In the era of the 4th industrial revolution, new technologies such as artificial intelligence, big data, and cloud are rapidly developing. Artificial intelligence, in particular, is changing the paradigm across all areas, including humanities, society and economy, and this is the same in the defense sector. Worldwide, it is doing a lot of research and investment to strengthen its defense capabilities through artificial intelligence. However, the R·O·K military is still in its early stages in utilizing artificial intelligence. Therefore, it takes a lot of effort to use artificial intelligence as a game changer for future battlefields. In this paper, we analyzed the current status of infrastructure such as data, algorithms and computing resources in order to secure the defense artificial intelligence technology of our military and proposed the development plans. It will help that our defense artificial intelligence technology will be an important starting point for the rapid development and the realization of reliable and efficient national defense.
