"Man, those Chinese are good soldiers... You can't see 'em; you can't hear 'em. You don't know they're there until they're on top of you... They're experts at camouflage and the best damn night-fighters I've ever seen. We could walk a company over the hill and see nothing. Then we'd look around and they'd be swarming on us like flies. It was just like they'd sprouted from the ground."
