On the training ground of a certain ammunition brigade of the Air Force, as soon as the timekeeper's command was given, several soldiers quickly surrounded an ammunition packaging box, holding electric wrenches to loosen the tightly interlocked butterfly nuts on the box one by one. In the tense air, the sound of metal friction is particularly piercing. As the stopwatch flickered, the officers and soldiers quickly removed all the nuts. On the battlefield, every second carries the weight of a thousand tons. If you take one step slower to unseal, your firepower may be delayed by one point. ”First level Sergeant Pan Kechen said, "In the past, ammunition unsealing often relied solely on 'stupid skills' at hand, and the bottleneck of time was difficult to break through." The turning point of the matter came from a high-intensity live fire training support mission. As the task unfolded, figures shuttled through the ammunition storage room, and all tasks such as handling, counting, and unsealing were carried out in an orderly manner. Suddenly, a piercing alarm broke the silence, and urgent instructions came through the walkie talkie: "Battle level has been upgraded, enter combat readiness, and all support teams must be in place immediately!" The originally stable support rhythm was suddenly disrupted, and the atmosphere in the entire warehouse suddenly became tense. At this moment, the pressure instantly focused on the ammunition unsealing process - according to the task requirements, they had to unseal a certain type of ammunition that exceeded the original plan by double within a very short window of time. At the unsealing point, the soldiers gathered around the ammunition box, constantly waving their wrenches, and their gloves were already soaked in sweat. There were repeated urging sounds on the walkie talkie, and their arms were bulging with veins, still unable to keep up with the speed and mounting requirements of the downward movement ahead. Class monitor, this operation is too time-consuming. I really want the wrench to 'fly'. ”The young soldier, a lone soldier, operated while feeling emotional. This casual sentence "carved" into Pan Kechen's mind. He knows better than anyone that time is life on the battlefield, and ensuring efficiency is combat effectiveness. Every second spent may cause a change in the battlefield situation. The unsealing of ammunition may seem simple, but it is likely to become a bottleneck that restricts the efficiency of support and affects the takeoff time of fighter jets. Pan Kechen had a bold idea in his heart: Can we transform the mechanical wrench into a lightweight and convenient electric butterfly wrench? So Pan Kechen took advantage of the security gap and rest time to tackle the problem. On the desk in the corner of the ammunition warehouse, there was a pile of drawings, parts, and disassembled power tools. He repeatedly measured the size of the nuts, calculated the required torque, and carefully designed the adapter interface. At the beginning, I had no experience. ”Pan Kechen picked up an early developed rough interface and showed it to the author: in the first experiment, due to excessive torque, the nut instantly broke; In the second experiment, due to the mismatched speed, the wrench slipped and did not work. During that time, friendly jokes from comrades could often be heard in the warehouse: "Old Pan, this ammunition depot is almost a repair shop!" However, these failures did not shake Pan Kechen's determination, but instead made him more focused. He repeatedly adjusted, tested, and optimized, using a stopwatch to calculate the opening time of ammunition after each fine-tuning, and finally achieved satisfactory results. When the modified electric butterfly wrench was "fresh out of the oven", under the eager gaze of his comrades, the young soldier took a deep breath, aimed the wrench at the nut, and gently turned the switch. The once stubborn butterfly nut suddenly loosened with a buzzing sound, and in just one sixth of the original time, all the nuts were removed! Touching this butterfly shaped wrench, through the cold metal shell, I felt as if I could sense the surging heartbeat of the ammunition support soldiers. This seemingly inconspicuous wrench carries the winning answer they solved with their own hands in the equation of time and war. A metal cabinet filled with "security secrets" in the quality control room of the brigade caught the author's attention, while an unremarkable tin cabinet. The contents collected here are crucial... "First level Sergeant Li Minghao opened the cabinet door and said solemnly. Inside the cabinet door, there was a unique scent of old paper - yellow notebooks detailing the parameter differences, pressure fluctuations, and disposal processes of different batches of ammunition; In the hand drawn ammunition pipeline atlas, the lines are precise and clear, and the key nodes are carefully marked with content such as "This place is prone to dust accumulation" and "This valve needs to be slowly opened"; The pages of various professional books are rolled up, and the blank spaces are filled with annotations of different colors... Every note, every drawing, and every annotation carries the hard work of ammunition support soldiers. It is those days and nights of dedicated research that have forged strong mental abilities for officers and soldiers. They have memorized hundreds of missile technology parameters and thousands of pages of safeguard regulations, and have safely completed ammunition support tasks for over 30 years. This is the third level sergeant Li Jinjin's, which records the rare faults he encountered and their troubleshooting methods. ”Li Minghao took out a notebook with a worn-out cover from the metal cabinet, with ink layers overlapping and almost soaking the paper. Li Jinjin has always been referred to as the 'walking textbook' by his comrades. This soldier still remembers the embarrassment he felt when he first came into contact with missile equipment. Looking at the switches, buttons, and flashing indicator lights on the instrument panel, he was completely confused and didn't know where to start. Theory is the cornerstone of practice. In order to master the principle of ammunition, he worked overtime to "gnaw" on 14 professional textbooks and wrote over 50000 words of study notes; In order to understand the circuit structure, he searched for the specific positions of electronic components and circuit nodes repeatedly according to the regulations, and memorized every point of each circuit; In order to exercise his operational skills, he followed several veteran