The Green Berets were, in their own words, “America’s response to the most catastrophic terrorist attack on U.S. soil ever.” Sent to Afghanistan in the wake of Sept. 11, the Army Special Forces crew is now the subject of a documentary called “Legion of Brothers.” The Huffington Post has the exclusive trailer.

Dispatched on top-secret anti-Taliban missions, the Green Berets recount their harrowing mission. “We’re just trying to live,” one says, reflecting on the intensity.

Despite tactical errors and the lingering stresses of warfare, the soldiers’ early initiatives were successful enough to convince them Islamic terrorism was being curtailed for good. Sixteen year later, we see the toll the war in Afghanistan took on these men’s lives. Director Greg Barker, who has experience with the subject via his 2014 doc “Manhunt: The Inside Story of the Hunt for Bin Laden,” presents “Legion of Brothers” as a nonpartisan story about the human toils of combat.

“Brothers” open in select theaters May 19 and premieres on VOD platforms June 26. Watch the trailer above.
