As far as I know, this is a true story:
When my brother was stationed in the Sinai Valley with the 101st Airborne back in the late 80's, they used to have an issue with the local Arabs approaching the base trying to sell all manner of things, usually drugs.
Late one night, my brother and his buddy Jack were on duty. The gates were closed and they're sitting in the small guard hut when three Arabs approach trying to sell what they thought was heroine.
They knew a few words of Arabic, but that was it. So they're using them: Stop, go away, no, etc. but the three Arabs aren't giving up. Finally, Jack tells my brother to call the sergeant.
So as my brother steps back into the hut and calls the sergeant and is filling him in on the situation, one of the Arabs starts to climb the fence. Jack yells out, "we got a climber" and my brother informs the sergeant that one of them is starting to climb the fence.
The sergeant tells my brother, "tell him to put a round in his leg". So my brother passes on that messaage.
Jack takes aim and proceeds to turn the Arab's head into a canoe, knocking him off the fence in the process. Then all hell breaks loose with the two remaining Arabs screaming and shaking their fists at them.
The sergeant hears all of it and says, "I'll be right there" and hangs up. 30 seconds later, the sergeant shows up, looks at Jack and says, "how the hell did you ever pass basic? Give me that weapon!"
Jack hands over the M16 and the sergeant immediately turns it on the two remaining Arabs blowing them to kingdom come. Then he tells the two of them to call relief and then bury the bodies and it had better be done before sunrise or they'll be getting buried along with them.
