This study presents simulated results using AWAM for the combat effectiveness of the Warrior Platform improvement. The Army is promoting for a three-stage project that will improve the effectiveness in five fields, including the survivability of warrior, in order to upgrade the platform(i.e. gears, equipments, clothing, etc). This study analyzed the improvement effects of the Dot sight, magnifying glass, bulletproof clothing, and bulletproof helmet of the first stage project, focusing on viability and lethality. Advancement of Dot sight and magnifying glass increases firearms hit rate, and improvement of bulletproof clothing and helmet progress the protection of body parts. The firearms hit rate data were obtained through combat experiments using KCTC Miles equipment. In addition to a degree of improvement of body part protection, the manual data were analyzed and entered as the AWAM's basic data. The analysis indicator utilizes the probability of kill in terms of lethality and the probability of survive in terms of the viability as the main indicator, but also additional consideration is given to the loss exchange rate. The enemy and allied platoon scale of experimental group was organized. The eight scenarios were applied to simulate and produce results in order to statistically compare before and after improvement. The analysis showed that the probability of enemy kill in terms of lethality increased by an average of 1.5 times. Multiple regression analyses also confirmed that the survival rate of the allies, contribution of firearms, and the firing rate of the firearms have a crucial impact on the loss exchange rate. This study has a significant in that the results were quantitatively analyzed by applying statistical techniques and by linking the combat experiments with the simulation to verify the effectiveness of the Warrior Platform improvement for the first time in the Army.
