In one year, over 4000 kilometers, two numbers intersect to form the annual journey of a long-range box type rocket artillery vehicle. This is not only a geographical span, but also an extension of the capability radius. Always on the road. ”The artillery commander and second class sergeant of a certain vehicle in the "Model Rocket Artillery Company" of a certain army brigade summarized the year of this tank with this sentence. Standing in front of the chariot, Li hurriedly's chest was filled with indescribable pride. At this moment, the tank is quietly lurking in the yard, with the odometer reading frozen at "4396 kilometers". During this journey, Li Chao recorded three special mileage and destinations - the southeast coast, Chang'an Avenue, and the northwest Gobi Desert. They are like three prominent footnotes, marking the key nodes for the iteration and upgrading of the capabilities of this vehicle group. Mileage: 736 kilometers, shining the sword along the southeast coast, exploring the new "blue ocean" of future battlefield depth. To this day, when it comes to the "Strait Thunder-2025A" mission, Li Chao still remembers it vividly. At the beginning of spring this year, in a certain location along the southeast coast, the atmosphere inside this remote box rocket launcher was solemn. The process goes by every day, but when it comes to live ammunition and simulated shooting, the feeling is vastly different, "Li Xiao recalled. At that moment, the pressure he felt far exceeded the physical sense of recoil, which was a direct test of his actual combat ability. This task requires strict exam questions: the target points must be hit in sequence. This is not only to destroy the target, but also to test the actual combat ability of 'hit where you point'. The initial simulation training did not yield satisfactory results, as the firepower was able to cover the area but the effect of attacking in sequence was not apparent. We must study it thoroughly! "The platoon leader's words fell to the ground. Late at night, the lights of this tank and the command vehicle were still on. The blue light on the screen reflects tense faces, repeatedly modifying plans, adjusting parameters, simulating comparisons... Data rushes in and out like a tide. At that time, it was like solving a difficult math problem. ”Second level Sergeant Xi Yuan, who participated in the research and development, said. From midnight to dawn, after more than 30 rounds of testing and comparison, the new simulation results finally showed success. At this moment, a white fish belly appeared on the horizon. That's the dawn of finding the answer, "Xi Yuan said. Clausewitz wrote in "On War": "War is a field full of contingency." True tests often come unexpectedly. On the last night before the war, this tank, which had been identified as the main gun, was about to complete its final inspection when a drop of rain suddenly fell on Licheng's face. Rain! ”Li Xiao's heart trembled. Without a moment's hesitation, he immediately rushed towards the tank with two operators dragging heavy rainproof cloth. The rain on the beach came as soon as it came, and in the blink of an eye, the wind helped the rain. The rain cloth was pulled up in the strong wind and made a whistling sound. Just as it covered the rear of the car, the front of the car was blown away. In a moment of desperation, Li hurriedly shouted, "Hold it down!" The three of them immediately turned over and threw their bodies onto the several meter long cold cannon barrel, firmly pressing down on the rainproof cloth. The rainstorm poured down on them, and they were all wet, but the gun barrels under them were safe. In the final process drill before launch, Li hurriedly reported to the various elements, and the command post replied: "The gauge error is 0.3." "0.3", this number is within the allowable error range, but it caused the air inside the car to freeze instantly. No, 0.3 is also an error, even a difference of 0.1 is not acceptable! "Li's voice was resolute. All input items such as ammunition type, medicine temperature, and coordinates have been repeatedly verified and are all correct. Where is the problem hidden? Li hurriedly led the crew to start a meticulous investigation. Time passes, and the pressure is like a mountain. In the end, the crux of the matter was locked in an easily overlooked detail: the automatic update of the navigation system. Switch to manually inputting fixed coordinates! ”Instructions are issued. When the corrected variables were reported again, the message of "zero error" finally came from the radio station. That moment finally arrived. The earth trembled slightly, and the rockets thrust into the sky one after another. The images and data transmitted from afar condensed all hardships into good news: the first accurate hit. Subsequently, all rockets exploded in sequence. This mission is a shining example of tackling new tactical tactics, but it is not the only one. In this company, innovative gameplay has become the norm. They continue to carry out the "Golden Ideas for Defeating the Enemy" activity, and the list of achievements continues to expand: 11 tactics have moved from seminars to training grounds, and 6 types of equipment have been innovated, making the "combination of people and equipment" more smooth. Every improvement makes this' sword 'sharper and constantly upgrades the thinking of the' sword bearer '. During a platform confrontation exercise, the rules suddenly changed: 'There is no set launch time, only the moment of explosion is specified.' This is equivalent to eliminating the routine 'timetable'. How to make the entire company work together like a cannon, with different target distances, flight times for different types of ammunition, and preparation speeds for different vehicles? The officers and soldiers of the company quickly sparked a "brainstorming session". When positive thinking hits a wall, they go in the opposite direction. They created the 'time reversal method' - deducing the 'departure time' and 'launch time' of each vehicle from a unified 'explosion moment'. During those two days, the gunners repeatedly memorized the ballistic timetable for different firing distances and conducted countless collaborative exercises. On the day of the assessment, all rockets were fired at different times and covered the target area at the same moment. From tackling major tasks to upgrading training rules, the 'blue ocean depth' that symbolizes the complexity and unknowns of the future battlefield has been surveyed time and time again. Here, this tank and its crew have undergone profound evolution: from passive adaptation to the examination room to actively defining the battlefield; From pursuing firepower coverage to controlling the rhythm of the battlefield. Mileage: 2103 kilometers. Chang'an Avenue was visited, and the ability to engage in combat within a system