Observation sample The Joint Operations College of National Defense University makes today's classes connect with tomorrow's battlefield, from military staff officers to joint staff officers. In the tide of the reform of the era of building a strong military, this training class came into being, "The report of the 20th National Congress of the Communist Party of China emphasizes building a new military talent training system, which provides theoretical guidance and action guidance for us to strengthen military talent training." Yang Feilong, a professor of the Joint Operations School of the National Defense University, said with deep feelings, "In the new military personnel training system, the training of joint staff officers is an indispensable part." Two months ago, Yang Feilong attended the opening ceremony of the latest joint post qualification training class. Looking at the group of new students in front of him, Yang Feilong's thoughts could not help being drawn back to 2017. In that year, the work of the joint command organizations in all theatres accelerated and the joint operation capability was generated. All of them were eager for high-quality joint staff officers. It was in that year that the Military Commission entrusted the training task of pre serving staff officers for all military joint posts to the newly restructured Joint Operations Academy. Yang Feilong, the director of the Department of Education and Research of the Army Staff, took the lead in establishing a new Department of Education and Research to undertake the task of training staff officers for joint operations. During that period, Yang Feilong clearly felt the urgent need for joint staff personnel at all levels. From the CMC organs to the theater forces, he kept asking for information and receiving calls and letters. "In the joint operation talent team, the joint operation staff officer is regarded as the 'brain' and 'hands' of the joint operation command officer. Without a professional joint operation staff officer, there is no joint operation capability." Yang Feilong said. Since the 18th National Congress of the Communist Party of China (CPC), President Xi Jinping has repeatedly stressed the need to strengthen the training of high-quality joint operation command and staff officers. Yang Feilong felt the honor and importance of his mission because of the commander's concern. On October 10, 2017, the first joint post qualification training course of the whole army was officially opened in the Joint Operations Academy, and a group of students selected from the whole army entered the campus. "In our first lesson, the instructor was a general." Peng Bing, the first air force cadet, has worked in the Joint Staff Department of a theater for more than 4 years. Peng Bing still remembers the scene five years ago. Since the first class of the whole army, nearly half of the graduates of this class have been selected to join the joint staff posts in the war zones. Joint staff training has also become a "golden signboard" for personnel training in the Joint Operations Academy. Soon after the victory of the 20th National Congress of the Communist Party of China (CPC) from the classroom seat to the joint command skills competition with the theme of "learning to report, taking the mission and practicing skills to become first-class" was held in the joint post qualification training class. Li Can, an army cadet and a battalion commander, stood out from 22 players by virtue of his accurate grasp of the battlefield situation and his first-hand standardized mapping technology. In this assessment and competition, we have set up manual plotting of battlefield situation map, information system based plotting of leader's determination map, command skill knowledge competition and manual chess team competition, both individual projects and team projects, to test the learning effect of students' joint staff skills. "While strengthening the use of information means, the martial arts competition also highlights the mastery of traditional skills to help our staff improve their reading and writing
