Character mistake: When Murphy calls his command, a Marine Staff Sergeant answers the phone as "Sergeant." Maybe in the Army, but a Marine Staff Sergeant would never refer to himself as Sergeant.
Lone Survivor (2013)
1 character mistake - chronological order
Directed by: Peter Berg
Starring: Mark Wahlberg, Ben Foster, Emile Hirsch, Taylor Kitsch
Continuity mistake: At the airbase when Mike is walking from his room into Marcus' to show him the horses on his laptop he's carrying a banana, however in the room he has an apple in his hand. (00:09:00 - 00:10:00)
Shane Patton: Anything in life worth doing is worth overdoing. Moderation is for cowards.
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.
