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)
Character mistake: When Jason is having his toast in the bar, he begins listing up the amount of decorations there are in the room, starting with saying there are three Silver Star medals in the room. Bravo Team alone has eight Silver Star medals. The only operators from Bravo who do not have the Silver Star medal are Blackburn and Full Metal. Full Metal was a real SEAL before going into acting, and earned a Navy Cross that he also wears in the show on his dress uniform. (00:36:36 - 00:37:12)
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.
