The world of Jin Lei, a second-class sergeant and sniper in a certain naval unit, is now compressed into a "three-point line" - the violently undulating bow, the calm gaze like water, and the target on the distant wave crest. This is the most challenging bone in the amphibious sniper training organized by the department - the water shooting course. 400 meters away, an orange floating target appears and disappears as the waves rise and fall. The small boat bounced between the waves and valleys, and the crosshairs in the sight shook violently. On an extremely unstable platform, the challenge of finding and utilizing fleeting stable windows is imaginable. Most of the snipers who came forward failed to hit. It was Jin Lei's turn to take the stage, and he did not resist the shaking. Instead, he squatted halfway on the boat, with his knees slightly bent and extended according to the rhythm of the boat. His gaze passed through the high-powered sniper rifle, capturing the irregular trajectory traced by the target in his field of view. At the same time, Jin Lei's brain was rapidly processing a set of data - the content he had become familiar with as a drone pilot: the period of waves, the frequency of the boat's shaking... here it comes! The small boat suddenly jumped onto a wave peak, and at the moment it reached its highest point, there was an almost imperceptible brief pause. Hold your breath, pre press, and fire. Bang! ”After the gunshot, the distant waves splashed slightly. The onshore observation post quickly confirmed: hit the bullseye! A low burst of applause immediately erupted from the observation post. The head coach held a telescope and said to the people around him, 'This shot has meaning!' This shot came from Jin Lei. After ten years of military service, this former communication soldier has grown into a skilled drone pilot and sniper with the unique path of cross-border integration, utilizing "algorithms" to achieve victory. The awakening of a communication soldier - from the "battlefield nerve" to the "central node". Perhaps you cannot imagine, Jin Lei's first "gun" was a field radio that could only make ticking sounds. In early spring of 2016, with his dream of becoming a special forces soldier, he was assigned to a communication unit of a certain navy unit as a new recruit. Late at night, everything was silent. The machine fans in the duty room buzzed softly, and the headphones were filled with electric current sounds. The mission of a communication soldier is to capture specific rhythmic "beep" signals from the ocean of electronic noise. In order to distinguish weak signals, Jin Lei and his comrades often sit for hours wearing headphones, and their necks become stiff after each shift. The two words "communication" on the right arm of the camouflage suit made Jin Lei feel a bit far away from the battlefield of real weapons. Over time, he inevitably felt a little disappointed. During a business exchange, class monitor Li Qing told Jin Lei, "Don't underestimate this' ticking 'sound. If the front line cannot call for firepower and the command cannot be given, guns and artillery will become mere decorations. Our communication soldiers are the nerves of the battlefield. Even if our nerves are broken, our strong bodies will be paralyzed." This sentence fell into Jin Lei's heart like a seed. Gradually, he no longer found the "ticking" sound dull, but instead became obsessed with conversing with these "invisible comrades". Hu Yujian and Jin Lei, comrades in the same dormitory, were soldiers of the same year. In his memory, Jin Lei usually didn't take a break after work, but instead held a thick radio manual and compared each component to the buttons on the machine, muttering words in his mouth. During summer field training, Jin Lei carried a single soldier radio and tested at various points on different terrains, recording signal attenuation. After a trip, his camouflage suit was covered in sweat stains on the back, and I remember it densely packed in my notebook. Jin Lei not only researches on his own, but also enjoys sharing with his comrades. He often puts forward ideas during training breaks: "If the command post is transferred, how can we quickly build a communication hub at a new location? How can existing equipment be combined to ensure minimal communication in a strong electromagnetic interference environment?" During discussions, comrades often argue fiercely, while their problem-solving abilities continue to improve in such "brainstorming" sessions. Later, the brigade organized a communication business competition, and Jin Lei's class became a famous "sharp knife class". This experience has subtly changed Jin Lei: it has worn away the restlessness in his heart, cultivated a rigorous and meticulous habit, and planted a sense of "system" and "link" in his mind. While honing his communication skills, Jin Lei never gave up his dream of becoming a special forces soldier. He diligently practiced courses such as armed off-road, rifle shooting, and individual tactics to hone his abilities. In his study notes, Jin Lei wrote the following sentence: "We cannot just be a 'mailman' transmitting signals. We must strive to become a central node of battlefield information that can understand, judge, and handle." The evolution of a drone pilot - connecting the "Eye of the Sky" and the "Eye of the Earth". In the summer of 2021, Jin Lei returned from military school and came to the reconnaissance camp as he wished. Through diligent training, he gradually mastered more than 20 special combat skills such as climbing, parachuting, boating, parachuting, and fighting. Soon, Jin Lei eagerly awaited an opportunity - the reconnaissance camp began selecting snipers. He submitted his application with great anticipation. Unexpectedly, his superiors recognized his solid communication background and excellent system learning ability, and assigned him to the drone reconnaissance class. On the day of registration, looking at the various shapes of drones in the warehouse, Jin Lei felt a little uneasy. The transformation occurred after he independently controlled the drone to take off for the first time - the screen began to rise from the lawn of the camp, and the field of view became increasingly broad. When the drone flies over a tactical training ground, the real-time images transmitted back clearly display the location of the "enemy" simulated fortifications, the movement trajectory of personnel, and the model of vehicles. An unprecedented sense of global control rushed towards me. It's like... suddenly opening up a god's perspective for you, "Jin Lei was deeply shocked." Before, on the ground, you could see tens or hundreds of meters in front of you; now, with drones, you can see the terrain and military deployment several kilometers away. "Jin Lei keenly realized