Military science , seeing in history an immense number of examples in which the mass of an army does not correspond with its force , and in which small numbers conquer large ones , vaguely recognises the existence of this unknown factor , and tries to find it sometimes in some geometrical disposition of the troops , sometimes in the superiority of weapons , and most often in the genius of the leaders 历史上有数不清的军队的数量与力量不符合的例子小部队打败大部队,于是军事学上便含糊其辞地承认,有一种未知的因子存在,军事学家力图在几何阵形在军队的装备最常见的在统帅的天才上寻找这一未知的因子。
