As Marines Move In, Taliban Fight a Shadowy War

KARARDAR, Afghanistan — The Marine infantry company, accompanied by a squad of Afghan soldiers, set out long before dawn. It walked silently through the dark fields with plans of arriving at a group of mud-walled compounds in Helmand Province at sunrise.

The company had received intelligence reports that 40 to 50 Taliban fighters had moved into this village a few days before, and the battalion had set a cordon around it. The Marines hoped to surprise any insurgents within.

But as the company moved, shepherds whistled in the darkness, passing warning of the Americans’ approach. Dogs barked themselves hoarse. The din rose in every direction, enveloping the column in noise. And then, as the Marines became visible in the bluish twilight, a minivan rumbled out of one compound. Its driver steered ahead of the company, honking the van’s horn, spreading the alarm. Spotters appeared on roofs.

Marine operations like this one in mid-January, along with interviews with dozens of Marines, reveal the insurgents’ evolving means of waging an Afghan brand of war, even as more American troops arrive.

...

On the morning of the sweep, made by Weapons Company, Third Battalion, First Marines, a large communications antenna that rose from one compound vanished before the Marines could reach it. The man inside insisted that he had seen nothing. And when the Marines moved within the compounds’ walls, people in nearby houses released white pigeons, revealing the Americans’ locations to anyone watching from afar.

The Taliban and their supporters use other signals besides car horns and pigeons, including kites flown near American movements and dense puffs of smoke released from chimneys near where a unit patrols.

“You’ll go to one place, and for some reason there will be a big plume of smoke ahead of you,” said Capt. Paul D. Stubbs, the Weapons Company commander. “As you go to the next place, there will be another.”
