Examining the tail rotor on a UH-60 Blackhawk helicopter

Chief Warrant Officer Richard Burger, a pilot with the Wyoming National Guard's Company C, 5th Battalion, 159th Aviation Regiment, examines the tail rotor on a UH-60 Blackhawk helicopter during the daily run up checks at Forward Operating Base Salerno in Khost province, Afghanistan, Feb. 26. Burger, a Fort Collins, Colo., native, whose unit is responsible for medical evacuation support in a belt of land across southeastern Afghanistan that covers two and a half provinces, must navigate the difficult Afghan terrain as quickly as conditions will allow.
