Expansion: National defense education is an extremely important work, which is closely related to the security and stability of the country. Its significance is not limited to the development of weapons and military training, but also the promotion of national image, national consciousness and cultural quality in a profound sense.

The main contents of national defense education include: the popularization of national defense knowledge, the establishment of national defense concepts and the mastery of national defense skills. The core of this is the cultivation of national defense consciousness. Only with a strong sense of national defense can we closely link national interests with personal interests, so that every citizen can become a loyal guardian of the country and do his best for the country's development and security construction.

For students, national defense education should start from primary school, teach scientific national defense knowledge through various forms of educational activities, strengthen students' national defense awareness, and guide them to correctly look at national security issues. It is necessary to let students understand the profound influence of war, prevent moral education from being simplified and superficial, and truly create an atmosphere in which patriotism runs through the whole people.

For adults, national defense education should pay more attention to practical operation, let citizens know about national defense capability and military strength, learn basic military knowledge and skills, improve their ability to resist external threats and emergencies, and make contributions to the stable development of the country. At the same time, we should also give play to the exemplary role of military personnel, transmit positive energy, and guide the public to better support and cooperate with national defense work.
