"赤手空拳发动冲锋might very well be true.But not every one unarmed.usually 1/3 unarmed.This happend in chinese troops in Korean war too.If you look at the battle fields of large scale charge, you see so many weapons on the ground that you can pick up. There is no need for every one to carry a weapon.Just pick up one from ground."

啥时候朝鲜战场上志愿军冲锋的部队有三分之一的人员没有武器了？呵呵。
