In early spring, a land air confrontation drill kicked off in an air defense brigade of the 77th Group Army. To the reporter's surprise, the commander of the air defense unit who issued orders at the "Zhongjun tent" was wearing a blue flying suit. According to the introduction of others, the commander's name is Li Bojun, who is an armed helicopter pilot from a land aviation brigade of the group army. Since the beginning of last year, he has joined the Air Defense Brigade as a deputy battalion commander from a pilot position. The fierce battle was raging when suddenly the radar sounded an alarm. On the display screen, multiple target points were constantly flashing, rapidly approaching the anti-aircraft camp position. Li Bojun, who was staring closely at the screen, assessed the "enemy situation" from the trajectory and posture of the target and ordered the air defense team to adopt targeted tactics to resist. Radar tracking, silent commands, everyone is constantly monitoring the progress of the battle. Not long ago, in the air defense position, the missile dragged its tail flame straight into the sky. At the far end of the sky, strong lights accompanied by flames exploded and flashed, and the target plane then flew to ashes, causing bursts of cheers within the "Chinese Army tent". "Aircraft and air defense weapons are the relationship between spears and shields. Only by fully understanding each other's characteristics can we better 'break the shield' and 'defend the spear'." As he stepped down from the command seat and talked about his cross agency experience, Li Bojun bluntly stated that he had benefited greatly, "Mastering the principles of using air defense forces can effectively improve the battlefield viability of our pilots. Similarly, transforming our flight experience into air defense training can also help air defense units innovate in targeted combat training methods..." Despite Li Bojun's eloquent remarks to reporters, he also had a period of "acclimatization" experience at the beginning of his cross replacement. When I first took up the post of deputy battalion commander of the air defense battalion, the battalion happened to organize the formation of officers. Li Bojun, who was taking part in the homework, picked up the map and couldn't help feeling a bit worried. For Li Bojun, who is accustomed to using aerial maps, the dense contours on the map dazzled his eyes. "It is difficult to read and read the map, let alone complete the homework on the map." Li Bojun told reporters that at the moment, he better understood the original intention of the group military party committee to organize commanders to alternate positions between arms and units that are antagonistic to each other, "Through job rotation, officers and soldiers can grow and improve through mutual understanding and mutual learning, and constantly hone and improve their actual combat capabilities." During the day, they operate equipment together with officers and soldiers of the air defense battalion, and at night, they participate in night classes to learn the theory and tactics of air defense operations... The transition from "Eagle Hunter" to "Eagle Hunter" forces Li Bojun to understand new situations, adapt to new environments, and comprehensively improve their comprehensive qualities. During his tenure, Li Bojun repeatedly participated in live fire shooting in his battalion and achieved outstanding results. Last October, Li Bojun participated in the assessment of officers in the air defense battalion, with excellent overall results. Not only that, Li Bojun also summarized and proposed a new battle method of "helicopter low altitude avoidance of air defense missile attacks" based on his own cross agency work experience and combined with the technical and tactical characteristics of a certain type of air defense missile, which was verified and promoted for use by his land aviation brigade. "The more in-depth understanding of the equipment performance and tactical tactics of air defense units, the more clear we are about the weaknesses of our land and air forces, and where the breakthrough points in the innovation of combat training methods are." Li Bojun told reporters that in the next step, he will combine his own experience in air defense operations and helicopter anti air defense attacks
