After the founding of New China, the foothold of China's national defense and army building is to carry out active defense at home, or to wage a people's war on the mainland. This determines the structural model of our army's mechanized and semi-mechanized army. With the advancement of the new military revolution, the structural contradictions of our army are very prominent. The form of information warfare puts forward three requirements for our military strength structure: First, information firepower matching. In the future battlefield, for a long time, the firepower provided by mechanized weapons and equipment will be combined with certain information warfare forces to carry out combat activities, but it will eventually go through the evolution process of firepower information warfare-information firepower warfare-information warfare. The second is the integration of multidimensional forces. The power structure of information warfare will be a multidimensional combat system of air, ground, sea, sky and electricity. Each power factor plays an irreplaceable role in different stages of war, especially the status of new power factors such as information network warfare power and space power is rising. Third, it has strong strategic mobility. In the non-contact and non-linear combat environment with transparent battlefield and accurate attack, the mechanized combat mode of deploying troops in different positions has been seriously lagging behind, and will be gradually replaced by the deployment of mobile troops supported by information networks. Strategic delivery, especially air delivery power, directly affects and restricts the efficiency of the overall strategic power.

The accelerated development of military high technology makes our army's weapons and equipment construction face severe challenges. The accelerated development of high technology and its wide application in the military field have made a qualitative leap in the operational effectiveness of weapons and equipment and presented a new look on the war stage. First, the integration capability of weapon systems has been significantly enhanced. The C4 ISR system covering air, ground, sea, sky and electricity closely combines the information-based combat platform with the intelligent firepower of precision strike, which makes the weapon and equipment system realize the integration of information firepower and the multiplication of operational efficiency. Second, the ability of attack and defense presents a development trend of mutual support and two-pronged approach. From focusing on the development of offensive weapons such as missiles to emphasizing the development of weapons and equipment systems with both offensive and defensive capabilities. In particular, the United States, Russia, Israel and other countries have begun to actively develop anti-missile defense systems when offensive weapons and equipment have developed to a higher level. Many single weapons developed by various countries also show the trend of both offensive and defensive. Thirdly, the status and performance of mobile devices have been greatly improved. The status of large-scale delivery and long-distance delivery of mobile devices has risen, and the carrying capacity, range and speed have been greatly improved. A nuclear submarine can sail around the earth for several weeks. The flight speed of the plane reaches three times the speed of sound, the range of the fighter plane exceeds 5,000 kilometers, and the strategic bomber exceeds 1.6 million kilometers. If there are aerial tankers and other equipment, it can be delivered across continents or even around the world. Fourth, a large number of new weapons have been successfully developed or made major technological breakthroughs. The development of weapons and equipment has entered new fields such as aerospace and information. The rapid development of weapons and equipment makes the situation of updating our military weapons and equipment very severe.
