The purpose of this study is to analyze the strengths and weaknesses of the ROK Army military doctrine research, and to analyze the external environment to present development plans that the ROK Army military doctrine development department should pursue. This study employs SWOT analysis technique to develop strategies for the ROK Army military doctrine research. First of all, the strength and weakness factors of the ROK Army military doctrine were derived by comparing and analyzing the US Army and the UK military doctrine development research, the ROK joint military doctrine development research, and the Navy and Air Force military doctrine development research. Active promotional activities to improve interest in doctrines and access to them and the operation of advisory members of the development of doctrines were found to be strength factors. On the other hand, insufficient review in selecting the doctrine project, insufficient preparation of the doctrine writing team, insufficient expertise of the doctrine researcher, non-operation of the usual doctrine advisory group, and absence of the doctrine writing guidelines were found to be weakness factors. The opportunity and threat factors were derived by analyzing the external environment of the ROK Army military doctrine research. Opportunity factors were improved conditions for the use of soldiers' smart phones, implementation of executive doctrine evaluations, and expansion of cooperation with other countries and other military doctrine development departments. Threat factors were the decrease in the number of the manual users, the decline in confidence in the doctrinal department, and the demand for the expansion of various information and services. Based on this, SO strategy, ST strategy, WO strategy, and WT strategy were derived, and development plans of the ROK Army military doctrine research was proposed. In the study, 'Strategies for Expanding the Promotion of Doctrines', 'Strategies for Expanding Advisory Committee on the Development of Doctrines', and 'Strategies for Expanding the Evaluation of Executive Doctrines' were presented as SO strategies. As ST strategies, 'Optimized Doctrine Writing Team', 'Improvement of the Expertise of Doctrine Researchers and Retention Strategies', and 'Implementation Strategies for Doctrine Writing Guidelines' were presented. As a WO strategy, 'Strategies for Increasing the Availability of Manual' and 'Establishing Various Doctrinal Information Environments' were proposed. As a WT strategy, 'Establishment of an Advisory Group for the Creation of Doctrines' and 'Strategies for Restoring Confidence in the Doctrine and Doctrine Department' were proposed. The results of this study are expected to provide various practical measures for the development of the ROK Army military doctrine research. However, this study has a limitation because it relied on the empirical knowledge of the researcher and the judgment based on the literature review, and there was not enough general data on the military doctrine development department. Therefore, more researchers' participation is required in military doctrine development.
