Major Jason Dempsey, the No. 3 officer in the U.S. battalion on the border, rides a Chinook out to Kunar Valley, near the Pakistan-Afghanistan border, as troops set out to locate sites that insurgents use as launching points to fire rockets at U.S. bases in the valley. The arrival of 800 troops from the Army's 10th Mountain Division in February marked the first large-scale U.S. presence on the border since the invasion in late 2001.

Major Jason Dempsey relaxes under a make-shift awning on a scorching-hot day near the ridge bordering Pakistan and Afghanistan. U.S. officials said Pakistanis have been angry that the Afghans are building a new fort on the ridge line between the two countries. Pakistan has long suspected that Afghanistan wants to grab tribal lands on its side of the border.

Walking a short distance from the Pakistan camp at Karir Pass, U.S. Marines carry glass mugs and a container of tea to drink along on a mountaintop near the Pakistan-Afghanistan border. To break through the suspicion between Pakistanis and Afghans, troops planned to hold a series of meetings with their Pakistani counterparts. However, they quickly realized that the rugged terrain, poor Afghan roads and a shortage of U.S. helicopters made frequent visits impossible.

On radio guard, Spc. Jeffrey Sutherland, 21, of Greenville, Ohio, checks in with his team. Every few weeks, a team of U.S. and Afghan soldiers fly up to the border area to kick over the Taliban rocket-launch sites and blow up Taliban safe houses, used to store weapons and food.

U.S. Army Spc. Adam Rowe, 29, of Philadelphia, reads a few pages of "The Westies" while on radio watch. U.S. commanders have been able to slow the flow of Taliban fighters across the 90-mile stretch of border by winning over Afghans who live in the Konar River valley, which the insurgents must traverse as they move deeper into Afghanistan.

As morning breaks, U.S. Army Pathfinders prepare to leave their mountaintop camp where they spent the night. To stop the influx of Taliban fighters into Afghanistan entirely, U.S. officials said, they must have the support of the deeply suspicious Pakistani forces, as well as Afghans in the Konar River valley.
