U.S. Spending Billions to Stop Iraq IEDs By CHARLES J. HANLEY,

The United States is pouring billions more dollars and fresh platoons
of experts into its campaign to "defeat IEDs," the roadside bombs
President Bush describes as threat No. 1 to Iraq's future.

The American military even plans to build special, more defensible
highways here, in its frustrating standoff with the makeshift munitions
- "improvised explosive devices" - that Iraqi insurgents field by
the hundreds to hobble U.S. road movements in the 3-year-old conflict.

Out on those risky roads, and back at the Pentagon, few believe that
even the most advanced technology will eliminate the threat.

"As we've improved our armor, the enemy's improved his IEDs. They're
bigger, and with better detonating mechanisms," said Maj. Randall
Simmons, whose Georgia National Guard unit escorts convoys in western
Iraq that are regularly rocked, damaged and delayed by roadside blasts.

Lt. Col. Bill Adamson, operations chief for the anti-IED campaign, was
realistic about the challenge in a Pentagon interview. "They adapt more
quickly than we procure technology," he said of the insurgents.

Casualty charts show a growing problem.

Better armor and tactics lowered the casualty rate per IED attack last
year. But attacks almost doubled from 2004, to 10,593, meaning the U.S.
death toll from IEDs still rose. Since mid-2005, an average of about 40
Americans a month have been killed by improvised explosives, twice the
rate of the previous 12 months, according to icasualties.org, an
independent Web site that tracks casualties in Iraq.

Meanwhile, the overall U.S. death rate held steady from 2004 to 2005,
making IED fatalities comparatively more significant. Last month, for
example, 36 of 55 American military personnel killed in Iraq were IED
victims.

The bomb makers have the White House's attention. In a radio address on
Saturday, Bush said roadside bombs "are now the principal threat to our
troops and to the future of a free Iraq."

Bush said in a speech Monday that Iran had supplied IED components to
Iraqi groups, but U.S. officials have presented no evidence to support
that, nor did Bush explain why Shiite Muslim Iran would aid Iraq's
Sunni-dominated insurgency.

For their IEDs, Iraqi insurgents, who are believed under the direction
of former military and intelligence officers, rely on the tons of
military ordnance left over from the era of Saddam Hussein, and on
store-bought electronic and other items for ignition systems.

The Pentagon's upgraded Joint IED Defeat Organization is getting a
sharply increased $3.3 billion this year to foil the often rudimentary
weapons, which the Iraqi resistance generally fashions from artillery
and mortar rounds. The "JIEDDO" staff of explosives experts and others
will almost triple, to 365.

From 2004 to 2006, some $6.1 billion will have been spent on the U.S.
effort - comparable, in equivalent dollars, to the cost of the
Manhattan Project installation that produced plutonium for World War
II's atom bombs.

The investment has paid dividends in Iraq: in "jammers" installed on
hundreds of U.S. vehicles to block radio detonation signals; in
massively armored Buffalo vehicles whose mechanical arms disable
roadside bombs. Forty-five percent of emplaced bombs are cleared before
detonation, the U.S. command says.

In one initiative showing how seriously it takes the threat, the
Defense Department proposes spending $167 million to build new supply
roads in Iraq that bypass urban centers where convoys are exposed to
IEDs.

But experts like the Air Force's Bob Sisk, an explosives-disposal
specialist whose teams are daily disarming IEDs north of Baghdad, said
the most important investment is in intelligence.

"The idea is to get the pieces of an IED to `Sexy,'" said this senior
master sergeant.

"Sexy" is CEXC, the Counter Explosive Exploitation Cell, a secretive
group at Baghdad's Camp Victory that is building a database on IED
incidents, in search of patterns and defenses.

"The initiation system" - detonators - "is always of interest,"
Sisk said. The bomb makers have progressed from using washing-machine
timers and pressure switches for initiating explosions, to cell phone
and walkie-talkie signals, and even infrared beams.

The IED analysts are vitally interested in placement-concealment
tactics. The bombs can be found in roadside garbage bags or sandbags,
in piles of rocks, buried in holes, in sheep or dog carcasses. One was
recently discovered disguised as concrete street-side curbing.

Hoaxes are a peril. "The enemy's very smart," said Capt. Peter Weld,
Sisk's commander. "They plant a harmless device that soldiers find and
gather around, and then they hit them with a real device nearby."

"Shaped charges" are also proliferating - killer explosives that
direct armor-piercing projectiles into U.S. vehicles.

The Pentagon's Adamson said new ways to neutralize IEDs on the ground
are critically important. But "we'll never keep up with the enemy's
agility," and the top priority must be "taking down the human component
- the financiers, the suppliers, the bomb makers."

For that, he said, "our goal is to get better technical and forensic
data off the ordnance" - from digital photos, measurements, explosive
residue, fingerprints, debriefings of troops on the scene.

The U.S. command claims significant success, saying it has captured or
killed 41 bomb makers since November. But soldiers still face the bombs
at seemingly the same rate.

The Georgia National Guard's Sgt. Robert Lewis couldn't help being
impressed while on duty in central Iraq.

"There's a road we called IED Alley that the ordnance disposal guys
would clear regularly," Lewis, 47, of Carrollton, Ga., said at his
current post in western Iraq. "But no sooner would they reach the end
of that stretch" - eight miles - "than the insurgents would be
planting IEDs again at the beginning."
