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: 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. (00:32:12 - 00:33:00)
Deliberate mistake: The Seal team is dispatched to an uninhabited island in the South China sea called Panatag Shoal. In the operations room the team is briefed that there is dense jungle. When the team gets there they're walking on paths laden with dry palm trees and paths 15ft wide. Dense jungle means you're walking through thick brush and using a machete to cut it. In reality Panatag Shoal has very little vegetation - it's a natural submerged bank which is covered by sand and rises from the bed of a body of water. (00:30:20 - 00:31:27)
Factual error: Clay is in a van, and he's looking at some men possibly standing guard. He uses his Eotech EXPS optic to zoom in on them. An Eotech optic is a zero power magnification optic, so looking through it is like looking through nothing. The only way it can be magnified is by adding a G33 3x or the newer G45 5x magnifier to the system. These magnifiers flip 90° and lock in place when magnification is needed or flip back when its not. Clay's rifle does not have a magnifier. (00:14:00 - 00:15:00)
Deliberate mistake: Sunny is the teams SAW (squad automatic weapon) gunner. He carries an FN MK46 which is a special operations version of the M249 SAW. The MK46 unlike the M249 only takes belt-fed ammunition from 100 or 200 round "nutsacks." On this mission Sunny is wearing a chest rig with STANAG mags and no nutsacks. He has no backpack for extra ammo either. He hands off his MK46 to the Jason whose staying behind and no nutsacks. Plus he doesn't take Jay's HK416 rifle in the swap. Usually people swap one for one. (00:31:15 - 00:32:00)
Continuity mistake: Jason and his team have AKS-74U's in hand as they hit the target vehicles. Once their target escapes they start giving chase and their weapons disappear from their hands and as they're running no holster are visible with sidearms. Then once they reach the inside of a building they all have pistols in hand. Even if the sidearms were "hollywood tucked" into their pants they would've fallen out during their chase of the target. Plus military guys all use holsters. (00:33:42 - 00:35:00)
Other mistake: Ray and Clay are utilizing sniper rifles to combat the hostile enemy. Their shots are both shown through a thermal optic view, however both of their rifles only have standard day optics. For a thermal view to be operational a separate thermal optic needs to be clipped on to the front of the day scope/optic to provide a thermal view. A day scope/optic doesn't magically become thermal. They mount onto the top rail of the Picatinny Rail. (00:29:00 - 00:29:40)