squad leaders to learn various "tricks" one by one... Through unremitting efforts, Li Jinjin not only familiarized himself with the technical performance of various types of ammunition in the brigade, but even summarized a complete set of troubleshooting and maintenance processes. The operating principles of different types of ammunition have essential differences, which requires us to master the operating procedures proficiently and thoroughly understand the theory. ”Li Jinjin told me that every time he faced a new type of ammunition, he would take out the materials in the metal cabinet and study them for a long time, repeatedly comparing obscure technical explanations with practical experience in his notes until they were thoroughly digested. Books with different handwriting carry the sweat and hard work of him and his comrades, as well as forging the meticulous craftsmanship spirit of ammunition support soldiers. During a contract tactical training, Sergeant Li Minghao was inspecting a certain type of ammunition when he suddenly noticed irregular stripes on the trailing edge of the ammunition's wing. Comrades speculated that it might be a common appearance flaw, but Li Minghao remembered seeing a similar situation in his notes on the tin cabinet, so he immediately went to look it up. After comparative analysis, Li Minghao concluded that these patterns were caused by internal cracking. He quickly reported the situation and then continued to consult relevant information with other quality control technicians, had in-depth discussions with factory technicians, and went to the site to repeatedly check and confirm. In the end, they confirmed that the crack was indeed caused by internal cracking, and the ammunition was also transported back to the manufacturer for inspection. These materials are the practical 'road signs' drawn by ammunition support soldiers with wisdom and sweat, each stroke and page adding weight to ammunition security. ”Li Minghao said with emotion. A card became the "operation guide", and golden sunlight shone on the apron. Several missiles entered in one after another. First level Sergeant Wang Yapeng held a knife and screws in his hand, and was racing against time to load ammunition against the support card. The author noticed that the card is illustrated with text and highlights key points, covering not only the standardized operating procedures and emergency plans for this type of ammunition, but also the troubleshooting steps and disposal methods for common faults. This card has brought great changes to the ammunition support mode. ”Wang Yapeng told me. For ammunition support soldiers, 'evolution' is not just about improving speed and accuracy. With the increasing number of types of ammunition and the significant increase in difficulty of support, how to ensure the timely release of ammunition while eliminating safety hazards has become a new issue facing them. In practical conditions with multiple models, fast pace, and complex environments, relying solely on personal experience and verbal instruction makes the homework too difficult. ”Wang Yapeng still remembers a training session where the officers and soldiers of the brigade had to provide multiple different types of ammunition to multiple stationed training units at the same time. The number of models involved in the task and the complexity of the process were unprecedented. That time, Wang Yapeng led everyone to unseal and test a certain type of ammunition. Due to limited exposure to this type of ammunition and relatively unfamiliar procedures, he directed while flipping through the key points of the technical manual. Young soldier He Peng nervously followed the instructions step by step. At this moment, another point suddenly called out, "Captain Wang, there is something abnormal with the ammunition detection data. Come and take a look!" Wang Yapeng hurriedly went to deal with it, and before leaving, he reminded He Peng, "Follow my instructions and wait for me to come back." However, due to the noisy scene, He Peng did not hear the specific details explained by Wang Yapeng. Looking at the complex equipment in front of him, he turned on the fan without much thought and directly turned on the device switch. With just a 'sizzle' sound, the sound of a short circuit in the current instantly rang out. Stop it quickly! ”Wang Yapeng, who had just returned, felt a sense of unease and immediately cut off the power supply. Although the short circuit did not cause serious consequences due to timely handling, the entire security process was forced to be interrupted. This accident hit the hearts of the officers and soldiers of the brigade like a heavy hammer. Faced with the complex and ever-changing future battlefield, the guarantee model relying on personal experience appears fragile and limited. After a system review, the team quickly established a research and development team to refine complex support experience into precise "operational guidelines". From unsealing and assembly, appearance inspection, performance testing, storage and storage, ammunition delivery, to safety taboos and emergency response plans... they break down and crush each link, repeatedly scrutinize, verify and simplify, sort out the support process for different ammunition, and make them into support cards. These cards effectively help us standardize our operations. ”Wang Yapeng introduced that it breaks down complex skill requirements into standard movements that can be quickly mastered, which not only helps to ensure more stable and safe ammunition, but also promotes talent incubation in the brigade. Shortly after the release of the card, the brigade was equipped with a new type of ammunition. The operation interface of this type of ammunition is complex and the initialization process is cumbersome, but with the help of the support card, young soldier Chen Chunliang, as the main operator, successfully completed the ammunition performance test. The application of security cards not only promotes a new leap forward in the "all missile" security mode, but also provides convenience for the brigade to accelerate the cultivation of versatile talents. In the past, during peak periods of security, insufficient manpower was the norm. Nowadays, military technicians can also perform basic inspections, and quality control technicians can operate special vehicles. Everyone can handle critical moments! ”Captain Huang Shuai was deeply moved by the new landscape on the battlefield. The tide of the times is surging forward, and the "charge" of this group of ammunition support soldiers is still continuing. (New Society)
