture, a ruler, and a table" should be formed to prevent the "incompatibility" of the module combination and the unsmooth field command, and truly realize the upgrading and transformation of the generation of combat power from "addition" to "multiplication". Modular marshalling is not something that is programmed and patterned. It is not an overnight achievement to integrate all modules into one and grasp fingers into fists. Commanders at all levels must focus on the new situation, new characteristics and new requirements of multi-dimensional operations, pay attention to the combination of virtual and real operations, create a joint battlefield environment, do a good job in contract tactical training and combat organization training, strengthen each module and each system, adhere to what kind of organization is needed in the future battlefield, find answers in realistic pre practice, play a good "combination fist" of modular organization, and always maintain our "spear" ratio on the battlefield
