Marines On Patrol in Helmand Province

KHAN NESHIN, AFGHANISTAN - MARCH 13: (FRANCE OUT) US Marines with the 4th Light Armored Reconnaissance Battalion pull on a cable to try and get a vehicle unstuck from mud during a mission around Khan Neshin on March 13, 2010 in southern Helmand province, Afghanistan. The terrain around rural Khan Neshin is without paved roads and is notoriously treacherous for the Marines' heavy vehicles, which can get suddenly mired in hard-to-see muddy patches. The Marines at Khan Neshin are the southernmost troops in Afghanistan, using the earthen walls of an ancient Afghan castle as a base to monitor activity in this hotbed of smuggling and insurgency near the southern border of Afghanistan and Pakistan.
