Four Airmen find home at international base
Staff Sgt. William Cook checks a fuel sample he has collected from an R-22 fuel pumping unit at Chaghcharan Forward-Operating Base, Afghanistan, to make sure it has the proper color, clarity, as well as free of water and particulates. Sergeant Cook is one of four Airmen deployed to Chaghcharan, which is run by the Lithuanian military and conducts International Security and Assistance Force missions from the base.
