If the word 'benchmark' is added before the name of the battle position, the meaning of this battle position will be slightly different. After the unification of the six states by Qin, an important national policy was to unify "weights and measures". Some standard instruments were distributed to various counties and districts across the country as "benchmarks" for the government and the public to verify weights and measures. In the Modern Chinese Dictionary, the term 'benchmark' is interpreted as' the starting standard for measurement '. In some earlier literature, "benchmark" represents the reference starting point for measuring dimensions and is used as a reference object to determine the actual direction or positional relationship of associated features. 'Benchmark' means standard and reference. Other people or things use "benchmarks" as coordinates to measure their own direction and position. Zhu Yongsheng, the benchmark artillery commander of a certain brigade of the 82nd Group Army, and his comrades may have enough experience to explain the meaning behind the word "benchmark". As the middle gun of the artillery position, the reference gun is the first shell fired during each training exercise. The test firing of the reference gun has been completed, and other guns have calibrated their firing direction based on the judgment of the reference gun, completing the shooting. The group of soldiers responsible for firing the baseline gun is the baseline gun commander. A benchmark gunner not only needs to be proficient in artillery professional skills such as element calculation, password transmission, artillery inspection, and firing operation, but also needs to help other artillery on the artillery position calibrate the firing accuracy and control the firing rhythm of the artillery. The speed at which the first shell of the benchmark gun is fired directly affects the fire response speed of the entire squad. ”Zhu Yongsheng and his comrades often feel that behind the "benchmark" lies a heavy responsibility. In these years, during their time as the "benchmark", they have gained a deeper understanding of the position they have defended, and often feel that their personalities have been reshaped and changed due to their identity as the "benchmark gunner". In the dictionary of the benchmark gunner, there is no "almost" between mountains and fields. A practical artillery live fire training has begun. Aim carefully, prepare, release! ”After receiving the command from the command post, the base gunner Song Shengjian quickly issued the command order and fired at the target position first. In an instant, with a deafening roar, flames erupted from the muzzle of the reference cannon, and shells roared out like lightning. Hit the target. ”A few tens of seconds later, the command post transmitted the coordinates of the benchmark cannon explosion point, and all other artillery vehicles in the artillery position fired shells in unison. In an instant, the "enemy" target was suppressed. In just a few tens of seconds, Song Shengjian received and recorded the operating conditions while staring at the various elements of the fire control computer, completing a series of operations such as calculation, correction, and execution. His fingers danced on the control panel, and a series of movements were performed in one go. Ensuring the rapid and accurate completion of operational instructions in a short period of time, enabling the projectile to accurately land in the target area, is the main task of the reference gunner. On the artillery position, the reference gun is the "signal gun" of the artillery unit, and other artillery pieces need to quickly adjust parameters based on the landing point of the reference shell. The shooting window is fleeting, and if the baseline gun's firepower response is slow or wrong, it will delay the firing rhythm of the entire artillery unit, resulting in missing fighter jets. Zhu Yongsheng, the benchmark artillery commander, likened the importance of this position to "the foundation of a building". "If the foundation is crooked, the building will definitely collapse, and every action of the benchmark artillery commander must be a reference standard for everyone". As a reference for others, one should become a ruler with a precise scale. In order to accurately grasp the feeling of "not being too bad", Zhu Yongsheng often stared at the precision scale of the artillery sight and practiced the "feel" of fine-tuning accuracy. The circle of the artillery sight is 360 degrees, which is equal to 6000 density positions, and 1 density position is equal to 0.06 degrees. During Zhu Yongsheng's practice, he only rotates 1 level at a time, seeking a tactile sensation of 0.06 degrees. After practicing for a long time, a layer of fine calluses has been worn on the fingers that rotate the sight and screw. I rotated thousands of times a day, and there was a groove in the middle of the cocoon. Now, even with my eyes closed, I can tell how many degrees I rotated, "he said. The "feel" is accurate, and the "calculation" is even more accurate. Benchmark gunner Yi Yang has been sensitive to numbers since childhood, enjoys mathematics, and excels in calculations. However, when he first encountered this position, the complex calculations of various elements still posed a challenge for him. Zhuyuan Calculation is a training course designed to improve the manual shooting accuracy of artillery operators. During training, artillery gunners need to accurately calculate the various technical parameters required for artillery firing. These parameters directly determine the aiming direction, firing angle, and charge number of the artillery, and are the key to ensuring the accuracy of artillery firing. Yi Yang repeatedly pondered and verified until he became familiar with various parameters. Data input "is a fundamental exercise in the subject of arithmetic. In order to improve data input speed, Song Shengjian carried a load on his wrist and changed his habit of inputting data with two fingers, practicing input operations with five fingers together. The buttons on the computer were very hard, and Song Shengjian's fingers quickly ground blood bubbles. He picked up the blood bubbles and continued practicing, grinding new blood bubbles on his fingers... After picking and picking, he finally improved his score by 40 seconds. This pursuit of excellence will also blend into the character of the benchmark gunner. After becoming the benchmark gunner, Song Shengjian felt like he had become a "detail controller". On a festival, the unit organized the making of dumplings, and each dumpling he made had even kneading force, even the number of folds was the same. Another time when loading artillery ammunition, he lowered his head and instinctively checked the production batch of ammunition. The initial velocity of ammunition from different batches may have deviations, and if the details are a little worse, the landing point on the target area will be one piece worse, "he said." In the dictionary of the benchmark gunner, there is no 'almost'. "The solid operational skills of the benchmark gunner have saved them time to react quickly on the battlefield. On the day of live fire shooting, after the benchmark gun whistled out of the chamber, Yi Yang stared at the shooting parameters calculated by the fire control panel, anxiously waiting for the radio to broadcast the shooting