At 24 years of age, U.S. Army Ranger Sean Parnell was named commander of a forty-man elite infantry platoon - a unit that came to be known as the Outlaws - and was tasked with rooting out Pakistan-based insurgents from a mountain valley along Afghanistan's eastern frontier. Parnell and his men assumed they would be facing a ragtag bunch of civilians, but in May 2006 what started out as a routine patrol through the lower mountains of the Hindu Kush became a brutal ambush.

12 Strong is the dramatic account of a small band of Special Forces soldiers who secretly entered Afghanistan following 9/11 and rode to war on horses against the Taliban. Outnumbered 40 to one, they pursued the enemy army across the mountainous Afghanistan terrain and, after a series of intense battles, captured the city of Mazar-i-Sharif. The bone-weary American soldiers were welcomed as liberators as they rode into the city. Then the action took a wholly unexpected turn.

From the winter of 2006 through the spring of 2007, 250 marines from Echo Company, Second Battalion, Fourth Marine Regiment, fought daily in the dangerous, dense city streets of Ramadi, Iraq, during the Multi-National Forces Surge ordered by President George W. Bush. The marines' mission: to kill or capture anti-Iraqi forces. Their experience: like being in hell. Now Major Scott A. Huesing, the commander who led Echo Company through Ramadi, takes listeners back to the streets of Ramadi in a visceral, gripping portrayal of modern urban combat.

In November 1965, some 450 men of the First Battalion, Seventh Cavalry, under the command of Lt. Col. Hal Moore, were dropped by helicopter into a small clearing in the Ia Drang Valley. They were immediately surrounded by 2,000 North Vietnamese soldiers. Three days later, only two and a half miles away, a sister battalion was chopped to pieces. Together, these actions at the landing zones X-Ray and Albany constituted one of the most savage and significant battles of the Vietnam War. How these men persevered makes a vivid portrait of war at its most inspiring and devastating.

In 2009 Clinton Romesha of Red Platoon and the rest of the Black Knight Troop were preparing to shut down Command Outpost Keating, the most remote and inaccessible in a string of bases built by the US military in Nuristan and Kunar in the hope of preventing Taliban insurgents from moving freely back and forth between Afghanistan and Pakistan. Three years after Keating's construction, the army was finally ready to concede what the men on the ground had known immediately: It was simply too isolated and too dangerous to defend.
