WASHINGTON – Saddam Hussein had been gone just a few weeks, and U.S. forces in Fallujah, west of Baghdad, were already being called unwelcome invaders. One of the first big anti-American protests of the war escalated into shootouts that left 18 Iraqis dead and 78 wounded.
It would be a familiar scene in Iraq’s next few years: Crowds gather, insurgents mingle with civilians. Troops open fire, and innocents die.

All the while, according to internal military correspondence obtained by The Associated Press, American commanders were telling Washington that many civilian casualties could be avoided by using a new non-lethal weapon developed over the past decade.

Military leaders repeatedly and urgently requested – and were denied – the device, which uses energy beams instead of bullets and lets soldiers break up unruly crowds without firing a shot.

It’s a ray gun that neither kills nor maims, but the Pentagon has refused to deploy it out of concern that the weapon itself might be seen as a torture device.

Perched on a Humvee or a flatbed truck, the Active Denial System gives people hit by the invisible beam the sense that their skin is on fire. They move out of the way quickly and without injury.

On April 30, 2003, two days after the first Fallujah incident, Gene McCall, then the top scientist at Air Force Space Command in Colorado, typed out a two-sentence e-mail to General Richard Myers, chairman of the Joint Chiefs of Staff.

“I am convinced that the tragedy at Fallujah would not have occurred if an Active Denial System had been there,” Mr. McCall told General Myers, according to the e-mail obtained by AP. The system should become “an immediate priority,” Mr. McCall said.

General Myers referred Mr. McCall’s message to his staff, according to the e-mail chain.

Mr. McCall, who retired from government in November 2003, remains convinced the system would have saved lives in Iraq.

“How this has been handled is kind of a national scandal,” Mr. McCall said by telephone from his home in Florida.

A few months after Mr. McCall’s message, in August 2003, Richard Natonski, a Marine Corps brigadier general who had just returned from Iraq, filed an “urgent” request with officials in Washington for the energy-beam device.

The device would minimize what General Natonski described as the “CNN Effect” – the instantaneous relay of images depicting American troops as aggressors.

A year later, General Natonski, by then promoted to major general, again asked for the system, saying a compact and mobile version was “urgently needed,” particularly in urban settings.

General Natonski, now a three-star general, is the Marine Corps’ deputy commandant for plans, policies and operations. He did not respond to an interview request.

In October 2004, the commander of the 2nd Marine Expeditionary Force “enthusiastically” endorsed General Natonski’s request. Lieutenant General James Amos said it was “critical” for Marines in Iraq to have the system.

Senior officers in Iraq have continued to make the case. One December 2006 request noted that as American forces are drawn down, the non-lethal weapon “will provide excellent means for economy of force.”

The main reason the tool has been missing in action is public perception. With memories of the Abu Ghraib prison scandal still fresh, the Pentagon is reluctant to give troops a space-age device that could be misconstrued as a torture machine.

“We want to just make sure that all the conditions are right, so when it is able to be deployed the system performs as predicted – that there isn’t any negative fallout,” said Colonel Kirk Hymes, head of the Defense Department’s Joint Non-Lethal Weapons Directorate.

Reviews by military lawyers concluded it is a lawful weapon under current rules governing the conflicts in Iraq and Afghanistan, according to a Nov. 15 document prepared by Marine Corps officials in western Iraq.

Private organizations remain concerned, however, because documentation that supports the testing and legal reviews is classified. There’s no way to independently verify the Pentagon’s claims, said Stephen Goose of Human Rights Watch in Washington.

“We think that any time you have an emerging technology that’s based on novel physical principles, that this deserves the highest level of scrutiny,” Mr. Goose said. “And we really haven’t had that.”

Another issue for the weapon is cost.

The Pentagon has spent $62 million developing and testing the system over the past decade, a scant amount compared to other high-profile, multibillion-dollar military programs.

Still, officials say the technology is too expensive, although they won’t say what it costs to build. They cite engineering challenges as another obstacle, although one American defense contractor says it has a model ready for production.

