National defense is survival knowledge and competition of comprehensive strength based on economy and technology. Its function has three aspects: it is the guarantee of national security, the premise of national independence and the important condition of national prosperity and development.
The country cannot stand defenseless, and the people cannot stand defenseless. As a country and a nation, the most important things are nothing more than two major events. One is development and the other is security. National defense is the product of human social development and security needs. This is a fundamental plan related to the life and death of the country and the nation.

National defense in this language is directly related to national security, national dignity and social development. Modern national defense takes military forces as the core, including related non-military forces; It attaches importance to the country's war potential, especially the mobilization efficiency in wartime.
