I was told this story by a former British Lieutenant who had been to the Falklands. This is post-WW2, the guy swears it's real but you're buying it at the same price I'm selling it
So there was this Gurkha unit on parade, and the CO was haranguing them. He went on and said : "Shortly you are going to receive instruction on jumping from an airplane at 500ft"!
At this all the troops got rather agitated, which was something very unusual for Gurkhas, and at the end of the parade they broke ranks, visibly unhappy.
So that night the CO called the senior NCO to see what was so wrong with the troops.
"Well, Sir, it's about this business of jumping from airplanes at 500ft..."
"What about it?"
"The troops would like to ask whether they could jump from 100ft instead!"
"100ft? That's impossible! The parachutes wouldn't even begin to open!"
"Oooooooh, parachutes! We hadn't understood that! All right, if we are going to have parachutes no problem with the 500ft!!"
