Task Force Black by Mark Urban

Soon after British and American forces invaded Iraq they faced an insurgency that was almost impossible to understand, let alone reverse. Facing defeat, the Coalition waged a hidden war within a war. Major-General Stan McChrystal devised a campaign fusing special forces, aircraft, and the latest surveillance technology with the aim of taking down the enemy faster than it could regenerate. Guided by intelligence, a small British special forces team met the car bombers' fire with fire and accounted for thousands of insurgents.
