 A single shot hit the Iraqi in the chest and killed him instantly. It had been fired from a range of more than three-quarters of a mile, well beyond the capacity of the powerful loophole site, accurate to 3,300 feet. I believe it is the longest confirmed kill in Iraq with a 7.62-millimeter rifle, said Sergeant Gilliland, who was 28 at the time, who hunted squirrels in Double Springs, Alabama from the age of five before progressing to deer and then to insurgents and terrorists.