results... In just over 30 seconds, he had pre-set many possible scenarios in his mind. Soon, there was a notification of the "first hit" on the radio. Subsequently, the artillery positions fired in unison, striking the "enemy" targets with precision. At that moment, Yi Yang finally breathed a sigh of relief. By understanding the temperament and thinking of artillery, one can definitely solve problems. Strengthening one's basic skills is only the first step, and a qualified benchmark artillery commander also faces many unexpected tests. Some come from unpredictable weather - it suddenly rains on the day of live fire shooting, but the shooting continues. What should I do? During a training mission, the benchmark gunner Li Ziheng stared closely at the screen and stood in front of the artillery computer, his fingers jumping rapidly on the control panel. Suddenly, there was a sudden change in wind direction and an increase in wind speed, which affected the trajectory of the projectile's flight. Li Ziheng carefully analyzed and immediately recalculated the trajectory, adjusted the parameters, and conveyed the correction instructions to each gun position. After the command was given, the first shell whistled out and landed accurately in the target area, which relieved him greatly. Some cases come from sudden malfunctions of artillery - 'We should think what the artillery thinks'. ”The benchmark gunner Wang Mengfan still vividly remembers an experience two years ago. During the live fire training organized by the superiors, a cannon could not be fired after being loaded with ammunition, and the shell got stuck in the barrel. The gunner Zhang Yuhang was a bit confused and dared not operate it easily. After receiving the notification, Wang Mengfan quickly rushed to the scene, checked the situation of the gun barrel, and determined that the improper loading operation caused the "jamming" of the ammunition, and finally successfully eliminated the fault. There was also a live fire training where after the benchmark gun was fired, the turret power supply was unable to provide power, and the gunner was unable to communicate with their superiors. Yiyang's analysis found that the loose connection of the distribution box cable caused a power outage, but the equipment returned to normal after reconnection. Li Ziheng has also encountered such a situation. Faced with the sudden abnormality of the artillery inertial navigation equipment during shooting, he quickly completed the mechanical aiming and setting action with muscle memory, and the shell finally hit the target area. The trajectory of the shell from firing to landing in the target area is a testament to his rigorous training. There are also some psychological tests - the aiming hand Chen Tao blinked uncontrollably when he was nervous from a young age, which prevented him from forming a line of sight when aiming at the target during live fire shooting, affecting the accuracy of the shooting. In order to help him overcome his nervousness, the benchmark gunner Xie Zhiheng invented the "staring needle technique": he inserted a needle into the wall and stared at it for 10 minutes every day. After 3 months, Chen Tao was able to aim at the target for 30 seconds without blinking. Comrades also designed a "blindfolded shooting" training method for him: wearing an eye mask, comrades observed his training status, corrected erroneous movements, and Chen Tao gradually overcame his fear of shooting. In the complex and ever-changing battlefield environment, the benchmark gunner not only needs to possess superb operational skills, but also accurately analyze the situation, with keen insight and the ability to respond to changing situations, to point out the direction for the entire artillery unit. They reflect on these experiences and integrate them into methods of summarizing and refining them one by one. When Zhu Yongsheng first installed a certain type of howitzer, the speed of operating the fire control system was always half a beat slow. He compiled the operation steps into a 4-step mnemonic of "start set correct fire", trained while holding the simulated operation panel he drew during lunch break, and used his fingers to gesture the panel buttons in bed at night. After a period of time, the operation speed significantly improved. During the training of the benchmark gunner Zhu Mengqi, it was found that the sight of the aiming hand on the vehicle was limited, making it difficult to find the aiming point in the first time. He repeatedly explored and summarized a new method: determining the direction of the aiming point under the car, determining the approximate position of the aiming scope, calibrating the aiming point twice, and finally recording the data. This method shortened the manual operation time of the aiming hand and was quickly promoted... During a lecture, everyone asked Wang Mengfan standing on the podium, "How can artillery commanders improve their ability to handle live fire situations?" "As long as you understand the temperament and thinking of artillery, you can definitely solve the problem..." Wang Mengfan answered with a smile. The smarter the equipment, the more it tests the gunner's true skills. After the installation of the new informationized artillery, the benchmark gunner Zhu Yongsheng felt a significant generational change. This starts with one of his experiences. During a live fire training, a data anomaly occurred in a certain artillery system. Zhu Yongsheng immediately switched to a downgraded manual shooting mode based on his experience. Even though he made quick and accurate judgments in a short period of time, he still missed the best shooting time. In contrast, other gunners use the new gun's fully automatic shooting mode, which allows for faster and more accurate hitting of targets. After this experience, he fell into deep thinking: in the past, gun adjustment was mainly done manually, and the gunner had to be proficient in calculation, command and coordination, and rely on experience to judge and correct. Nowadays, the integrated fire control terminal and "fully automatic gun adjustment" button of information-based artillery equipment can automatically point the gun barrel to the target direction with just one click. Is manual gun adjustment really outdated? Also caught up in contemplation is the benchmark gunner, Song Shengjian. In recent years, the upgrading and replacement of artillery equipment have constantly refreshed his understanding of being a good benchmark gunner. In the summer of 2022, he participated in a live fire shooting competition organized by the group army. Mountain shooting range has complex meteorological conditions. Song Shengjian pressed the auto adjustment button, and the gun barrel buzzed and rotated. The parameters on the terminal screen jumped, and finally came to a stable stop. Everything seems perfect. However, just before preparing to fire the cannon, he habitually rechecked the target area with a periscope, and couldn't help but feel a "thump" in his heart: there was a small but not negligible angle difference between the barrel pointing and the judgment result based on the target's terrain reference! Why is there such a deviation when the automatic gun adjustment system displays that the installation is correct? Time is tight, should we trust the data on the screen or rely on our intuition and experience judgment? No time to hesitate
