The reserve force is an integral part of the People's Liberation Army. It is an effective organizational form of integrating the army with the people and mobilizing quickly. It performs the mission of the People's Army together with the active forces. Reservists are the main body of the reserve force, members of the national armed forces, and an important source of replenishment for active troops in wartime. On December 30, 2022, the 38th Session of the Standing Committee of the 13th National People's Congress voted to pass the Law of the People's Republic of China on Reserve Personnel. The promulgation and implementation of the Reserve Personnel Law marks a breakthrough in the reform of the reserve personnel system. It is of great significance to strengthen the construction of the reserve personnel team under the rule of law, promote the transformation and development of the reserve force, and provide a strong legal guarantee for the construction of a high-quality and professional reserve personnel team. We will comprehensively promote the transformation and reshaping of the reserve forces. At present, the great changes that have not occurred in the world in a century are accelerating the evolution, the instability and uncertainty of China's security situation are increasing, and the military struggle is arduous. Strengthening the construction of the reserve ranks is conducive to the integration of national defense and military construction into the economic and social development system, coordination with the national modernization development, and opening up the transformation path from the national comprehensive strength to advanced combat effectiveness and resistance of the system. It is not only a practical move to promote the high-quality development of our army, but also a strategic choice to liberate and develop combat effectiveness. The 20th National Congress of the Communist Party of China (CPC), proceeding from the overall situation of building a socialist modern country in an all-round way and promoting the great rejuvenation of the Chinese nation in an all-round way, made a strategic plan for national defense and military development, emphasized the comprehensive strengthening of military governance, consolidated and expanded the achievements of national defense and military reform, improved the composition of military forces, and systematically optimized the military policy system. This time, the Reserve Law was promulgated and implemented, implementing the deployment requirements of the CPC Central Committee and the Central Military Commission on the adjustment and reform of the reserve forces, taking military needs as the traction, preparing for war as the direction, and quality construction as the focus, firmly grasping the attribute of reservists as soldiers, and striving to build a complete set of reservists system in the new era with clear guidance, authority, standardization, and system support, It will certainly provide strong institutional support for building a world-class reserve force. "When the law changes with the times, it will be governed, and when it is appropriate to govern the world, it will be meritorious.
