In the movie, Enemy at the Gates, the German tank comes in roaring - surrender now... - It doesn't work.
Similarly, the government tried this tactic at WACO. With tanks blaring "This is not an attack, this is not an attack, ..."
I think they also tried Nancy Sinatra tapes of "These boots were made for walking..." - That didn't work either.
What would they try in Afghanistan? This burqua was made for lifting?
