US Marines in Iraq have been issued a sonic gun, according to the Daily Mail:
The "Secret Scream" gun as it is called, could revolutionise the way US troops deal with snipers, suicide bombers and riots in the turmoil of post-war Iraq.
The actual sound used is a recording of a baby’s scream played backwards.
"For most people, even if they plug their ears, it will produce the equivalent of an instant migraine," said Woody Norris, chairman of American Technology Corporation, the Californian company that has produced the weapon.
"It will knock some people to their knees."
