At one of the numerous fire support bases I was at we had a Korean fire base down the road about 1/4 mile. One night we saw a man with a load of firewood/kindling leave the woodline a little up the road from us, heading past us and the Koreans for a village. the road had a 6:00 PM curfew and this was about 5:45. We watched as he hurried along, but knew he was late. Sure enough, at exactly 6:00 PM he was directly across from the Koreans - enough said, another 15 minutes and he would have made it home.
The Koreans did not screw around. To them red was red and blue was blue, there were no wishy washy answers. 6:00 PM was 6:00 PM and at 6:01 PM you got fired up if you were on the roads.
