"Warfare": Recreating an Iraq War firefight in real-time

A brotherhood of young warriors ... Navy SEALs pumping themselves up for battle, armed to the teeth and trained to perfection. Then, it all goes wrong – the beginning of an agonizingly tense, bloody and chaotic reenactment of a real firefight that took place almost two decades ago in Iraq.

Former Navy SEAL Tay Mendoza was actually there. He wrote and directed (along with Alex Garland) the movie "Warfare," out this week.

Garland said, "We had one rule, one rule above all other rules, which was nobody who wasn't there – which, of course, included me – was allowed to introduce anything into the story. The source of all information could only be either Ray or other people that were there."
