The sky is getting dark as the dust rolls around. In mid August, a brigade of the 75th group army staged a comprehensive cross day and night combat exercise in the desert desert. After receiving the order to transfer the position, the officers and men of the missile detachment of the brigade quickly organized the withdrawal of the whole equipment, completed the formation of vehicles, and sped to the reserve position. When the troops moved to the foot of a mountain, they suddenly received a notice that "the road ahead was' destroyed '.". Jiang Peifang, commander of the detachment, immediately called the officers and men to study and judge the "enemy's situation": the Gobi terrain is complex, and if you continue to move, it is easy for the vehicle to fall into the sand pit; If we take a detour to the back of the mountain, the distance will be nearly doubled, which may delay the fighters. After intense discussions, Jiang Peifang finally made up his mind to continue to advance into the Gobi, and at the same time to do a good job in avoiding sand pits and emergency rescue plans. "If we want to win the initiative on the battlefield, we must train our officers and men in all time domain combat capabilities." The leader of the brigade said that they focused on the weak links in night combat, concentrated on refining, improved the difficulty and intensity of night training, and tempered the continuous combat ability of officers and men day and night. At night, when the lights were turned off and they were marching on the Gobi desert, staff sergeant Li Junjun dared not take it lightly. At this moment, he carefully drives the leading vehicle to explore the road in front, and prompts the drivers of vehicles behind him about the road conditions and precautions through on-board equipment. A short time later, a special report of "rear tire puncture" came from the radio. Li Junjun immediately turned around and led some officers and men to the rescue. It is difficult to replace the tire in the dark condition. With excellent equipment maintenance technology and tacit cooperation between officers and men, we quickly completed tire replacement and resumed normal marching. The satellite went over the top, "the enemy" reconnoitred and harassed... All the way, the special situation continued. In the boundless darkness, the officers and men responded calmly and arrived at the predetermined combat area on time. Accompanied by the faint starlight, the officers and men quickly occupied the position, and several missile combat vehicles were ready to launch, ready for battle at any time. At midnight, the temperature in the depths of the Gobi drops suddenly. The cold wind outside the window howled, and the officers and men in the car were boiling with blood. Everyone kept a high degree of vigilance in the dark, continued to search and guard, and did not let go of any clues. Suddenly, the "enemy plane" came at a low altitude, and the missile operator Chen Yongtao quickly locked the target. At the command of Jiang Peifang, the missile took off and hit the target accurately.