was felt. When driving a tank and passing through Tiananmen Square for inspection, besides excitement, what else could one feel? On September 3, 2025, at the military parade commemorating the 80th anniversary of the victory of the Chinese People's War of Resistance Against Japanese Aggression and the World Anti Fascist War, the driver of the company, Sergeant Liu Yang, drove this rocket launcher through Tiananmen Square. At that moment, the passion in his chest surged with the torrent of steel. When the entire phalanx moves forward at the same pace, what we feel is a pulsation of the system. ”Liu Yang described his feelings during the parade as follows: the training on the parade ground gave him a new understanding of precise positioning - it's not just about controlling the speed and distance, but about "making the right movements at the right time and place". This experience began on an evening when I first entered the military parade training ground. After the training that day, Liu Yang walked alone to the equipment parking area. In the twilight, cutting-edge equipment from various branches of the military forms silently in formation. In the past, he was proud of the rocket artillery vehicle he controlled. But in front of the steel phalanx that integrated various military forces, a clearer picture appeared before him: on the modern battlefield, there are no isolated "trump cards", only interlocking "system chains". His chariot is a crucial component that must be activated on time and without any deviation. This realization also echoes in the honor room of the company. There, there are two photos taken 70 years apart: one is from 1953, depicting the battle hero Jiao Yuxi. On the battlefield of the Korean War, he bravely led away enemy planes to cover the "Katyusha" rocket artillery position and used his life to protect the entire company's "firing" fighter jets. The other one is a letter of invitation from Second Class Sergeant Chen Hongxing in 2023, with iron handwriting that reads: "I will never be ashamed of my country." Today, this letter has been collected by the Military Museum. What Jiao Yuxi's predecessors guarded with their lives was the fighter jet that the artillery could 'shoot out' on time; What Chen Hongxing wrote down is the determination to 'withstand' the new equipment. ”Captain Li of the company often mentioned during training, 'What we need to ensure is that our equipment will never fall behind in the joint system.' After the parade, Liu Yang's understanding of 'positioning' became more specific. A routine ammunition loading training left a vivid memory in Liu Yang's mind. According to the training outline, the loading vehicle and the launching vehicle need to maintain a "safe distance" to complete the task, and in the past, everyone used to park based on experience. But Liu Yang always had in his heart the feeling of being "perfectly accurate" on the parade ground. In the future battlefield, if we can load faster every time, our firepower vacuum period will be shorter, and the combat rhythm of the entire firepower system will be greatly different. ”He proposed this idea at the review meeting, 'This amount of time may determine who has the initiative to control the next wave of firepower.' Thus, an experiment on 'parking distance' began. On the training ground, Liu Yang and his comrades held tape measures and walkie talkies to repeatedly test the effect of different parking distances on loading speed. A tape measure of 1.5 meters, 1.4 meters, 1.3 meters... precisely measures the distance, a stopwatch records the shortest time, and data accumulates through repeated verification. After dozens of tests, the pattern gradually emerged, and the loading operation action chain was seamless without any delay. The average single homework time has been shortened by nearly 10 seconds compared to the outline standard. For Liu Yang and his comrades, what has been integrated into this journey is the concept of a tank's leap from "firepower coverage" to "system breaking", and it is also the capability coordinate of a modern firepower node in the system picture on the future joint battlefield. Mileage: 3835 kilometers in the northwest Gobi Desert, what is the most important thing for long-range rocket artillery in the era of accelerating combat effectiveness? Time. ”The gunner Li hurriedly replied without hesitation, 'From confirming the target to the shell landing, every second counts down to victory.' This answer had already been engraved in Li's heart when the company first entered the northwest Gobi Desert. That year, within less than a hundred days of installing new equipment, the entire company completed its first test launch in the midst of sandstorms. Many nights, the lights in the wooden houses shone until dawn, and they repeatedly calculated and verified that they had no time to look up at the magnificent Milky Way in the Gobi Desert. When the test mission is successfully completed, they verify not only the equipment performance, but also the "initial speed" of capability generation. At different times, in the same desert, the acceleration of this tank's upgrade is recorded. This year, when the tank once again ran over familiar gravel, it faced a brand new exam paper. The answer is no longer about whether it can be launched, but whether it can be launched quickly and accurately under the extreme conditions of approaching actual combat. One of the tasks in this training camp is the trial and demonstration of a new system. Faced with a completely new system with blank underlying data, security boundaries, and training modes, the company cadres responsible for the task take the lead in overcoming difficulties. During that time, they shuttled back and forth between the tank and the technical room, flipping through materials piled up nearly 1 meter high. Sweat ultimately condensed into a set of key data: from capturing the target to the rocket leaving the chamber, the firepower response time was shortened by two-thirds. In the modern battlefield where every second counts, this time difference often means the difference between active and passive. The refining on the Gobi Desert is not only about verifying abilities, but also about discovering problems. In live fire shooting missions, the tank performed excellently. But at the review meeting, a problem was put on the table: due to equipment design limitations, it still takes too long to load a certain type of ammunition into the entire vehicle. Our 'punches' are already fast, but the interval between' stopping punches and hitting them again 'is long.' It's difficult to make qualitative breakthroughs by practicing with the original methods'... At the review meeting, discussions were constantly taking place. But the generation of combat power waits for no one, and the combat readiness situation waits for no one. During the discussion,
