A lot of Afghanis will cheerfully charge at you thru a hail of bullets, they believe if they get hit, it is the will of Allah and they will go to Paradise if they die. being charged by a man with a big knife, or sword is, however, a different thing altogether. If they have a bit lopped off by an edged weapon, that's how they go into paradise and that is forever. Best not take any chances against a crazy Ferengi who brings a sword to a gun fight. Allah just might be helping HIM!.
A sword, or fixing bayonets is a statement of intent and commitment that they will be getting up close and personal and do not themselves mind dying. A proper Brit bayonet charge against Argentinian troops not all that long ago, who had been resisting strongly, scared the excrement out of them and they surrendered in droves.
