Legion of Brothers

Immediately after the September 11 attacks, the United States government initiated a secret war in Afghanistan. Fewer than a hundred Special Forces soldiers, building a coalition with the rebels of the Northern Alliance, faced off against the Taliban and succeeded in driving them out of power by the end of the year - with minimal coalition casualties and without conventional, large-scale military operations. Despite this victory, the U.S. and its allies soon became mired in a seemingly never-ending war. (Sundance Film Festival)
