This theoretical lecture was very 'thirst quenching', using the experiences of officers and soldiers to explain the big truths, and strengthening our belief in rooting ourselves in the military camp. Recently, a theoretical service team from an information support unit came to a certain point in the deep mountains to give a theoretical lecture. After listening to the lecture, college student soldier Yang Xin gained a lot. The department has scattered locations and heavy tasks. In order to continuously stimulate the enthusiasm of officers and soldiers for military training and preparation, they invite political instructors, advanced models, and outstanding battalion and company leaders to form a theoretical service team, closely focusing on hot issues of concern to officers and soldiers. They often go to grassroots units and remote locations to give theoretical lectures and answer questions face-to-face for officers and soldiers. We need to use the 'theoretical spark' to light up the hearts of officers and soldiers. ”The leaders of the department introduced that in order to avoid phenomena such as "one size fits all" and "big pot cooking", they pay attention to distinguishing job categories when organizing lectures, and formulate more targeted teaching plans based on current policies and regulations that affect the vital interests of officers and soldiers. Not long ago, a certain brigade was urgently assigned a communication engineering construction task, and the officers and soldiers were under great physical and mental pressure. After understanding the situation, the department included this task point in the propaganda route of the theoretical service team, organized members to write teaching plans based on the characteristics of the team's responsibilities, invited "the most beautiful revolutionary soldier of the new era" Zhao Li to have face-to-face exchanges with officers and soldiers, and guided everyone to unload their ideological burdens and enhance their confidence in overcoming difficulties during casual conversations. The preaching has ended, and the fighting spirit and enthusiasm of the officers and soldiers have significantly improved. The effectiveness of theoretical preaching is closely related to the abilities, qualities, and work achievements of the preaching personnel. ”Liu Zijian, a staff member of the department, said that they extensively selected political cadres and grassroots backbones with strong military and political qualities and rich teaching experience, closely focused on the actual situation of different units, discussed teaching directions in a "one place, one policy" manner, and paid attention to putting effort into the "next article" of helping and solving difficulties. After being selected for the theoretical service team, Sergeant Major Zhuo Zhangming conducted micro lesson guidance around the theme of "unity and cooperation", straightening the "question marks" in the hearts of soldiers through the collision of viewpoints; Political instructor Guo Hongbiao actively interacted with officers and soldiers on the topic of "how to continue to inherit and carry forward excellent work styles in the new era"; Youth is not reserved for youth, hard work forges a sharp sword... "Li Mingxin, a government official, used an adapted poem as an introduction to encourage everyone to seize the day and pursue their dreams in the military camp. The "theoretical spark" shines in remote locations, and the enthusiasm of officers and soldiers for training and preparing for war is even higher. The leaders of the department stated that they will regularly carry out grassroots activities for theoretical services, continue to provide "hot air" and "down-to-earth" theoretical services, and constantly stimulate the motivation of officers and soldiers to root at the grassroots level and contribute to the military camp.
