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.
Factual error: In the scene at the evacuation hospital doctors are seen administering shocks to Marcus Luttrell (Mark Wahlberg) with paddles. The EKG shows a flatline. In reality, medical personnel do not give shocks for a flatline - a "shock" is to correct Ventricular Fibrillation into a normal sinus rhythm, if you have a systole there is no muscle activity in the cardiac area and a manual shock will not achieve anything.
Factual error: In many shots we see a Marc Lee memorial patch. Marc Lee was killed August 2, 2006. Operation Redwing was June 28, 2005, more than a year earlier.
Factual error: During the final attack on the village by Apache helicopters, they are shown with front-mounted machine guns instead of the 30mm cannon. Apaches are not armed with a front machine gun.
Factual error: Throughout the film, the SEALs are seen wearing Mechanix gloves, but the type seen are the current type. What distinguishes them from older models is the velcro wrist strap. The older models had an elastic, velcro strap, while the newer ones have a reinforced, rubberized velcro strap. The newer type as seen in the film is inaccurate for the time period.
Suggested correction: That's not true. If ever you do a first aid course they will point out that on arrival, paramedics will replace your AED with their defib precisely because their defib will shock no pulse, whereas an AED that you might find in public spaces will not.
No professional medical professional would shock a flatline patient. They would start chest compressions until they could determine why the heart stopped. Ventricular Fibrillation or Ventricular Tachycardia, where shocking may help, does not register as a flatline. The mistake is valid and doesn't need to be corrected.
