比如为了发挥手榴弹的作用会指定一批人不带枪这样可以多
带一些手榴弹. 第一次世界大战的时候就发现charging时候
如果所有士兵佩带标准制式武器会极大降低速度.

It is estimated a great portion of charging
soldiers would be killed before reaching the
enemy' trench anyway. So it is not an issue
what you should do when you can actually
reach the enemy's trench and find yourself
used up all frenade and has no rifle.

War is war. Soldiers are expendable materials
like anything lese
