班裡正在進行「視力訓練」。一個聰明伶俐的新兵被班長叫出來數遠處曠野上採掘隊的人數。採掘隊在很遠的地方，那些人看起來只是一些小點兒。但是這個新兵毫不猶豫的回答：

　　「十六個士兵和一個中士，長官。」

　　「正確。可你如何知道那兒有一個中士？」

　　「他不幹活，長官。」

Visual Training

The squad were having "visual training". One smart recruit was asked by the officer to count how many men composed a digging party in a distant field. The party was so far away that the men appeared as mere dots, but unhesitatingly the recruit replied:

"Sexteen men and a sergeant, sir."

"Right; but how do you know there's a sergeant there?"

"He's not doing any digging, sir."
