Factual error: When the seals are tumbling down the mountain one of them almost lands on a rattlesnake. There are no rattlesnakes native to Afghanistan or any other part of Asia. They occur only in the western hemisphere.

Marcus Luttrell: If I don't go home, you don't go home.
Trivia: The real Marcus Luttrell appears several times throughout the movie: he spills the coffee and tells the new guy to clean it up; he's in the operation briefing and shakes his head at the rules of engagement being read; and he's on board the Chinook helicopter when it is shot down.
Answer: The exact quote was "there's no medicine in a gunfight," meaning the SEALs couldn't just stop shooting at the enemy to help another SEAL who was injured. They're speaking more broadly of the "Self-aid" concept, where each person needs to look out for himself until someone else can come provide medical assistance.
Excellent answer.
