A few days ago, my comrades in arms and I jointly developed a certain type of drug detection instrument, which was successfully applied in training practice and won high praise from the superiors. When talking about this innovative achievement, we should start from the failure of a drill. It was a night combat support exercise under the background of actual combat. The "enemy" satellite is in the air, a small number of "enemy agents" are harassing, and the road ahead is damaged... The battle has entered a white hot stage, and special situations have emerged in an endless stream with the upgrading of the exercise. "Boom!" Suddenly, a dull explosion came from the periphery of the position. Immediately, the guidance and investigation team determined that our side was "attacked by biological and chemical weapons, and two soldiers were 'injured'.". My comrades in arms and I immediately went to the scene of the incident to conduct reconnaissance. It is found through inspection that the two "wounded" are typical signs of "poisoning", but the specific source of poisoning needs to be further identified and verified. "The sealing and control group quickly sealed and guarded, the sampling group sampled the air and soil, and the washing and elimination group prepared for washing and elimination..." in the face of chemical substances that are not yet clear, I, as the team leader, issued several commands continuously. The training of real poison detection at night is recognized as a dangerous and difficult course. In general, to complete the identification of a toxic agent, it is necessary to comprehensively use multi-channel procedures. In order to ensure the accuracy of the conclusion, I had no choice but to turn on the strong light flashlight that I carried with me, carefully irradiated around the crater, and then carefully sampled the soil... After a while, I finally succeeded in locking the toxic substances. The on-site commander quickly adjusted the operational deployment according to the detection results. "Your company's mission has failed because of the 'enemy's' precise attack!" However, just as we were about to start the next decontamination work, there was a report from the radio. It turned out that it was my turn on the bright flashlight to observe the crater that exposed my position. "The purpose of night training is to improve the combat ability of the troops under dark night conditions. The use of strong light flashlight undoubtedly reduces the difficulty of training, but it is also easy to cause exposure." "if you don't pay attention to details now, you may lose the overall situation in the future battlefield"... At the resumption meeting, the comments of the guidance and coordination team made me feel mixed. "It is very difficult to detect the real poison in the dark, and the slightest carelessness will lead to danger. Moreover, without the help of light, we simply can not accurately identify the color of the poison source." "how can we complete the task with high standards without the support of scientific methods"... I poured out my own bitter water, which is also a puzzle in the hearts of many comrades in arms. "Practical night training is not simply moving the daytime training subjects to the night, nor can we use the daytime training thinking to deal with the night battlefield. To explore and master the winning mechanism of night combat, we should not only work hard on the innovation of concepts and methods, but also think more about equipment innovation and technology update." The remarks of the regimental commander opened another window for our minds. "We should not only refine our martial arts, but also find out the temperament of our equipment and equipment. Only in this way can we increase our chances of winning on the battlefield." Since then, we have taken this opportunity to find out in depth the concepts and practices that are not in line with the actual combat: for the sake of convenience, equipment maintenance begins to operate when it is simply powered on; On the day of the parking lot, the equipment maintenance is completed by wiping the dust and butter... For a while, some problems with "false light" have surfaced. At the same time, the regiment has set up a training atmosphere supervision group and equipment
