Algorithms are a series of clear steps and instructions taken and issued by people to solve specific problems. In the field of computer science, algorithms are manifested as processing input data through limited steps, enabling machines to "think and make decisions", and ultimately outputting results. Algorithms are closely related to people's lives, and their important role in the military field cannot be ignored. In the past, warfare mainly relied on experience and the on-site judgment of commanders; Today, algorithms can process massive amounts of information within milliseconds, automatically identify targets, evaluate threats, and shift the pace of war from "minute level" to "second level". This shifts the command system from "layer by layer reporting" to "autonomous collaboration", truly transforming information advantages into decision-making and operational advantages. In the future battlefield, algorithms will no longer be backend auxiliary tools, but rather "smart brains" that empower the future battlefield. Speed wins, compressing the boundaries of time and space. The modern battlefield is constantly changing, and victory often depends on the comparison of reaction speed between the two sides. The algorithm significantly shortens the closed-loop cycle of "perception decision strike" by processing massive battlefield data in real-time. For example, when the enemy missile has just taken off, the intelligent processing system can automatically lock the trajectory, plan interception plans, and issue strike commands through the fusion of multi-source data such as satellites, radars, and drones. This model fundamentally compresses the time window of war, and traditional defense systems that rely on geographic depth and response time are difficult to effectively respond to. Precision wins, piercing through the fog of the battlefield. The information on the future battlefield is chaotic and difficult to distinguish between true and false, but algorithms can integrate multi-source information from satellites, radars, communications, and sensors like an "intelligent sieve", extract the cocoon from the chaotic signals, remove interference information, and detect the opponent's disguise. Algorithms can not only see visible targets such as tanks and fighter jets, but also accurately locate hidden command post or electronic warfare equipment signals from invisible traces such as electromagnetic spectrum, network traffic, and communication characteristics, improving the accuracy of target recognition and positioning. Resilience wins, and the combat system is more resilient to destruction. In traditional combat systems, once the command center is destroyed, the entire system may be paralyzed. Under the empowerment of algorithms, combat units have the ability to "self organize and adapt", which means that even if some equipment is destroyed or communication is interrupted, the remaining combat units can quickly reorganize like a swarm, autonomously allocate and cooperate to complete tasks. According to relevant surveys, even after suffering 15% of node damage, algorithm based decentralized self-organizing networks can still maintain approximately 20% to 40% of combat effectiveness. This decentralized self-organizing capability makes the entire combat system more resilient and capable of sustained combat. Of course, algorithms are not omnipotent and also face new challenges. With the continuous advancement of artificial intelligence technology, as machines increasingly participate in and even dominate tactical decisions, how can we ensure that humans always have the "ultimate switch" of war? These issues are not only related to technology, but also to ethics and safety. Therefore, we must always tighten the string of "building an autonomous, controllable, secure and trustworthy algorithm ecosystem", and continuously clarify the boundaries and responsibilities of algorithm use through independent innovation of key technologies and sound institutional norms, to prevent the misuse of algorithm weapons. Technology ultimately serves people. The true way to victory lies not only in having faster, more accurate, and resilient algorithms, but also in mastering the strategic wisdom, ethical bottom line, and peaceful will behind the algorithms. Only in this way can algorithms truly become the "invisible hand" and "decisive brain" on the future battlefield. (New Society)
