From a New York Times article by Dexter Filkins on the current offensive in Fallujah:

"And for a time, this frightening urban battlefield became a pulsing cacophony of strange and deadly sounds. The mosques in the city broadcast calls to jihad through their speakers. F-18s fired 3,000 rounds a minute in bursts that sounded oddly like burps. AC-130 gunships droned overhead, their big cannons going thunk, thunk as they found targets.

"Perhaps strangest of all, the American troops brought in their own "psyops" trucks — for psychological operations — and blared sounds that created a nightmarish duet with the mosques: old AC-DC songs, something that sounded like a sonar ping, the cavalry charge."

I'm hoping that perhaps just the right old AC/DC song will cause a fanatic or two to have misgivings about the imposition of Islamist doctrine in the city. I know it would work for me.
