"It is reported that the positioning of the missile satellite receiver is abnormal, and technical support is requested..." On the eve of the National Day, a brigade of the Rocket Army was engaged in a fierce battle for a live firing drill. When the missile entered the imminent firing state, an emergency occurred on the scene. Zhang Kai, a young engineer charged with the task of technical control, quickly entered the engine control module to interpret and analyze the data. In just 2 minutes, the fault was eliminated, ensuring that the missile was launched on time. During the review, Zhang Kai's successful handling of the special case was unanimously recognized by the superior leaders. He said with emotion: "My growth and progress can not be separated from the training of the brigade technical room!" The technical office in Zhang Kai's mouth is a newly established grassroots technical breakthrough department of the brigade after the "neck down" reform. It is responsible for daily training and technical control and situation handling of major tasks, as well as the selection, training, guidance, assessment and evaluation of professional and technical cadres. Prior to this, professional and technical cadres were scattered in each battalion and company, lacking communication when carrying out tasks, which made it difficult to form a joint effort to pool intelligence to tackle key problems, leading to inadequate role of professional and technical cadres. In June 2019, Zhang Kai, as a technical backbone, was selected and transferred to the technical room and incorporated into the missile launch technology check group. Later, Qiu Yi, the group leader and senior engineer, made a training plan tailored to Zhang Kai's weaknesses at the first time. With Qiu Yi's help, Zhang Kai quickly adapted to the needs of his post, and gradually became the backbone of the technical room with the ability of independent technical control and special handling on the battlefield. "As a high-tech service, the Rocket Army is very important for the construction of combat effectiveness to establish a team of professional and technical cadres with reasonable structure." Shen Qiguo, the brigade commander, introduced that they organized professional and technical cadres to relocate, optimize the proportion of allocation, and integrate and simplify the division of specialties based on the actual situation of the brigade equipment transformation; Establish a dynamic grouping of technical support to realize the personnel deployment scheme from a single position to a full element system integration; Organize professional and technical cadres to follow the training of synthetic drills, missile testing, live firing and other tasks, constantly strengthen the ability of technology control and technology application, and accumulate practical experience. With the continuous development of the technical room of the brigade, a group of technical backbones who understand technology, can check and can teach have come to the fore. Since this year, they have successfully completed combat duty, live ammunition launch, joint exercises and other tasks, won four "three small" innovation achievement awards, and carried out scientific and technological empowerment for the brigade to improve its combat effectiveness.
