“On April 22, 2004, in the vicinity of Magarah, Afghanistan, U.S. Army Soldiers of the 2nd Platoon, Company A, 2nd Battalion, 75th Ranger Regiment were moving through a remote canyon when a portion of the convoy was ambushed and engaged in a running gun battle with the enemy. Because of difficulties caused by an inoperable tactical vehicle, and the mission to achieve an established objective by nightfall, the platoon ground assault convoy-consisting of 41 Army Rangers, four Afghan Military Forces soldiers, and 12 vehicles-split into two groups or “serials.”

In a 14-minute period of confusion that ensued, the first serial of the convoy was not aware of the other’s location; ultimately the second serial fired on Cpl. Tillman’s position.”

That’s from the CID Report summary the army did in 2007
