Army contract combat is the main form of combat for the army, and it is crucial for the fight for control of the land battlefield. Currently, with the rapid development of information technology and the deep application of artificial intelligence, the form of modern warfare is undergoing profound changes. Intelligence not only improves combat efficiency, but also redefines battlefield rules, promoting new development trends in combat subjects, combat deployment, combat procedures, and collaborative priorities in Army contract combat. The main body of combat tends to be diversified. In the past, the main implementers of army contract battles were infantry and armored forces. However, in informationized and intelligent local wars, with the widespread application of intelligent unmanned platforms and technologies, artillery, special forces, unmanned forces, etc. will become the "protagonists" of army contract battles, and the implementers will become more diverse. Firstly, the artillery's main combat position continues to strengthen. With the continuous improvement of artillery firepower strike accuracy, strike distance, and damage effect, especially the establishment and strengthening of the firepower main battle concept, there may be artillery based firepower battles in the future. Secondly, the role of special forces will become increasingly important. Due to their strong operational concealment, wide range of tasks, and outstanding night combat capabilities in close combat, Army Special Forces will closely collaborate with artillery, Army Aviation, and other branches of the military in the future to undertake tasks such as special raids and seizing important targets. Thirdly, the efficiency of intelligent unmanned platforms is becoming increasingly prominent. Intelligent equipment such as unmanned vehicles, drones, and robots are widely involved in combat, participating or leading army contract battles through various methods such as embedding humans, unmanned leadership, and unmanned clusters, greatly improving combat effectiveness. For example, in recent years, both sides have extensively used drones for battlefield surveillance and precision strikes in localized world wars, greatly changing the traditional ground combat mode. Combat deployment tends to be decentralized and dynamic. In the past, the deployment method of combat forces was to occupy positions through maneuvering, gathering, and other means, and then concentrate the troops for deployment. The attacking and defending sides then engaged in a decisive battle in a certain battlefield space. However, with the improvement of the destructive ability, precision strike ability, and rapid response ability of informationized and intelligent weapons and equipment, in order to enhance battlefield survival capability, it is objectively required to adopt a decentralized and dynamic deployment method, forming a non-linear and irregular deployment that combines distance and proximity, high and low, tangible and intangible. One is to pursue evacuation configuration. Fully utilize the shielding conditions of combat space and terrain, appropriately increase the spacing between various force units and firearms, and gradually allocate combat units and support units from the front to the depth, forming a more dispersed configuration space and greatly improving battlefield survival capabilities. The second is to focus on dynamic adjustment. In the era of intelligence, discovery leads to destruction, and each combat unit should promptly, quickly, and flexibly change its configuration area or position to improve its battlefield survival capability. The Russian artillery widely adopts the artillery tactics of "shooting, shifting, shooting, shifting, re shooting, and re shifting" in combat. The rocket artillery unit shifts its launch position every few minutes on average, which not only catches the enemy off guard but also ensures that it is not retaliated by enemy fire. The third is the dynamic aggregation power. According to the changes in the battlefield situation and the needs of combat tasks, tasks are allocated in a timely manner, combat forces are clarified, and dispersed forces are concentrated in designated targets and areas in a dynamic joint manner through methods such as rapid delivery, achieving real-time aggregation of combat power. The combat program tends towards multi domain parallelism. The traditional combat routine is mainly based on the actions of infantry, armored troops, and other forces, presenting a linear process of "attacking layer by layer and peeling off, defending layer by layer and retreating step by step". With the widespread use of intelligent unmanned weapons and equipment on the land battlefield, combat operations will be carried out in multiple domains such as land, sea, air, space, electricity, and network, implementing multi domain synchronized and effective strikes and protection against multiple targets throughout the depth of the battlefield. One is to dominate the combat process based on the firepower killing network. With the support of information network systems, a firepower killing network is composed of unmanned aerial vehicles, patrol missiles, artillery, etc., which coordinate and use various firepower to destroy key points, strike vital areas, and paralyze targets, disperse, disrupt, and weaken the enemy system, thereby controlling the pace of combat, leading the process of combat, and determining the outcome of combat. The second is to adjust subsequent actions based on real-time evaluation. In the era of intelligence, relying on satellites, drones, the Internet of Things, sensors, etc., we can achieve all-weather and multi-dimensional battlefield situational awareness, quickly capture detailed information such as the structure, appearance, function, and quantity of the target, timely evaluate the enemy's target damage situation, the compatibility of the system architecture status with expectations, and feedback the damage situation to various combat units and command decision-making centers to guide subsequent actions. The third is to invest major forces based on advantageous domains. When the enemy's system structure is damaged to a certain extent, in the land or airspace where our own side may gain an advantage, we aim at the areas where the enemy's system functions have been lost, weak areas, deployment gaps, etc., quickly deploy main combat forces, and take precise strikes, three-dimensional assaults, front and rear joint attacks, and other actions to quickly seize and control the target. The focus of collaboration tends to be someone but no one collaborating. In the past, the focus of army contract combat coordination was mainly on the coordination between infantry, armored units, artillery, air defense units and other branches of the military. However, in informationized and intelligent local wars, with the widespread application of unmanned platforms such as drones and unmanned vehicles, the coordination focus has shifted towards the coordination between manned and unmanned forces. One is that cross domain collaboration has become the main content. Army contract battles are no longer fought independently, but with the support of units such as sea, air, space, and cyber. The army forces need to collaborate more actively and frequently with other forces, firepower, electromagnetic forces, and other forces in the joint combat system through intelligent systems. For example, when the army forces call for drone support, AI can automatically allocate the optimal air resources. The second is that dynamic autonomous collaboration has become the main way. The battlefield situation of future wars is constantly changing, and the combat process is often difficult to advance according to the predetermined battle coordination plan. This requires us to closely monitor the changes in the battlefield situation, implement dynamic autonomous coordination based on data-driven methods, and achieve rapid command and precise coordination of various actions such as power delivery, firepower support, force assault, electromagnetic attack, etc., in order to quickly form an overall synergy. The third is that action effectiveness becomes the main objective. Collaboration between individuals and individuals is not only about resolving conflicts, connections, and complementarity between actions, but more importantly, using combat effectiveness as the goal of coordinating various actions and advancing the combat process. We should focus on the development and changes of the battlefield situation, coordinate and control the strength and intensity of actions such as signal fire strikes and three-dimensional assaults based on the degree of achievement of the strike effect, in order to achieve close coordination based on effects.
