She probably weighs about 60 pounds. She looks like an anorexic. I am amazed how thin these NK soldiers are. The supposedly get the best food, apparently not good enough. Compare them to the RoK soldiers, who are in generally in very good shape, these NK soldiers are tiny. An no armor of any kind. I like the food idea. Have massive picnics where they can see.
She doesn't look anorexic to me. The guys don't look that thin either. A bit rangy perhaps, but not emaciated. Also, how do you know they're tiny? There's really nothing in the picture to base them on. Have you seen any elsewhere?
I know that they have their tallest folk go to Panmujon, as does the ROK (5' 10" is the requirement I think) and even the U.S. (6'+ IIRC).
That said, in any conflict the ROK would wipe the floor with the NKs. Superior training, equipment, morale, logistical system, everything that matters.
