Abstract
This study suggests a method to improve the reliability of training with war game models by matching the results of the artillery damage assessment of the training units generated in the same situation when linking ChangJo21 and Combat21 models which are training war game models with different resolution. If the results of the artillery damage assessment of the ChangJo21 model and the Combat21 model that occurred in the same situation are not similar at a reasonable level, it is likely that the training unit will distrust the training with the war game models. In this study, the artillery damage assessment logic and formulas of the two models were compared and analyzed to compensate for differences in artillery damage assessment results of the two models, thereby establishing an experimental environment that could occur under the same conditions and generating experimental data. Multiple regression models as calibration models were used to match the artillery damage results of the two models. Each calibration model is statistically significant and highly explanatory.
