Fun fact: the current South Korean president, Moon Jae-in, participated in Operation Paul Bunyan
The idea was to help educate the naive young kids about the realities of North Korea facing off with South Korea by stationing them right on the DMZ.
Also, Moon was not one of the few dozen troops that were on scene with claymore mines. The entire armed forces of S Korea was put on alert at the time and he was in uniform at the time.
> In addition, a 64-man task force of the South Korean Special Forces accompanied them, armed with clubs and trained in taekwondo, supposedly without firearms. However, once they parked their trucks near the Bridge of No Return, they started throwing out the sandbags that lined the truck bottoms, and handing out M16 rifles and M79 grenade launchers that had been concealed below.[3] Several of the commandos also had M18 Claymore mines strapped to their chests with the firing mechanism in their hands, and were shouting at the North Koreans to cross the bridge.[12][13]
