At staff college many eons ago, flail tanks were called up to clear refugees from a critical route. It was a map exercise but the student argued, with tongue in cheek, that the sight of the flail tanks coming down the road would cause the refugees to clear the route voluntarily by dispersing rapidly to the ditches and fields.
The DS (Directing Staff) carefully considered the student's argument and allowed the "play". The DS' limitations notwithstanding, the route was 'cleared' and my, I mean:
the syndicate was the only one to successfully move its column up the route that day!
I don't understand the whispers of "bloodthirsty bast*rd" that permeated the Mess that evening!!!
