Purpose: The purpose of this paper is to analyze the characteristics of Generation MZ in the reality of the Korean armed forces where most of the enlisted soldiers are Generation MZ, and consider the task of improving the barracks culture for them. Method: Literature study and empirical data were carried out including books, academic journals, and disser-tations related to the barracks culture’s improvement and generation MZ in order to analyze the justification and promotion strategy of barracks culture improvement and a barracks culture improvement plan appropriate for the characteristics of the military organization and Generation MZ. Results: In order to improve the barracks culture appropriate for the characteristics of Generation MZ, the Korean armed forces need such measures as the strengthened authority and responsibility of the soldiers and allowed use of mobile phones. Furthermore, as a measure to establish military discipline, punishment for human rights, security, and negligence related issues need to be strengthened. Generation MZ lack personal experiences, and hence, group counseling ought to also be facilitated. Such policies targeting Generation MZ will be meaning-ful policies for the Generation Alpha who will enlist in the military in the future. Conclusion: Given the nature of the Republic of Korea, which has adopted the conscription system, the military ought to be able to play the role of the last public education institution. The military ought to be able to help the Republic of Korea take a large leap toward becoming a world-class nation by recovering the hopes and dreams which Generation MZ, called the Generation of 7 Losses, lost, and developing on their own. If the military pro-moted barracks culture improvement can create synergies in tandem with the independent and enterprising characteristics of Generation MZ, the Republic of Korea will not only be able to take a new leap forward compa-rable to the miracle of the Han River, but will also become a leading nation qualified to spearhead the future of the world.
