From the earliest days of his 34-year military career, Victor "Brute" Krulak displayed a remarkable facility for applying creative ways of fighting to the Marine Corps. He went on daring spy missions, was badly wounded, pioneered the use of amphibious vehicles, and masterminded the invasion of Okinawa. In Korea, he was a combat hero and invented the use of helicopters in warfare.

From the former secretary of defense, a strikingly candid, vivid account of serving Presidents George W. Bush and Barack Obama during the wars in Iraq and Afghanistan. When Robert M. Gates received a call from the White House, he thought he'd long left Washington politics behind: After working for six presidents in both the CIA and the National Security Council, he was happily serving as president of Texas A&M University. But when he was asked to help a nation mired in two wars and to aid the troops doing the fighting, he answered what he felt was the call of duty.

Raw, straightforward, and powerful, Ed Kugler's account of his two years as a Marine scout-sniper in Vietnam vividly captures his experiences there - the good, the bad, and the ugly. After enlisting in the Marines at 17, then being wounded in Santo Domingo during the Dominican crisis, Kugler arrived in Vietnam in early 1966. As a new sniper with the 4th Marines, Kugler picked up bush skills while attached to 3d Force Recon Company, and then joined the grunts.

Like the men whose epic stories Jon Krakauer has told in his previous bestsellers, Pat Tillman was an irrepressible individualist and iconoclast. In May 2002, Tillman walked away from his $3.6 million NFL contract to enlist in the United States Army. He was deeply troubled by 9/11, and he felt a strong moral obligation to join the fight against al-Qaeda and the Taliban. Two years later, he died on a desolate hillside in southeastern Afghanistan.
