The Pentagon's Secret Scream

SOUTH POMFRET, Vt. — Marines arriving in Iraq this month as part of a massive troop rotation will bring with them a high-tech weapon never before used in combat -- or in peacekeeping. The device is a powerful megaphone the size of a satellite dish that can deliver recorded warnings in Arabic and, on command, emit a piercing tone so excruciating to humans, its boosters say, that it causes crowds to disperse, clears buildings and repels intruders.

"[For] most people, even if they plug their ears, [the device] will produce the equivalent of an instant migraine," says Woody Norris, chairman of American Technology Corp., the San Diego firm that produces the weapon. "It will knock [some people] on their knees."

American Technology says its new product "is designed to determine intent, change behavior and support various rules of engagement." The company is careful in its public relations not to refer to the megaphone as a weapon, or to dwell on the debilitating pain American forces will be able to deliver with it. The military has been equally reticent on the subject.

And that's a problem. The new sound weapon might, in some scenarios, save lives. It might provide a good alternative to lethal force in riot situations, as its proponents assert. But the U.S. is making a huge mistake by trying to quietly deploy a new pain-inducing weapon without first airing all of the legal, policy and human rights issues associated with it.

This is a weapon unlike any other used by the military, and it is certain to provoke public outcry and the conspiracy theories that often greet new U.S. military technology. If the military feels that its new-style weaponry brings something important to the battlefield, and if testing has shown it to be safe, then why not make our reasoning -- and research -- transparent to the world?

Nonlethal weapons have been promoted by a small circle of boosters for nearly 15 years as something increasingly necessary for the U.S. military in its growing peacekeeping, urban-combat and force-protection missions. Some of the weaponry championed by the group, like rubber bullets, flash-bang grenades and, more recently, electromuscular disruptive devices, or Tasers, has already been deployed.
