兵势篇 NO.1：

孙子曰： 凡治众如治寡，分数是也；
斗众如斗寡，形名是也；
三军之众，可使必受敌而无败者，奇正是也；
兵之所加，如以瑕投卵者，虚实是也。

这句啥意思：

治理大军团就象治理小部队一样有效，是依靠合理的组织、结构、编制；
指挥大军团作战就象指挥小部队作战一样到位，是依靠明确、高效的信号指挥系统；
整个部队与敌对抗而不会失败，是依靠正确运用“奇正”的变化；
攻击敌军，如同用石头砸鸡蛋一样容易，关键在于以实击虚。

英文这么说：

Sun Tzu said: The control of a large force is the same principle as the control of a few men:it is merely a question of dividing up their numbers.
Fighting with a large army under your command is nowise different from fighting with a small one:it is merely a question of instituting signs and signals.
To ensure that your whole host may withstand the brunt of the enemy's attack and remain unshaken--this is effected by maneuvers direct and indirect.
That the impact of your army may be like a grindstone dashed against an egg--this is effected by the science of weak points and strong.
