In the context of the era of "new engineering" and "national defense science and technology innovation", the society has put forward new requirements for the training and construction of national defense science and technology engineering talents, and the previous talent training model is difficult to meet the needs of comprehensive talent training with interdisciplinary ability, innovative spirit, practical experience, patriotic feelings and global vision. The low degree of attention paid to national defense education has seriously hindered the development of national defense science and technology projects and made it difficult to meet the demand for technology and personnel for modern warfare. This paper analyzes the research status of domestic experts and scholars on these problems by studying the problems and causes of talent training in the new era, and proposes to accelerate the national defense-oriented update of teaching content from "integrating international thinking, eliminating disciplinary boundaries, and innovating teaching methods", from "stimulating innovation potential and uniting military enterprises" to cultivate students' practical ability of national defense engineering, and from "planting patriotic roots and teaching national defense learning" Deepen the national defense ideological and political education for the country and the people, and carry out innovation in the training mode of national defense science and technology engineering personnel in three aspects. This paper mainly expands in the following two aspects: first, to promote the innovation of teaching resources oriented to military industrial technology guided by national defense science and technology projects, and second, to unite leading enterprises in the military industry to deepen the education path of integration of industry and education. These reform measures are of great significance in promoting modern military technological innovation, cultivating outstanding military scientific and technological personnel in an all-round way, and building a united front for national defense and security.