For now, there’s no firm schedule for when the system might be made and delivered to troops.

Commanders in Iraq say the go-slow approach has had devastating consequences.

There’s no way to calculate how many civilian deaths could have been avoided had the energy beam been available in Iraq. The bulk of the civilian casualties are due to sectarian warfare.

According to AP statistics, more than 27,400 Iraqi civilians have been killed and more than 31,000 wounded in war-related violence just since the new government took office in April 2005.

The Active Denial System is a directed-energy device, although it is not a laser or a microwave. It uses a large, dish-shaped antenna and a long, V-shaped arm to send an invisible beam of waves to a target as far away as 500 yards.

With the unit mounted on the back of a vehicle, U.S. troops can operate a safe distance from rocks, Molotov cocktails and small-arms fire.

The beam penetrates the skin slightly, just enough to cause intense pain. The beam goes through clothing as well as windows, but can be blocked by thicker materials, such as metal or concrete.

The system was developed by the Air Force Research Laboratory in New Mexico. During more than 12 years of testing, only two injuries requiring medical attention have been reported; both were second-degree burns, according to the Joint Non-Lethal Weapons Directorate Web site.

Prototype units have been assembled by the military, the most promising being a larger model that sits on the back of a flatbed truck. This single unit, known as System 2, could be sent to Iraq as early as next year, according to Colonel Hymes of the Joint Non-Lethal Weapons Directorate.

Colonel Hymes’ office, which nurtures promising technologies that can be used by the military branches, plans to spend $9 million over the next two years on the effort.

Money for additional systems isn’t likely to be available until 2010, when an Air Force command in Massachusetts is expected to take control of the program, he said.

Recognizing the potential market, defense contractor Raytheon has invested its own money to build a version that the company calls “Silent Guardian.”

Although Colonel Hymes said the Raytheon product “is not ready yet,” company representatives say it is.

Mike Booen, Raytheon’s vice president for directed energy programs, said the company has produced one system that’s immediately available.
“We have the capacity to build additional systems as needed,” he said.

Raytheon has not sold any Silent Guardians to American or foreign customers, and Mr. Booen would not discuss the product’s price.

American commanders in Iraq already have asked to buy Raytheon’s device.

A Dec. 1, 2006, urgent request signed by Marine Corps Major General Robert Neller sought eight Silent Guardians.

General Neller, then the deputy commander of the 1st Marine Expeditionary Force in Iraq, called the lack of such a non-lethal weapon a “chronic deficiency” that “will continue to harm” efforts to resolve showdowns with as little firepower as possible.

Other requests from officers in Iraq asked for the system as part of a broader weapons package on wheels, one that could shoot bullets as well as the non-lethal beam.

Such a versatile system would let troops deal with “increasingly complex operational environments where combatants are routinely intermixed with noncombatants,” Army Brigadier General James Huggins said in an April 2005 memo to Pentagon officials.

General Huggins, then chief of staff of the Multi-National Force in Iraq and now deputy commander of the 3rd Infantry Division, wanted 14 vehicles for missions ranging from raids to convoy escorts.

American Central Command, which oversees military operations in Iraq from its base in Tampa, Fla., backed the request, saying it was “critical to build upon our success in the counterinsurgency battle,” according to its memo to the Pentagon.

The vehicles were not delivered, however. Robert Buhrkuhl, a senior Pentagon acquisition official, said during congressional testimony in January that combining the various fixtures on a single vehicle presented major technical challenges.

In an interview, Franz Gayl, who was General Neller’s science adviser until the unit returned in February, blamed an entrenched, “risk-averse” military acquisition system for moving too slowly.

Mr. Gayl calls the system a “disruptive innovation” – an unconventional piece of equipment that breaks new ground and therefore is viewed skeptically by the offices that buy combat gear.

If the energy-beam weapon had been fielded when American forces invaded Iraq, “many innocent Iraqi lives would have been spared,” Gayl said.
