In modern warfare, the technical content of weapons and equipment is getting higher and higher, and new strategic ideas and means of war are emerging one after another. College students have more scientific and cultural knowledge and higher intelligence level. If they are actively and reasonably guided and educated, they will surely become the backbone of China's national defense reserve forces under the conditions of high-tech war. Therefore, the CMC gradually shifted the focus of the construction of national defense reserve forces from ordinary citizens to college students. In addition, they are also an important source of our military officers. The revised military service law clearly stipulates that officers in active service can be recruited from fresh graduates of local colleges and universities. This is of great benefit to improving the overall scientific and technological level of our army and enhancing its combat capability under high-tech conditions.

However, we should see that negative thoughts such as "I don't know what's going on in the world, only reading sage books" and "Military and state affairs, what's going on in the world, it's none of my business" still have a certain market in colleges and universities. Many college students lack basic knowledge of national defense, and they don't know enough about the national security situation and national defense policies, which affects the backbone role of college students in the construction of national defense reserve forces to some extent. In order to change this situation, we must strengthen national defense education in colleges and universities. This is not only conducive to national defense construction, but also to enhancing college students' sense of patriotism and national hardship.

Popularizing national defense education in colleges and universities requires a lot of concrete work, and centralized military training is a very important part of it. The Military Service Law stipulates: "Students in institutions of higher learning must receive basic military training during their schooling. According to the needs of national defense construction, students who are suitable for serving as officers will be given short-term intensive training. Those who pass the examination shall be approved by the military organs and serve in the reserve of officers. " After years of hard work, military training in colleges and universities in China has gradually become institutionalized, scientific and standardized. Its significance is not only the national defense strategy, but also the rapid improvement of college students' quality. Military training has significantly improved their thinking, style, discipline, morality, style of study, self-management and collectivism. Therefore, military training has become an important way of quality education in colleges and universities, and its achievements have greatly promoted the construction of study style and school spirit.
