Deliberate mistake: The Seal takes a shot with his suppressed pistol through a circular window in the hull of the ship at a hostage taker holding a hostage. When he fires through the glass it never breaks or shatters. Makes no sense how the bullet even passed through. In addition, windows in ships are really thick; it would've taken a few shots to get through and to neutralize the hostage taker. (00:33:30 - 00:34:30)
Deliberate mistake: This episode takes place in the country of Sudan on the continent of Africa. The Seals go to save some teachers at the American school. The school has concrete wheelchair ramps, asphalt paving, concrete curbs, metal railings. No school in Sudan has such architecture, especially asphalt pavement, its dirt, the asphalt would melt. There is also an empty real estate post used for advertisement in the ground. Majority have roofs made of metal, not briquettes. (00:16:00 - 00:17:45)
Containment - S1-E11
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)
Never Get Out of the Boat - S1-E16
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)
Kill or Cure - S3-E9
Deliberate mistake: In a previous episode the Seals conducted a vehicle interdiction snatch and grab because the HVT they were pursuing was said to have lived in an apartment building with a lot of security, cameras, doorman, etc. Part of the team in Mexico now goes to the HVT's two story house to find her dead. What happened to the building she was residing in? (00:11:00 - 00:12:00)
Answer: They should be wearing balaclavas. They do such operations usually on foreign soil.
