On the night of April 26, 2008, UH-60 Black Hawks delivered U.S. Army Rangers to a grassy field in rural Iraq. As the soldiers took up their positions beneath the ascending helicopters, a heavy barrage of small-arms fire began whipping in through the tall grass. The men of Company A, 2nd Battalion, 75th Ranger Regiment had arrived on a mission to find and eliminate an al Qaeda cell. Now they were being ambushed by a group of insurgents less than 50 meters away.