that modern sniping is not only a competition in optical lenses, but also a game of multidimensional perception systems. There is a close connection between the "Eye of the Sky" of drones and the "Eye of the Earth" of sniper scopes. During the day, he is a drone pilot, and his training includes route planning, target recognition, positioning calibration, and meteorological monitoring; In the evening, he applied to train with the sniper team to see how they choose positions, calculate distances, and correct wind deviations. In daily practice, Jin Lei began to consciously combine drone operations with sniper training. When operating a drone, he will consider which areas are ideal sniper positions; When observing sniper training, an aerial view of the corresponding area will automatically appear in his mind, calculating the optimal monitoring angle after the target moves. Once, the reconnaissance camp organized a red blue confrontation training, and Jin Lei was responsible for cooperating with a sniper team in the operation. At that time, a key firepower point of the 'Blue Army' was hidden on the reverse slope, and snipers could not directly observe it. Jin Lei controlled a small unmanned aerial vehicle and used an ultra-low altitude flanking method to quietly approach from the flank, successfully capturing the exposed location of the firepower point and transmitting accurate coordinates and images in real time through a data link. Subsequently, Jin Lei reported through the individual radio station: "Target confirmed, in your 10 o'clock direction... current wind speed in the area is level 2, east wind, suggested correction amount..." A few seconds later, a sniper successfully carried out a "blind spot" sniper based on the parameters provided by Jin Lei. After the drill, during the review, the sniper specifically approached Jin Lei and excitedly said, "Your 'air guide' is so effective! We need to cooperate more when there are tasks in the future." Encouragement from the leader and recognition from his comrades made Jin Lei suddenly realize that his superiors placed him in the position of drone pilot because he had the potential to connect different combat elements. So, Jin Lei began to systematically organize his cross-border training experience, and marked the elevation, slope, vegetation and other information next to the terrain and landform screenshot taken by the drone on the left side of his notes; On the right side, corresponding suggestions for selecting sniper positions and analysis of ballistic influencing factors should be written; In the middle, different colored handwriting is used to record key communication nodes and backup plans. As the notes became thicker and thicker, Jin Lei's confidence in his martial arts and strong abilities also grew stronger. He successively won the first place in the sniper training and the first place in the "reconnaissance elite" competition of the unit. The breakthrough of a sniper sharp soldier - the test of "changing guns on the battlefield" and "adaptability" - the true test always comes at unexpected moments. In the first half of 2025, drone pilot Jin Lei was selected to join the training team to prepare for the "Blake-2025" international sniper shooting competition. During the training period, Jin Lei conducted sniper training for up to 16 hours every day, eating three meals a day at the training ground, and doing his best to win a ticket to represent the Chinese Navy in international competitions. On the day of the final assessment of the training camp, an accident occurred. After checking the accuracy of Jin Lei's sniper rifle, the head coach announced, "The gun is not working." Taking the sniper rifle that had been with him for a long time, Jin Lei's face turned pale, and his fingers slowly touched the barrel, handguard, and stock without saying a word. For snipers, guns are not only weapons, but also a community of life forged through thousands of shooting experiences. Changing guns at the last minute is like a basketball player changing into a pair of new shoes that don't fit before the finals. The comrades who were watching all sweated for Jin Lei. A few minutes later, Jin Lei took a deep breath, gently placed the gun aside, and said to the head coach, "Report, I request to use a spare rifle for immediate shooting." Immediately, Jin Lei walked into the weapons room and retrieved a brand new spare sniper rifle of the same model. Next, he seemed to switch modes. The emotional fluctuations caused by the loss of an 'old buddy' have disappeared, replaced by an almost cold calmness. He returned to the communication soldier who was accustomed to meticulously checking the wiring: according to regulations, he meticulously checked the mechanical zero point of the new gun, the installation baseline of the optical sight, and the status of all moving parts. He transformed back into the drone pilot skilled in data modeling: loading, loading, aiming, firing, checking the target paper, recording deviations, calculating data, adjusting the sight... 100 meters, 200 meters, 300 meters, constantly repeating the cycle of "shooting inspection correction" at different target positions. At that time, I was right beside Jin Lei. ”Comrade Xia Hongcheng from the training team recalled, "Everyone was worried about him, but he was very calm, with clear thinking and even rhythm. It felt like he was not adapting to the gun, but programming to 'input' his own shooting parameters for this new gun, so that the gun could adapt to him." "The ability to respond to emergencies is also a core quality of snipers. ”Throughout the afternoon, the coach and class monitor were observing every move of Jin Lei. In the end, Jin Lei used his "new partner" who had only been working together for an afternoon to achieve stable results under various complex conditions and successfully selected for the participating national team. In the "Blake-2025" international sniper shooting competition, Jin Lei and his teammate Xia Hongcheng passed the test and stood out from 52 domestic and foreign participating groups, winning the championship of "group all-around" and becoming a true "gun king". A coach's exploration from "skill integration" to "thinking upgrading" has returned with honors, and Jin Lei has been awarded second-class merit. Unfortunately, due to factors such as being over age, he missed the opportunity to be promoted, and some of his comrades felt sorry for him. At a symposium organized by the reconnaissance camp, Jin Lei candidly stated, "There is a finish line for the competition, but there is no finish line for the construction of combat effectiveness. I think the significance of this is to turn the experience I have learned and explored into abilities that more comrades can master, and to enhance the overall combat level of the army
