On the training ground of a certain squadron of the Zhangjiajie Branch of the Hunan Armed Police Force, a 30 meter x 2 snake race training is underway. The coach closely monitors every movement of the soldiers, and there is also an "eye" nearby that watches and records everything that happens on the training ground. This is our coach's' electronic eye ' The cadre of the squadron, Cheng Zhengliang, pointed to a high-definition camera and said, "With the help of training videos, coaches can discover some subtle details." According to him, as early as a few years ago, the squadron had equipped the squadron with high-definition cameras for regular training, but it still experienced some setbacks to make it truly effective. At first, due to a lack of experience and improper placement and angle of the camera, the recorded footage could not be used for auxiliary training analysis. Some officers and soldiers did not buy it: "The problems found in the video were basically what had already been discovered during group training" "Instead of spending time reviewing the video, it is better to take the opportunity to train for a while"... Is it really useless? Originally, Cheng Zhengliang had confidence in this. He usually watches sports news, and reports often mention that athletes record videos during training or competitions to improve their technical movements. Just as Cheng Zhengliang was wavering, a turning point appeared. Last year, Private Qian Xinhang failed multiple rounds of live fire shooting with light weapons. For this reason, the coach provided one-on-one coaching, but the problem was never found. During the shooting training that day, Cheng Zhengliang was observing the situation on the edge of the training field when he suddenly had a flash of inspiration: Qian Xinhang's poor performance, is it possible that it was caused by the deformation of his hand movements during firing? This is not groundless. During live fire shooting, for safety reasons, coaches can only stand behind the shooter, which creates a blind spot in their line of sight and prevents them from seeing the soldier's hand movements at the moment of firing. To confirm the speculation, Cheng Zhengliang asked the duty officer to bring a camera and place it in front of Qian Xinhang's left side, aiming the camera at his upper body and hands. After the training, Cheng Zhengliang and the coach went to the squadron learning room to watch Qian Xinhang's training video. He blinked suddenly and his fingers shook Looking back at the video frame by frame, they found that at the moment of pulling the trigger, Qian Xinhang's unconscious small movements affected the stability of the gun body. This is a detail we overlooked before After finding the problem, the coach was very emotional. Subsequently, the key members of Qian Xinhang's class monitor helped him overcome his habit of blinking when firing through methods such as tying balloons, resulting in a significant improvement in his shooting performance. The camera is really useful After this incident, the attitude of the officers and soldiers of the squadron changed and they began to think about how to use cameras to assist in training and improve the quality and efficiency of training. During that period, the squadron organized night guard counter attack training, where sentries needed to quickly subdue "criminals" under low light conditions, which placed high demands on reaction speed and action accuracy. However, due to insufficient nighttime lighting, it is difficult for coaches to see the details of the sentinel's movements clearly, which poses significant difficulties in providing targeted guidance. We can ask the camera to help At this moment, some officers and soldiers remembered that the squadron's cameras have infrared night vision function, which can capture images that cannot be seen by the naked eye in dark environments. So, in the following night training, they set up cameras, turned on night vision mode, and recorded the entire process of anti attack training. Through analyzing training videos, coaches found that some soldiers are not familiar enough with weapon operation; Some soldiers, when dealing with attacks from "criminals", fail to grasp the timing of defense... Afterwards, coaches organize intensive training to address the problems discovered. Nowadays, cameras often appear in the training of this squadron, becoming a good helper for coaches - high-definition recording and playback functions make training details that cannot be captured by the naked eye clear at a glance; The night vision function exposes the problems that exist during nighttime training... As detailed issues are discovered and corrected one by one, the training performance of officers and soldiers continues to improve. (New Society)
