A brigade of the 72nd group army Independent innovation helps battlefield repair Special correspondent Tong Zujing and correspondent Gong Peiwen reported that in mid July, an amphibious comprehensive exercise of a brigade of the 72nd group army was vigorously carried out in a strange water area. "The transport vehicle was hit by 'enemy' fire, and the door was seriously damaged." Amid the smoke of gunpowder, Feng Qiang, the leader of the emergency repair team, quickly remotely controlled the unmanned transport vehicle, sent the maintenance equipment to the "battle damage" equipment location, and used new technology to carry out emergency repair operations. "In a sense, fighting is fighting support. In the future, the battlefield will be highly informationized, fast-paced and heavily damaged, which requires that the battlefield repair must be fast and efficient." The leader of the support department of the brigade said that the way of battlefield repair must be continuously improved following the evolution of combat means and war forms. To this end, they focused on the key and difficult issues of battlefield support and wartime maintenance support actions, carried out normalized cooperation with scientific research institutions, and introduced new technologies to improve the scientific and technological content of wartime support. According to the leaders of the brigade, they also focused on the needs of the battlefield, aimed at the problems of emergency repair, carried out independent innovation of equipment, selected technical backbones, established a technical maintenance room to carry out research and tackle key problems, and independently innovated and developed a number of new maintenance equipment, such as unmanned conveyor vehicles, heavy-duty unmanned aerial vehicles, intelligent precision cold welding machines, which played an important role in battlefield maintenance support. Not long ago, the brigade organized a maritime equipment rescue and repair drill. A certain type of combat vehicle was suddenly hit by "enemy" fire, and its body leaked and lost power. At the critical moment, the driver guojianyong decisively started the gas cylinder. In just a few tens of seconds, the airbag units preset on both sides of the car body inflated rapidly, effectively slowing down the sinking speed of the chariot. "In the past, the operation of emergency buoyancy aids required passengers to hang out of the cabin, which was time-consuming and laborious, and the effect was poor." Guojianyong told reporters that the reformed floating aid device can realize in cabin control, which not only greatly shortens the start-up time, but also reduces the exposure risk of the operator.
