The sun was fading behind Afghanistan’s Hindu Kush mountains the evening of June 27, 2005, as a team of four US Navy SEALs walked up the ramp and into the back of US Army Capt. Matt Brady’s MH-47 Chinook helicopter on Bagram Air Base. Tasked with inserting the SEAL special reconnaissance (SR) team deep into enemy territory in unforgiving terrain, Brady knew the SEALs — Lt. Michael Murphy, Petty Officer 2nd Class Danny Dietz, Petty Officer 2nd Class Marcus Luttrell, and Petty Officer 2nd Class Matthew Axelson — had a difficult mission ahead. Marines in the area knew it was an extremely dangerous place filled with Taliban fighters. Brady had no way of knowing at the time, but it would be the last time anyone at Bagram would ever see three of those four Americans alive.
