For many troops, equipment upgrading means starting from scratch. A key member of a company in a coastal defense brigade of the Army actively responded to new challenges and made every effort to upgrade their capabilities. Look at the transformation of the veterans, "the excellence rate has increased by 7%!" When they got the professional assessment report card of the company's retraining and supplementary training stage, Xiao Gang, the first level sergeant of a company of a coastal defense brigade in the army, who was responsible for the group training task, breathed a sigh of relief. "From scratch, every improvement of achievements is not easy." After the reform of the system and organization, Xiao Gang's battalion "exchanged guns for guns" and installed a new type of surface to air missile. The officers and soldiers of the company ran into a new position, and Xiao Gang was also transferred from the leader of the anti-aircraft artillery squad to the leader of the missile detection squad. In the company, there are 6 squad leaders who are in the same situation as Xiao Gang. Being entrusted with an important task by the company, these veterans have only one idea in mind: learn new equipment quickly and try their best to shorten the combat effectiveness generation time. "Urgent!" When talking about this transformation, veterans mentioned this word most. With professional adjustment and ability transformation, they seem to enter the "breakthrough mode", and the "acceleration key" is pressed for work training. In the past, the battalion used teams as its basic fire unit. Nowadays, the battalion becomes the basic fire unit, and each platoon and each squad is just a link in the combat effectiveness chain. "From solo to synthetic victory, we don't want to drag the whole battalion behind!" Xiao Gang said. But they are confronted with practical difficulties. Previously, the equipment operation was less than 10 steps, but now it has become hundreds. It is not easy to remember the order. For veterans, it is more difficult to learn theory from scratch. "At the beginning of reading the textbook, there were seven or eight new terms in a paragraph, which were all half understood!" Second class Staff Sergeant Wang Hua said frankly that many veterans had low academic qualifications when they joined the army. Although they had completed the academic upgrading in the army and many people had also obtained professional qualification certificates, they often felt "unable to use all their strength" in the face of new equipment and new majors. "I'm worried!" Wang Hua said that before the distribution of new equipment, the camp organized key personnel to study in colleges and universities for simulated operation training, hoping to achieve "people wait for equipment". However, the gap between the informatization degree and structure principle of new and old equipment cannot be crossed with their efforts in a short time. Veterans are anxious, so are battalion and company leaders. Zheng Xiaobo, the instructor of the battalion, said that in the neighboring units, the battalion's technical office and each company had technical cadres and senior soldiers who knew their specialty, and they had to start from scratch to cultivate talents and fill in the gaps, which was by no means an overnight effort. On the one hand, new equipment has been allocated in place, which is urgent for officers and soldiers to get familiar with; On the one hand, there is a shortage of professional and technical backbones, and the team training personnel are short handed. In the month when the equipment was packed, Xiao Gang and some veterans packed their bags and went to the neighboring troops to "learn from". Others can recite theories for 10 minutes, and they spend an hour to memorize them; Others can understand it after reading it several times. They have to turn over the circuit diagram; Three finger thick equipment theory textbooks, Xiao Gang crammed them into his brain to digest slowly; Wang Hua recorded the teaching process on DV, and then carefully pondered it after turning off the light... In the middle of the training, the superior informed him to organize periodic assessment. Xiao Gang and Wang Hua made a special trip back to the company, used a week to teach their comrades how to operate, and then left in a hurry. Three months later, the veterans lost weight, but
