Visible crew/equipment: As the S.E.A.L.s retreat down the mountain, the camera crew is visible at rear, bottom right. Red optical mount and clean-face cameraman are a dead giveaway. (01:08:00)
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.
Audio problem: When the SEALs in the Chinooks take fire, a helicopter crew member fires their weapons. The weapon is a M240 7.62mm Machine Gun, but the audio of it firing is that of an M134 Minigun.
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.
