National defense mobilization is born of war and prepared for war. Serving the main battle and ensuring victory is the mission of the national defense mobilization system. As a national defense mobilizer in the new era, it is necessary to conduct actual combat against the benchmark, improve military skills, lay a solid foundation, and ensure a smooth start of national defense mobilization construction in the new year. "After a long time, people don't know the soldiers." Long-term peace, far away from the smoke, obscures the eyes of some people who patrol day and night, and paralyzes the nerves of thinking about danger and fighting. On the Internet, you will also hear fallacies from time to time that question the significance of the people's war and ridicule the role of the reserve forces. We must stand firm and resolutely refute it. The military and local governments should make joint efforts to strengthen national defense education, innovate educational methods, actively use "internet plus" and "new media+"to improve the quality and efficiency of education, and earnestly create a good atmosphere in the whole society that cares about and attaches importance to national defense, and does not forget danger and death. "Industry is good at diligence and waste on play, and technology is good at specialization and waste on dispersion." It is the duty and task of national defense mobilization in the new period to practice martial arts hard. At present, with the rapid development of military science and technology, the means of combat and training are constantly updated and iterated, and the links of mobilization and support are becoming more and more complicated and numerous. It is necessary to study and study the knowledge of national defense mobilization in the new era and improve the skills of national defense mobilization as a key task, lay a solid theoretical foundation in in-depth research and accumulation, sharpen excellent quality in dealing with major tasks and special circumstances, grow into qualified national defense mobilization talents through repeated tempering, and better undertake the missions and tasks entrusted by the new era. The construction of national defense mobilization should not only be satisfied with how many plans have been prepared, how many materials have been reserved, and how many inspections have been carried out, but should be brave enough to go to the battlefield and be close to the battlefield, highlight its position and role in actual combat testing and crisis tempering, strengthen the command system, expose contradictions, and clarify responsibilities and objectives. At the beginning of last year, in the face of the sudden COVID-19 epidemic, the national defense mobilization system cooperated with the military and the local authorities, rushed to the epidemic area, and promoted the resumption of production, which contributed an important force and played a prominent role in winning this war without smoke. At the same time, through this big exam, the problems and shortcomings existing in the construction and development were found and sorted out, which provided valuable reference for planning the national defense mobilization construction in the new period. "People who are good at treating diseases will cure their sick places; Those who are good at keeping disadvantages will plug the source of their disadvantages. " After the reconstruction of the national defense mobilization system, the functions and missions have been expanded, the personnel composition has been diversified, and some new situations and problems have emerged in the development and construction, which need to be studied and solved. However, in practice, it is found that some units have insufficient leadership responsibilities, dare not touch the deep-seated contradictions that restrict the construction and development of units, blindly seek stability, delay the construction and development, and affect the generation of combat effectiveness. In view of this, we should vigorously advocate the spirit of "clearing old accounts, seeking new opportunities and breaking through difficulties", identify the contradictory basis of the problem, implement the responsibility of the leading group, make efforts to resolve contradictions and open up obstacles, and take responsibility as the answer to the question of whether the war can be defeated.
