June 28, 2005, was supposed to be a routine day in the Hindu Kush. Well, as routine as any mission in that part of the world at that time could be. It would turn out to be a day we remember 20 years later. 

Four Navy SEALs—Lt. Michael Murphy, Matthew Axelson, Danny Dietz, and Marcus Luttrell were sent to locate a Taliban-aligned warlord named Ahmad Shah. Instead, they walked into a buzzsaw. Compromised by goat herders, outnumbered, and outgunned, the mission spiraled into a bloodbath. Murphy made a satellite call for help while exposed to enemy fire—a move that earned him a posthumous Medal of Honor. Luttrell survived, barely, thanks to a local villager and the ancient code of Pashtunwali. Nineteen Americans died that day, including 16 aboard a Chinook helicopter shot down during the rescue attempt. 

That’s the Reader’s Digest extraordinarily condensed version of events. Chances are, if you are reading this, you are familiar with the story. The lone survivor, Marcus Luttrell, wrote a book about it, and that book was later made into a movie.
