Sorry guys, I'm afraid you got it all wrong! These fellows are the North Korean Very Special Forces though nobody is as yet sure of their precise employment. Either they will show up on the DMZ at high noon and blind the US and South Korean forces by sunlight or in case the sun doesn't cooperate, and that would be a great insult to the great and very much loved leader Kim Kim Kim, the US and South Koreans watching the DMZ will die for laughter. I presume they got the idea from Monty Python!
