They are going against what God has created them for, only a man should fight as he is the one with capable temperament, unlike a man God did not give a woman impulse control, so in a fight they will inflict horrible and grotesque injuries that their victim may never heal from. This is why any woman who fights must either be put to death or sterilized so she does not pass on her ways to her children.
Deuteronomy 25:11 "If two men are fighting and the wife of one of them comes to rescue her husband from his assailant, and she reaches out and seizes him by his private parts, you shall cut off her hand. Show her no pity."
