In the hinterland of central Shandong Province in autumn, a brigade of the 80th Army Group was engaged in a fierce confrontation drill. In the UAV control cabin, Li Jianlin, a first class sergeant and flight controller, skillfully controlled a type of UAV to go forward for reconnaissance and send back the battlefield situation in real time. "President Xi pointed out in the report of the 20th National Congress of the Communist Party of China that the people's army has a new system, new structure, new pattern and new look. As a new quality combat force, our staffing, equipment and elements have been continuously optimized and our combat effectiveness has been gradually improved in the past decade!" Looking back at the sonorous pace of the reform and transformation of the armed forces, Li Jianlin expressed his joy in his heart. As a UAV flight controller, he is determined to translate the political enthusiasm of studying the report of the 20th National Congress of the Communist Party of China into practical action in the next drill, and to fulfill his mission in the process of practical quenching. At the drill site, as a whistle sounded, the officers and soldiers moved to the unfamiliar area quickly. "'Enemy' reconnaissance satellite transit!" In the middle of the road, all kinds of special situations came at once. The reconnaissance team quickly relied on the disguise of the mountain col and sent special troops to launch a concealed infiltration assault on the "enemy" in multiple ways. The battlefield was filled with smoke and the sound of keyboards in the shelter. Li Jianlin, who was engaged in battlefield reconnaissance, stared at the screen and steadily controlled the UAV to move forward, sending information back to the command center continuously. The special operations team members who received the instructions took the assault vehicle and quickly arrived at the position to complete the search for the remaining targets. Five years ago, Li Jianlin was transferred from parachuting to UAV in the tide of reform. In the face of new equipment and unfamiliar majors, Li Jianlin, relying on his willingness to study, rapidly improved his abilities and was appointed as a UAV technician and monitor. During the training, Li Jianlin talked about the national defense and military building in the report of the 20th National Congress of the Communist Party of China (CPC) at the "Battlefield Lecture Hall" organized by the battalion, It resonated with the officers and soldiers: "President Xi pointed out that only by unswerving and unswerving, can we live up to the times and the people. As soldiers, we should work hard and forge ahead bravely, practice our ability to win in battle positions, and contribute our own strength to achieve the centenary goal of building the army!"
