Military rules of engagement are being closely examined in the wake of accusations that U.S. Marines killed 24 unarmed civilians in the Iraqi town of Haditha.
In the latest in a series of conversations on leadership in a lengthening war, we hear from an enlisted man who wrote about his experiences in Iraq -- and helped change the way Marines are taught to go into urban combat.
Staff Sgt. Earl J. Catagnus Jr. was the leader of a group of snipers who worked to remove insurgents from houses during the battle of Fallujah in November 2004.
