In this file photo, a member of the Afghan air force sprays down the side of an AAF Mi-17 helicopter at Kabul International Airport, Kabul Afghanistan, August 11, 2011. Three Mi-17 helicopters were transferred March 18 to the detachment at Forward Operating Base Fenty located in Jalalabad, Afghanistan. The receipt of the new aircraft marks the transition from a ‘defend the base’ to a ‘defend the region’ mentality for the Afghan air force detachment members (U.S. Air Force photo by Staff Sergeant Matthew Smith)
