Among the five promotion strategies of Defense Innovation 4.0(DI 4.0), the military structure/operation optimizatio n strategy aims to innovate the military structure based on advanced science&technology(S&T), and to integrate ad vanced S&T in the field of defense operation such as education&training and human resource development. As the f uture battlefield expands to AI-based unmanned/robot combat systems, space, cyberspace, and electromagnetic field s, it is necessary to train officers with the capabilities required in these battlefields. It is necessary to develop capab ilities from junior officers who will lead the future battlefield to operating core advanced power based on the 4th ind ustrial revolution S&T. We review the education system of the military in universities and propose a method of red esigning the education system that is compatible with DI 4.0 and can develop technology-intensive capabilities base d on advanced S&T. We propose a operation plan of major and extra-programs that can develop the capabilities of junior officers required for the future battlefield, and also suggest ways to support the army's practical training.
