Seen through a haze of fine dust kicked up by the helicopter's rotor blades, US Marines carry a wounded comrade who was hit by an Improvised Explosive Device to a medevac helicopter of U.S. Army's Task Force Lift "Dust Off", Charlie Company 1-171 Aviation Regiment in Helmand province on Nov. 2, 2011. The Marine lost his right leg from the knee in the blast.
