Marines and Afghan units converged on a dangerous western quarter of the Taliban stronghold of Marjah on Sunday, with NATO forces facing "determined resistance" as their assault on the southern town entered its second week. Fighter jets, drones and attack helicopters hovered overhead, as Marine and Afghan companies moved on a 2-square-mile (5.2-sq. kilometer) area of the town where more than 40 insurgents have apparently holed up. "They are squeezed," said Lt. Col. Brian Christmas, commander of 3rd Battalion, 6th Marine Regiment. "It looks like they want to stay and fight but they can always drop their weapons and slip away. That's the nature of this war."
