BAGRAM AIR FIELD, Afghanistan -- An Air Force HH-60G Pave Hawk takes off for a medical evacuation mission as the sun sets over Bagram Air Field, Afhanistan, Aug. 16. Although primarily used for combat search and rescue, the Pave Hawk supplements the Army’s UH-60 Black Hawks in medical evacuations during night and marginal weather conditions.
