US Army Works in Mountain Bases in Afghanistan

ZEROK, PAKTIKA - OCTOBER 06: An Afghan National Army soldier dashes away from the rotor wash of a US Army Chinook helicopter on October 6, 2009 at Forward Operating Base Zerok in Paktika province, Afghanistan. Conditions are harsh for the soldiers of the 3-509 US Army's 25th Infantry Division and their Afghan Army counterparts at the Zerok field base near the border with Pakistan. The troops stationed at the base frequently patrol the adjacent mountains on foot and endure frequent attacks by militants, as well as living without showers or laundry for months.
