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)
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)
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.
Audio problem: One of the team members shoots a sentry on board a ship off a ladder attached to the deck hanging off the side of the ships hull. He shoots an unsurpassed Glock and the shot sounds suppressed. A muzzle flash can be seen too, another indicator it's unsuppressed. Their element of surprise would have been totally eliminated had this really happened. They've used suppressors before on their sidearms - doesn't make sense why they wouldn't now. (00:31:00)
Factual error: The team is in the briefing room, and they're being dispatched to Panatag Shoal. The picture of the island in the ops room has been modified from the original. The original real world picture shows very little vegetation. For this series they created a jungle to replace the water and sand shoal to make it fit their mission. The way the island is depicted in the series doesn't exist in reality. (00:30:20 - 00:31:27)
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)
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)
Other mistake: Before the Seals went on their counter-sniper operation they were briefed that the enemy snipers were going to be using SVD-63 Dragunov's which have a range of 800m. The two enemy snipers who were killed never had Dragunov's, they had standard bolt action type rifles without suppressors, hard to identify a specific brand. They engaged the Seals from a distance with unsuppressed weapons over a crowd of people and the crowd didn't hear a thing. This is a falsity, a 7.62mm shot can be heard for 3km. (00:37:26 - 00:38:00)
Factual error: One of the Seals is donning a night vision device, and he looks through his Eotech Exps optic and the dot appears red. That is incorrect a holographic sight or a red dot through night vision appears as a dot, there is no red color through night vision. Soldiers rely on their AN/PEQ-15 ATPIAL laser for targeting when they use night vision. (00:23:30 - 00:24:00)
Factual error: The Seal team is heading up the stairs and a terrorist pokes his head out, and he gets shot 4 times with 5.56 rounds. He's dead, but he manages to exhale a grunt and as he's falling down the middle opening of the stairwell, and he's screening "ahhhhhhhh." This show and many like it have found a need for dead guys to exhale grunts or screams. When somebody is killed their brain shuts down. There's no noise being made by the body unless it's the body itself falling like a sack of potatoes. (00:41:00)
Character mistake: Lindell is referred to as Captain Lindell; however, on his office wall, he has a Meritorious Service Medal Award that references Captain Greyson Lindell, USMC. The fact Lindell is a Marine, he should be recognized as a Colonel and be wearing a USMC uniform, not a U.S. Navy uniform. (00:26:43)
Factual error: When they capture the trucks they first say that there is no nuclear material. But later find that the warheads are nuclear. A Geiger counter would pick up nuclear material from a warhead or a dirty bomb. Also, they are worried about the bombs being unstable. No way are the cores unstable. The conventional explosives could be. Why wouldn't they separate the explosives from the warhead? Finally, wouldn't you scout out the bridge before driving across? There are tons of loose boards.
Factual error: Seals arrange their weapons and gear according to the mission they are deployed on, CQB requires short compact weapons, so they'll go with H&K 416 with a 10.4" barrel or the H&K MP7, for open terrain missions they'll swap out their uppers in the H&K 416's and swap in the 14.5" barrels. Bravo team is on a jungle op where no CQB is expected however most of the guys are rolling with 10.4." Clay is the only one with the long distance set up. Sonny doesn't even have his MK46 SAW.
