1 is the need of the current international situation.

Multipolarization has become the mainstream in today's world, and the arms race has shifted from quantity to quality. Although peace and development are the themes of today's times, hegemonism and power politics still exist. The international hostile forces deliberately curbed the development of China and tried every means to promote Westernization, with the strategic focus on Taiwan Province Province, Tibet and Xinjiang.

At the same time, they try their best to infiltrate ideas, compete with us for the next generation, or plan subversive activities in an attempt to bring down the state power, or collect intelligence and steal important information such as politics, military affairs, economy, science and technology in China. And there is a crisis in the surrounding environment of China. We must always be vigilant, master the necessary national defense knowledge, and make contributions to the territorial integrity and sovereign independence of the motherland at any time.

2. National defense construction must be strengthened.

Colleges and universities are an important position to cultivate a strong national defense reserve force. Modern high-tech war needs high-quality, high-quality soldiers and strong reserve forces, and the training of military schools is far from meeting the needs of modern war. Colleges and universities, which train senior professional and technical personnel, should bear this responsibility and obligation.

3. It is conducive to cultivating national defense reserve talents and promoting national defense modernization.

China's national defense construction has always adhered to the road of combining a capable standing army with a strong reserve force, which is also the fundamental guiding ideology of China's national defense construction in the new period. As a special social group, college students have high scientific and cultural quality and are easy to master modern scientific and technological knowledge. Doing a good job in national defense education for this group will reserve a large number of high-quality national defense reserve forces with high scientific and cultural quality and certain military skills.

4, when necessary, for the troops to transport high-tech military personnel.

Provide military theory teaching and necessary military training for college students, train high-tech military talents for the army when necessary, become the backbone of the expansion and formation of the wartime army, create conditions for winning future high-tech local wars, and provide a strong guarantee for national defense construction and military struggle preparation. Therefore, carrying out national defense education in colleges and universities is conducive to improving college students' national defense ability.

5. In the future, local wars under high-tech conditions will still adhere to the people's war.

With the rapid development of science and technology and the extensive application of high technology in the military field, although to a certain extent, the traditional way of people's war is out of date. However, the concept of people's war cannot be lost. Under the new situation, the people's war still has its significance. In wars without smoke, such as information warfare and network warfare, folk technical groups will make great achievements. They can give full play to their intelligence and devote themselves to safeguarding national security.
