All American soldiers are wearing a colored US Flag on their right shoulder. The American flag patch is full-color only when worn in garrison, but subdued when worn in the field or while deployed. These soldiers are in the field and therefore the patch should be subdued.
North Korea is a totalitarian dictatorship which prohibits common citizens from possession of weapons. Therefore, the North Korean farmer would NEVER have a rifle which he pulled on the U.S. soldiers at the farmhouse.
In previous decades, North Korea has tried to tunnel under the DMZ into South Korea. The U.S. and South Korean forces have interrupted many of these attempts. Therefore, the U.S. and North Korean would NEVER allow an incursion tunnel to exist under the DMZ with an open entrance on both ends accessible by either side.
