Back in the 1990’s I worked with a US chap who’d done an exchange with the South Korean SF. He recalled doing a night time parachute jump with the South Koreans. At the back of the plane were a group of SK ‘rough terrain’ jumpers. He said they were dressed like American football players. Their mission was to jump into the mountainous areas of Korea. According to him their training casualty rates were pretty high, to a level you’d never get away with in a Western military. All were volunteers. He also witnessed a dog and pony show demo at their base with a load of visiting VIPs as part of an ASEAN cross training initiative. One of the Koreans misjudged the fast roping and fell off the roof. No one responded until after that particular phase of the demo was completed, then the medics rushed in.
