Factual error: The briefer on the oil platform mission says the platform is 12 stories, and 80 million square feet. Doing the math, that makes it half a mile per side if completely square. It is nowhere near that size as shown. The largest oil rig in the world - Berkut in Russia's Far East - has a combined deck area of only 342,000 square feet. (00:13:35)toroscan
Continuity mistake: Six people jump out of a C-17 and Blackburn and Mandy are aboard the aircraft. The next shot shows the SEAL team in the air with parachutes. Then the scene goes to an air base in Incirlik, Turkey. Blackburn and Mandy are there. How did that airplane get from 200 miles inside Syria to a Turkish airbase before the SEAL team even hit the ground? (00:17:00)toroscan
Factual error: A CH-47D Chinook helicopter is shown on the tarmac with N160BE in large white letters. This is a civilian registration number, not one for a military aircraft. A check with the FAA shows it is registered to Unical Aviation at City of Industry, California. (00:26:00)toroscan
Continuity mistake: The team and the hostages escape from the compound in an SUV and a school bus with the SUV in the lead. They are being pursued by a small truck with a mounted machine gun which starts firing on the school bus. They switch positions, moving the SUV behind the bus so that they can protect the hostages and return fire. The next shot in the command post via a drone shows the original lineup, with the school bus behind the SUV.bnemirow
Character mistake: At the start of the episode when Clay is done brushing his teeth and standing in front of the mirror without a shirt, he has no tattoos. He has been seen several times with tattoos on his arms that are not even covered by a normal T-shirt. (00:05:02 - 00:05:23)
Factual error: When Blackburn tells Jason that something has happened with Echo team he is being summoned to the conference room and called a Lieutenant. Blackburn is a Lieutenant Commander and should not be called a Lieutenant. Lieutenant Commanders can be called just Commander but not a lieutenant. Calling him a Lieutenant would never happen in real life. (00:05:54)
Revealing mistake: Supposedly in Liberia, the team takeoff in a helicopter. However, when they take off, the camera reveals the airfield, where several general aviation aircraft are parked. This is highly unlikely to be in Liberia, also the night lights seem to be somewhere in Cali (perhaps LA)). (00:27:20)
Factual error: For some reason in the first several episodes of the second season, a burst of red mist is added whenever an enemy is shot by the SEALs. The human body does not produce a mist of blood when hit by a projectile.
