Inside the armored vehicle yard, Shi Yu is organizing the work notes in the command vehicle's data cabinet. Three large books and over 20000 words, this is a valuable asset he has accumulated over the years in his position as a technician. It is precisely through these accumulations that he gradually grew from a "professional novice" to a "soldier expert" in the eyes of his comrades. In 2019, Shi Yu transferred to become an accused technician. During a training session with the factory, he faced various complex communication equipment and rose to the challenge. This is a great opportunity for me to learn and grow, and I must seize it. "Shi Yu silently made up his mind to drill through the equipment and refine his skills. Shi Yu's habit of organizing notes is what he left behind during that period of time. During the training with the factory, he sometimes encounters multiple manufacturers explaining the operation and use of various types of equipment in one day. Due to his weak foundation, he could only grit his teeth and record all the operating steps explained by the manufacturer first. When he rested at night, he got into the car and familiarized himself with the operation steps by following the diagram, slowly digesting and absorbing them. At that time, he spent more than 10 hours a day researching new equipment, and his professional skills were rapidly improved through solid accumulation. One day, while explaining the functions of a certain software, the coach discovered that Shi Yu was a good candidate and encouraged him, saying, "Having a certain talent means you can quickly get started with new equipment. In the face of daily boring basic training and rapidly updating information systems, you must always maintain the initial enthusiasm and be good at updating your mind. Only in this way can you grow into an excellent command and control technician." With a diligent and studious spirit, Shi Yu gradually grew from an operator to a technical expert in commanding information systems throughout the company. During a higher-level martial arts competition, a piece of equipment lit up a "red light" during the early communication test. In order to find the source of the problem, Shi Yu got into the command vehicle alone, tried different operation methods according to the equipment manual, and finally solved the problem before the competition. In order to prevent similar problems from happening again, Shi Yu actively contacted software and hardware manufacturers afterwards, seeking technical assistance and guidance, and completely eliminated the hidden dangers of the problem. In recent years, Shi Yu has actively led communication technicians from various teams to conduct special summaries on the networking issues of new equipment, sorted out operating procedures, listed common problems and solutions, and taken on the teaching and training tasks of camp networking training, greatly improving the ability to connect camp networks. Diligent study is the necessary path to success Shi Yu said. With this driving force, he has taken on tasks such as equipment research and development upgrades multiple times, improved multiple support modes, and trained a series of skilled command and control personnel for the brigade.
