I hear that the Koreans are even tougher. If you screw up at work or at school your boss or teacher will punch you.
I was stationed in Korea in the mid-90s. Due to my position I had a lot more interaction with the ROK Army and KNP than most US soldiers. I remember seeing junior ROK officers enforce discipline with a steel rod...not an outright beating mind you, but a good, motivational swat with it from time to time.
