The northwest plateau is cold and steep in spring. A practical training session was launched in a certain regiment of the Xinjiang Military Region. On site, a new type of missile equipment suddenly malfunctioned. At this moment, Sergeant Li Hongyan, the second level sergeant of the regiment, rushed to the scene to inspect the malfunction and debug the equipment parameters. "Ready to launch!" Li Hongyan signaled to the commander that the debugging was completed. The missile launcher held its breath and pressed the button. With a loud bang, the missile rushed into the sky and hit its target. "Target destroyed!" The news came, and Li Hongyan furrowed his brows and gradually relaxed. As a maintenance technician for a missile system in a certain regiment of the Xinjiang Military Region, Li Hongyan always manages to overcome the "difficult and complicated problems" that arise with various types of missile equipment in the regiment. That year, a new type of missile equipment was installed in the regiment. Not long after, the missile equipment of this type was sent to the field for live fire training. On the eve of training, the missile equipment of this type malfunctioned and urgently needed repair. "Let me give it a try!" At the critical moment, Li Hongyan stepped forward and quickly and accurately identified the fault point, rushing to eliminate all the faults before training. In the 23 years since joining the military, Li Hongyan has undergone multiple iterations of missile equipment updates, from analog circuits to digital circuits, from diodes to chips, from basic maintenance skills to mastery of programming languages... The new missile equipment requires increasingly high professional skills from Li Hongyan. With hard work, dedication to learning and progress, he has caught up with the speed of missile equipment updates and has grown into a "military expert" in the eyes of officers and soldiers. "The report of the 20th National Congress of the Communist Party of China emphasizes accelerating the transformation of technology into combat effectiveness. In fact, if technology cannot be transformed into combat effectiveness, there is no way to win." Li Hongyan sighed, "In recent years, the technological content of weapons and equipment installed in the military has been increasing, and the requirements for personnel quality have also been higher.". I truly feel that innovation is a long and arduous task, and we strive to improve the contribution rate of technological innovation to the growth of combat effectiveness. Grassroots officers and soldiers have made great achievements in technological breakthroughs Some people say that the teacher Fu, who has been dealing with equipment for many years, has a kind of determination to catch up with the next generation of equipment. 43 year old Li Hongyan speaks without hesitation or urgency. When he talks about things that others think are worth showing off for a lifetime, his pace is neither too fast nor too slow. However, when faced with unexpected tasks, Li Hongyan's personality was like a missile in his hand, ready to burst into flames with enthusiasm at any time. This veteran with 23 years of military experience walks at lightning speed. After experiencing multiple missile equipment updates and iterations in the unit, his biggest fear is being left too far behind by the surging era. Comrades describe Li Hongyan as a "trendsetter" who keeps up with the times. In Li Hongyan's view, he is more like being pushed forward by the times, and only by accelerating his running can he catch up with the tide of development of the times. One year, the regiment was equipped with new missile equipment, and this self-taught "military expert" gained more skills and knowledge gaps. He felt as if there was an insurmountable gap between himself and the new weapon. Fortunately, Li Hongyan caught up and once again "tamed" the new missile equipment. His vigorous leap across the divide also proves the confidence and confidence of grassroots officers and soldiers who are not afraid of challenges and strive for progress. A certain regiment of the Xinjiang Military Region organized live fire training, and missiles roared out towards the target
