Keep up the momentum, we'll be at the mountaintop soon! "Sun Changyou, a radar technician from a certain unit of the Northern Theater Command Air Force, encouraged his teammates through the mountain wind in a calm voice. He tightened his tight fitting toolbox harness and steadily climbed the last steep stone step towards the radar station. Just the night before, Sun Changyou had just completed an emergency rescue mission. Without enough rest, he embarked on the next leg of his journey. When Sun Changyou hurriedly arrived at a radar station with a heavy toolbox on his back, it was already past 9 pm. The station leader saw him covered in dust and urged him to rest first. Faults don't wait for anyone, repairing them a minute earlier will give you more peace of mind, "Sun Changyou waved his hand and walked straight into the radar shelter. Troubleshooting, the radar re emitted a stable beam, and outside the window was already a faint morning light. Sun Changyou rubbed his bloodshot eyes and checked the data again to see if it was normal before going back to rest. As a radar technician with 25 years of rich experience, Sun Changyou has long been accustomed to such experiences. High mountain islands, Gobi borderlands, and hundreds of thousands of kilometers of patrol roads measure his persistent footsteps in guarding the "thousand mile eye" of his motherland. In Sun Changyou's heart, safeguarding every radar is to protect combat effectiveness. During a drill shortly after Sun Changyou became a radar technician, a critical radar suddenly went blind. In an instant, there was a blind spot in the command chain, and the air situation was suddenly interrupted. The urgency of the situation and the eagerness of the officers and soldiers made Sun Changyou deeply realize that guarding radar equipment is a race against time, winning the initiative for victory. He and his comrades, under immense pressure, conducted emergency investigations and coordinated repairs, and quickly restored the radar's function, successfully ensuring the successful completion of the training mission. A strong sense of urgency and responsibility drives Sun Changyou to challenge his limits time and time again. During a maintenance mission, the radar beam was abnormal and the fault point was located at the horn mouth of the high tower. The platform is narrow, with strong winds howling from high altitude, and the horn mouth is on the outer edge of the platform, which is very dangerous. Without any hesitation, Sun Changyou and his teammates fastened their seat belts, overcame the enormous pressure brought by strong winds, and almost completed the component replacement in mid air. Radar is like a 'thousand mile eye', we must not let our eyes be covered in dust! "Sun Changyou is not only a skilled maintenance expert, but also an experienced 'gold medal instructor'. After troubleshooting, Sun Changyou often opens classes on-site. Beside the newly repaired equipment, he demonstrated and explained, "Look, the power must be cut off here, and the buckle needs to be lightly pried like this. This abnormal signal often means..." The young officers and soldiers gathered around him and listened attentively. Now, the "Compilation of Common Radar Malfunctions" compiled by Sun Changyou and his team has been updated to the 7th edition and has become a practical textbook for the technical backbone of the unit. Teaching people how to fish is better than teaching them how to fish. ”This is a profound realization that Sun Changyou has gained over the years to ensure his livelihood. "By helping the front line with strong self-learning capabilities, we can seize every second of the decisive battle in times of war." As the mountain wind swept by, the patrol road continued to extend. Sun Changyou carefully counted the tools and turned his gaze to the next coordinate point on the map. His figure merged with the patrol road under his feet, becoming the solid rivet on the chain of victory. Many people think that maintenance is a behind the scenes job, but looking at it from a different perspective, isn't this also the front line? ”When asked about his feelings during the patrol, Sun Changyou pointed to the blue sky and said, "Every time the antenna rotates, the sky map of our country becomes clearer - guarding the peace of this sky is our responsibility and mission
