Late at night, everything around him fell silent. Between the mountains and the fields, in the computer room of a certain army brigade, everything is still busy. Eyes firmly locked on the screen, nerves constantly tense... This is the daily state of the electronic reconnaissance company officers and soldiers of the brigade. Compared to the bustling and bustling cities, 'loneliness' may be the most appropriate synonym here. Rooted in this, it means they must abandon comfort, stay away from family and friends, and devote themselves wholeheartedly to their work. Day after day, the continuous sound of radio waves in their ears tested their patience and will in every minute. Defending an inch of territory, young officers and soldiers also look towards the distance. Thousands of miles away, there are close relatives, companions who work together with peers, comrades who enlist together... On the path of pursuing dreams, they make agreements and continue to move forward through mutual encouragement. Starlight does not ask passersby, time does not disappoint those who strive. Today, we approach the Three Foot Machine and witness the "Thousand Mile Pact" one by one. The Three Foot Machine witnessed the "Thousand Mile Pact" defending its position, shining brightly as night fell. Corporal Wu Yankun once again looked up at the starry sky. After arriving at the electronic reconnaissance company of a certain army brigade, Wu Yankun inadvertently developed this habit. In spring, summer, autumn, and winter, the stars flicker and change on the deep black sky, just like the "scenery" constantly refreshing on a square inch screen. In September 2019, Wu Yankun joined the military with his younger brother Wu Yikun. Holding a steel gun in hand, the two brothers confidently agreed: "In the military camp, we must do something!" After the new training, Wu Yankun was assigned to the electronic reconnaissance company. Climbing onto the high ground, overlooking the breathtaking sea and mountain scenery, Wu Yankun, who had just arrived in battle, was full of anticipation for the future. However, this enthusiasm did not last long, and the vast signal parameters and complex professional principles gave Wu Yankun a "blow to the head". Wu Yankun's position has a fast pace and high intensity of work, and his mind must always remain clear. The constantly beating interference signals on the screen often make Wu Yankun gasp for breath. At that time, Wu Yankun was a bit envious of his younger brother, who was thousands of miles away. After his younger brother Wu Yikun joined the company, he was assigned to an honorary company and served as a station measurement and control officer. During a performance report meeting, Wu Yankun met his younger brother through a video conferencing system. When the leader presented the honor medal, the camera happened to give a close-up of his younger brother, who smiled so brightly. Is it like being separated by his younger brother like this? "Wu Yankun pondered for a long time and made up his mind to" defend his position and strive to go further. "From then on, Wu Yankun faced the loneliness and boredom of the Three Foot Machine, seized every opportunity on duty, carefully summarized the changing characteristics of various signals, and copied them one by one. Even when not on duty, he "riveted" on the machine and asked experienced veterans for advice. The solitary light at night illuminated Wu Yankun's posture as he lay on his desk and studied, and his thick notebook was filled with his thoughts and insights. Kung Fu pays off to those who care, and Wu Yankun has finally developed his own "unique skill". During a confrontation drill, Wu Yankun detected a deeply hidden "enemy" target and promptly reported it, receiving praise from his superiors. Although there is no gunfire or gunfire, the high mountains and islands are our positions, and the square inch screen is our battlefield
