The stars are silent and the sword is in the sky. In the golden autumn, the air defense unit of a regiment in the Beijing Garrison successfully completed the live fire inspection task with new equipment. Can you accurately hit the target when using new equipment for live fire for the first time? Officers and soldiers face great challenges. The "enemy" plane suddenly arrived, the commander Li Yuehang quickly identified and judged, and the gunner Ren Xiaoyuan accurately operated and locked the target. After hearing the commander's order to shoot, Ren Xiaoyuan fired decisively. With a "flame tongue" breaking through the night sky, the "enemy" aircraft suddenly opened up. "The ability of mission officers and soldiers to calmly handle and confidently respond stems from the intensive research and training of new equipment at ordinary times." According to the leader of the delegation, the gunner needs to skillfully switch between two tracking modes, observe four display and control interfaces all the time, and accurately master eight types of functional operations, "The running in time between people and equipment is tight. Everyone is riveted on the training ground to practice operation against time. With high technology content of equipment, we invite technicians from relevant institutes and manufacturers to the front line for guidance. Without experience in live ammunition shooting of this type of equipment, officers and soldiers actively communicate with brother units equipped with this type of equipment to obtain data support". In the face of difficult and important courses, on the one hand, they greatly shortened the reaction time by practicing speed step by step, timing competition, record breaking and other methods; On the other hand, by setting complex routes and highlighting the difference between day and night, the target stability and tracking ability under repeated multi-mode switching can be effectively improved. At the same time, they also collected and sorted out data, sorted out and compiled more than 30 group training plans, 5 operation textbooks and 1 set of live ammunition shooting operation manual. "War is fought day and night, and soldiers are trained without fear of danger." The officers and soldiers of the regiment said that the new equipment training objectively has a running in process, but once it is installed, we should do our best to speed up the formation of combat effectiveness. It is reported that during this training, they inspected the equipment performance, improved the combat skill level, tempered the fighting style, and successfully completed the scheduled target task.
