Occasionally, there are combat situations which one or both forces can´t terminate the combat using selected combat termination rule according to given relationship between ratio of attrition rate coefficient and threshold values. In this study, we classify the situations that one or both forces can´t terminate the combat with selected combat termination rule into four conditions. Condition${circled1}$ is the situation which both Blue and Red can terminate the combat using all selected combat termination rules. condition${circled2}$ and condition${circled3}$ are those which neither Blue or Red can terminate the combat using selected proportional decision rule, and condition${circled4}$ is that which both Blue and Red can´t terminate the combat using selected proportional decision rule. We analyze the effect of combat termination rules on parity number, final combat power, and combat durations for each conditions. Also, we propose the method to apply the analyzed effect of combat termination rules to combat analysis.
