"赤手空拳發動衝鋒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."

啥時候朝鮮戰場上志願軍衝鋒的部隊有三分之一的人員沒有武器了？呵呵。
