US struggles to defeat lo-tech weapons
The No 1 killer of Nato troops in Afghanistan is home-made bombs

The world's most powerful military machine is scrambling to fight a simple, lo-tech weapon in Afghanistan that is killing and maiming US and allied soldiers at an alarming rate. The home-made bomb - often a mixture of fertiliser, fuel and metal - is the No 1 killer of Nato troops in Afghanistan, and the US military has launched a massive, costly effort to try to defeat it.
In Iraq, the Americans eventually managed to contain the scourge partly by employing jamming devices and large numbers of unmanned aircraft that could watch for insurgents planting roadside bombs.
But the rudimentary improvised explosive devices (IEDs) in Afghanistan have no radio frequency to jam, while the country's vast, rural landscape makes surveillance a daunting task, US officers say.
"You've got an entirely different challenge in Afghanistan," said Lieutenant General Thomas Metz, head of the Pentagon's Joint Improvised Explosive Device Defeat Organisation. "It looks about like the moon sometimes. It's huge, open spaces. Not much vegetation. It's an unbelievable, tough, rugged terrain."
American soldiers learned to identify suspicious objects on paved streets in Iraq, but Nato forces in Afghanistan had trouble picking out tripwires or booby traps on dirt roads, said Command Master Sergeant Todd Burnett of Metz' organisation, who regularly visits troops on the Afghan front. Soldiers who had only recently arrived in Afghanistan were still trying to figure out how to handle the IED threat there, he said.
"For so long we've been focused on Iraq. We're still learning the environment over there ... we're playing catch-up." And unlike Iraq, where much of the insurgent activity was concentrated in city centres, the bombs were spread over an enormous area, Burnett said.
The threat has steadily mounted in Afghanistan, with more than 1,000 IEDs found or exploded in August - a dramatic increase from just a year ago. But the scale of the threat is still much lower than what US and Iraqi forces faced at the height of violence in Iraq, when the number of IED incidents rose to about 2,500 a month.
Metz, charged with leading the effort against the bombs, said eliminating IEDs was unrealistic, but he talks about the need to get "left of the boom" - by detecting the bomb before it goes off and targeting the bomb-making networks.
His organisation, set up in 2006 to tackle the scourge in Iraq, invested close to US$1 billion over the past year in technology, training and other initiatives to battle the home-made bombs.
Metz said he hoped sensors and software could be refined soon to detect small changes on the ground, revealing where an insurgent may have dug up a road or set down a tripwire.
But he said the "game-changing" technology was still not there.
"We're left with some real tough physics problems," he said, as the sensor had to deliver reliable information quick enough to allow a vehicle speeding down the road to stop before reaching the bomb.
To protect troops, the Pentagon is rushing the production of new armoured vehicles for Afghanistan, as a version designed for Iraq has proved too bulky for the country's treacherous terrain.
Seven of the new M-ATVs (mine-resistant, ambush-protected, all- terrain vehicles) have been delivered and the Pentagon has approved plans to quickly produce more to ship to the war.
Defence Secretary Dr Robert Gates has deployed nearly 3,000 troops trained in explosives disposal, intelligence and route clearance to contain the IED threat.
Commanders are working to shift much of the unmanned-aircraft fleet from Iraq to Afghanistan to spy on insurgents planting bombs, and the US military has bought smaller robots that can help soldiers dismantle explosives in a more rugged setting.
In the meantime, the IEDs are wreaking havoc, killing and badly wounding Western troops and Afghans while piling pressure on the Nato-led mission.
With the carnage from the bombs undermining public support for the war on both sides of the Atlantic, some lawmakers in the US Congress say the military has to move faster.
The Pentagon promised that anti-IED programmes would produce results soon, but the death toll kept rising, Republican congressman Duncan Hunter said at a recent congressional hearing.
"We've been ... told that since I got into office in January, `It's going to be there soon, sir. It's going to be there soon'," Hunter, a marine veteran who served in Iraq, said.
"It isn't there now. And we're losing guys every day. So what are we going to do tomorrow to defeat IEDs so that we don't have any more IED deaths?"
