"Shi" is one of the important concepts in traditional Chinese military science, which refers to an objective state in which one is in an active position in war or strategic games, with a superior situation, stronger force, superior situation, and superior momentum. This objective state plays a crucial supporting role in the planning, communication, warfare, and siege of cities. Being adept at using force was the magic weapon for ancient Chinese military strategists to win. At present, the accelerated evolution of information and intelligent warfare requires a focus on utilizing potential and being adept at using potential in order to firmly occupy the initiative on the battlefield. As stated in Sun Tzu's Art of War, "Those who are capable of using potential should exercise power based on their own interests." "Those who are skilled in warfare should seek potential and not be held accountable to others, so they can choose people and take on the potential.". Shi, as an intangible combat energy, is the key to defeating and defeating the enemy. The ability to form a favorable situation for oneself but not for the enemy is directly related to the success or failure of the battle. Shi exists in the macro world based on the basic element of time. The seemingly intangible "shi" actually has a natural and inseparable connection with "shi". Grasping the dialectical relationship between "shi" and "shi" is conducive to understanding "shi", clarifying "shi", and making good use of "shi". Create momentum with time. Time has absolute fluidity. With the flow of time, the development situation and trend of things will also change. Actively using "time" to create "momentum" is conducive to mastering the initiative in combat. The Four Crossing of Chishui is a model of using "time" to create "momentum". After the failure of the fifth anti encirclement campaign, the Central Red Army was trapped in layers of encirclement by the Nationalist army, objectively at a disadvantage. Comrade Mao Zedong commanded the Central Red Army to shuttle back and forth within the enemy's encirclement, leading the enemy by the nose while creating a favorable "momentum" to break out of the enemy's encirclement, thereby leading the Central Red Army to turn danger into safety. When the overall situation develops in favor of our own side, we should learn to follow the trend, find the right fighter jet, take the initiative to attack, and defeat the enemy with one strike; When the overall situation is developing against one's own side, one should learn to go against the "trend", give play to the subjective initiative of the commander, actively exchange time for space, lead the enemy and adjust the enemy in moving, and seize the limited time window to destroy the enemy while preserving oneself. When tired, accumulate momentum. From the potential energy formula in physics, it can be seen that whether it is the "h" in gravitational potential energy or the "x" in elastic potential energy, these coefficients are directly proportional to time "t", which means that the accumulation of "time" can achieve the function of storing "potential". Combat is nothing more than this. A fully prepared army often has more momentum, because whether it is manpower, financial resources, material resources, or weapon and equipment production capacity, they are all proportional to time. By leveraging the accumulation of time, more momentum can be achieved. The "Ten Major Military Principles" state that "in each battle, concentrate absolute superior forces (twice, three times, four times, sometimes even five or six times the enemy's forces), surround the enemy on all sides, strive for complete annihilation, and avoid looping through the net." By continuously maneuvering and concentrating one's own "momentum", continuously adjusting and dispersing the enemy's "momentum", and utilizing the cumulative effect of time to complete a process of accumulating "momentum", and thus forming an advantage over the enemy. This is not in conflict with current concepts such as "distributed warfare". "Distributed warfare" aims to maximize the energy of dispersed deployed forces and firepower through advanced network information systems, and its key lies in pre war accumulation. Control the situation with time. Time not only has fluidity, but also directionality, that is, it flows forward, like a process of opening a canal to divert water, which provides us with a relative flow direction for controlling the development direction and degree of momentum. Controlling the "momentum" in combat also requires the use of the "time" factor, which reflects the art of command in terms of when to release, how to release, and when to collect. The combat method of "eating one, sandwiched one, and watching one" in the Huaihai Campaign well reflects the characteristic of "controlling the situation" with "time". In the situation where our army's overall strength is not superior, to achieve the "three stages" of enemy annihilation goals defined by the Central Military Commission, it is necessary to exert the most advantageous ability of only the "momentum" of the military force. In each stage, a combat target is determined, and various combat methods such as encirclement and support, encirclement but not annihilation are adopted to break through each one by one. In the first stage, we will eat Huang Baitao, sandwiched Huang Wei, and watched Du Yuming, and in the second stage, we will eat Huang Wei, sandwiched Du Yuming, and watched Li Yannian. In the third stage, eat Du Yuming. By accurately grasping the "time" and "momentum", and based on limited military "momentum", the precise release of "momentum" is controlled by the reasonable use of "time", thereby achieving victory with less. Identify the time and interpret the situation. The law of energy conversion tells us that, based on the same conversion efficiency, the party that performs the maximum work in a short period of time will obtain greater energy. In other words, in combat, being able to utilize limited time windows, seize advantageous aircraft, accurately identify enemy system nodes and key links, and instantly release maximum energy, increases the probability of winning the "momentum". This is the winning strategy of modern warfare. Opportunities cannot be missed, time never comes again. On the stage of war, excellent commanders are not only able to use "time" to create "momentum" and control "momentum" with "time", but also able to understand "time" to interpret "momentum" and always have the initiative in combat. In the Battle of Menglianggu, Su Yu accumulated the momentum of combat through extensive maneuvering and enemy mobilization. He keenly grasped the favorable timing of Zhang Lingfu's solitary and aggressive advance, quickly made up his mind to fight, and "fiercely fought" to annihilate the reorganized 74th Division of the Nationalist Army, which was the "top five main forces". In modern warfare, as the enemy's combat deployment becomes more dispersed, there is an increasing need for precise identification of "time" and the implementation of rapid and fierce attacks on key enemy targets in the main direction, main battlefield, main combat stages, and important moments of main combat operations, striving to achieve victory in the first battle. Break the momentum by borrowing time. Although time has absoluteness, it has relativity for two different moving substances, the enemy and us. By utilizing the relativity of time, one can form an advantage over the enemy, which is also the reason why "troops are precious and fast". By maneuvering faster than the enemy, one can create a "time difference" and thus achieve an advantage over the enemy. In the Battle of Pingjin, while Fu Zuoyi was indecisive, the Central Military Commission ordered the Northeast Field Army to suspend rest and secretly quickly enter the border. Using Fu Zuoyi's illusion of judging the war situation, a "time difference" was created, instantly shifting from a disadvantage to an advantage in military strength comparison, and from a defensive position to an offensive position on the battlefield, ultimately laying the foundation for the victory in the North China battlefield. In the second battle of the Korean War, the 38th Army quickly penetrated 72.5 kilometers in 14 hours to seize Sansuoli in front of the enemy, cut off the enemy's retreat, annihilated a large number of enemy forces, and broke through the enemy's western line layout. In modern warfare, the philosophy of "fighting slowly with speed" is not outdated. It is only a shift from traditional military mobility to a "three in one" approach of information, firepower, and military mobility, and from static decision-making to dynamic and real-time decision-making.
