South Korea has encountered various non-traditional security threats, prompting calls for an augmented military role in addressing them. Nevertheless, given the persistent presence of traditional threats, the pivotal discourse surrounding the ROK military's role in addressing non-traditional security threats remains little explored. We investigate what the Korean people think about the ROK military's role in responding to non-traditional security threats through surveys. In addition, we subdivide a situation against the non-traditional security threats between peacetime and wartime into several stages (i.e., peacetime, disaster, accident, chaos of public order, impossibility of maintaining public order, and wartime) to analyze what role the ROK military would play at each stage under current law.
