Air Force and Afghan National Army Air Corps servicemembers provide security as members of the nomadic Kuchi tribe are dropped off at a safe location during a humanitarian rescue mission Feb. 8, 2010, in Kandahar, Afghanistan. Their village, located on a sandbar in the middle of a normally otherwise shallow river, was cut off from the mainland as water levels rose approximately 20 feet deep. (U.S. Air Force photo/Capt.
