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)
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)
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)
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)
Factual error: In this episode the Seals are flying around on the stealth helicopters like the ones used on Operation Neptune Spear (Bin Laden op), but for some reason the Seals are using the outdated night vision goggles with 80 degree field of view and not the GPVG-18's with a 97 degree field of view. DEVGRU use the best gear, they would not be using AN-PVS-15 or 31's. On operation Neptune Spear they utilized the GPNG-18's. (00:25:00 - 00:31:10)
Factual error: The Seals are in the briefing room and the speaker says their next target is "supplying the Taliban with the .50 cal armor piercing sniper rifles." Sniper rifles and rifles in and of themselves are not armor piercing, the only thing that is armor piercing is the type of ammunition that can be used in said rifles. Any high power rifle can have armor pricing ammunition made for it such as 7.62 Nato aka .308, .30-06, .338 Lapua Magnum, .50 BMG. A sniper rifle can use full metal jacket ammo too. (00:07:30 - 00:08:00)
Factual error: Lt Commander Blackburn is a navy guy; Lt Commander is a rank only in the Navy, while in the other armed force the same rank is called Major. However, in most of the action he is wearing a US Army uniform.
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)
