They are allowed to but not make that "face". They should just keep scowling and remain calm. At least the more skilled and powerful ones. I don't really care if weak ones do it since they are weak after all. A fight becomes less of a fight really when the opponent loses his cool and becomes more impulsive. Its pretty much a factor for defeat in real life as well as fiction. Granted however that you can't expect everyone to be cool headed but veteran soldiers do remain calm in dire situations.
