The Unforgiving Minute: A Soldier's Education by Craig M. Mullaney

One haunting afternoon on Losano Ridge in Afghanistan, US Army Captain Craig Mullaney and his infantry platoon were caught in a deadly battle with Al-Qaeda fighters when a message came over the radio - one of his soldiers had been killed by the enemy. Mullaney's education - the four years he spent at West Point, the harrowing test of Ranger School and his experience as a Rhodes scholar at Oxford - left him ready to be a combat leader, but despite his preparation he still had to come to terms with what it really means to be a man.
