Drawing on unprecedented access to US special forces, Legion of Brothers explores the nature and impact of nearly 15 years of constant combat since 2001 by focusing on the original foot soldiers in the war on terror: the small teams of Green Berets sent on secret missions into Afghanistan immediately after 9/11 to overthrow the Taliban. Their story is both an epic, untold war story set on a grand canvas - and a tragic, cautionary tale about the origins of America’s never-ending war.
