In have a picture somewhere of this guy at some outpost in Vietnam holding up a dead centipede that is at least that long. There was a nice thought to contemplate along with the VC as you settled down in your foxhole for the night.
They loved the holes and niches in bunker sandbag walls. Uou learned not to lean on then for too long. Remember a guy had one crawl into his trousers from the sandbags.
