This study proposes an integrated Multi-Criteria Decision-Making (MCDM) model using AHP (Analytic Hierarchy Process) and TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) to select the optimal alternative for the Next-Generation Korean Rifle project. While the current K2 and K2C1 platforms have served as the backbone of the Republic of Korea Armed Forces, evolving operational environments and global trends toward modularity and high-power ammunition necessitate a systematic modernization strategy. The research defines seven major criteria—including combat effectiveness, ergonomics, reliability, and networking fusion—to evaluate four strategic alternatives. The analysis reveals that a new 5.56mm modular platform is the most viable optimal choice, offering a superior balance between ergonomic design, technological scalability for the Warrior Platform, and operational reliability. While 6.8mm platforms offer higher lethality, they face challenges regarding cost and technical readiness. The findings provide a quantitative framework for decision-makers in weapon system acquisition, emphasizing the transition from a standalone firearm to an integrated combat system for the future’s war environment.
