ANBAR PROVINCE, IRAQ - The Humvee slammed to a halt on the desert road between Fallujah and the town of Al Farris. I peered around the driver's head from the back seat and tried to figure out what was happening.

"Why are we stopping?" I said.

I swallowed and took the lens cap off my camera.

"Sure," Sergeant Guerrero said. "You can get out."
