"Do you carry your sketch book with you everywhere you go? If not, why not?"
During the Korea war, Ridgway gained the nickname, "Old Iron Tits," for his habit of wearing hand grenades attached to his load-bearing equipment at chest level. {Photographs however show he only wore one grenade on one side of his chest; the so-called "grenade" on the other side was in fact a first-aid packet}.
