This is "Horsemanning" which was a popular photography fad in the where people posed in such a way to appear beheaded. Seems that "Planking" was not such an original idea after all, people have to doing weird stuff in photos since cameras were invented.
This image shows an American soldier risking his life to save two Vietnamese children during a fight. This is bravery. A man risking his life to save the enemy's children Only The American Soldier Would Do This !
