A riveting account of Task Force Catamount, the U.S. Army unit that carried out the longest combat deployment of the Afghan War. The task force endured 485 days of continuous combat and fought 565 enemy engagements across some of the harshest terrain on Earth. Task Force Catamount was forged through a unique Army initiative that kept soldiers together from basic training through deployment-a structure that created exceptional battlefield cohesion but left many deeply vulnerable after returning home. Since their return, more Catamount soldiers have died by suicide than were lost in combat. More than a study of tactics and operations, it explores how the same bonds that made the unit effective in war may have intensified the emotional and psychological burdens carried into civilian life. The book also exposes strategic consequences largely absent from public discourse. It documents the largest Taliban incursion of the war, an assault supported by elements of the Pakistani military that Task Force Catamount repelled in January 2007. The aftermath triggered a direct confrontation between U.S. Vice President Dick Cheney and Pakistani President Pervez Musharraf, an episode long overshadowed by media focus on Iraq that reveals the complex alliances shaping the Afghan conflict. Related by the unit's commander Colonel Chris Toner (ret.) this is a rare, unfiltered account of modern warfare, drawn from his personal journals, soldier interviews, classified briefings, duty logs, and thousands of pages of official records. As the U.S. withdrawal from Afghanistan continues to be scrutinized, this account serves as both a frontline tribute to American service members and a critical examination of the human cost of political failure and policy miscalculation. It stands as the first comprehensive narrative of a single task force's deployment during the height of the Taliban resurgence, combining ground-level reporting with strategic insight and emotional weight.
