I saw an interview with one them (pretty sure it was, anyway) . He was spotting for air strikes and the locals jumped on top of him when the Taliban attacked. He thought he was a goner but they explained that they were protecting him because if he got killed the planes would stop coming. I have to try and find this movie.
The movie is about the first special forces team to be deployed in response to 9/11. I've heard people call them the "Horseback Soldiers".
