Continuity mistake: When Hayes passes Perry the laptop onboard the plane, the screen shows VLC media player on the screen. When we see Perry, the laptop is showing the desktop. (00:17:00)
Other Lives - S1-E2
Continuity mistake: In the pilot episode the team wore patches showing their unit such as "2A9" however in the second episode they now show "2B9".
Ghosts of Christmas Future - S1-E4
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)
Continuity mistake: Six people are lined up to jump out of a C-17. Two people jump out. In the next shot there are still six people lined up to jump. (00:16:20)
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: In the first scene an armored vehicle is approaching with a small slit for the driver to see. In other scenes the driver has a much bigger window. (00:25:55)
Continuity mistake: Clay usually carries the H&K416 with the 14.5" barrel with the addition of a Surefire suppressor and a variable optic scope, whereas the rest of the team caries the more compact 10.4" barrel with Surefire suppressors and Eotech optics. Sometimes Clay carries the M110 Sniper, all their gear changes up depending on mission. On this mission Clay is with the 14.5" with scope and later when he exits the sub tube he hands the sub crewman a 10.4" with Eoetch. They didn't switch weapons underwater. (00:00:45 - 00:06:00)
Continuity mistake: The Seals are on the edge of the Afghan, Iranian border, it's not raining, it's raining back at the base where the QRF Marines are on standby. When the QRF responds the attack helicopters decimate the enemy there's no clouds, fog or rain, however when the Osprey lands a few seconds later to pick up the Seals the weather is rainy, foggy and cloudy. The scenes were shot on different days. (00:27:30 - 00:34:30)
Rock Bottom - S2-E20
Continuity mistake: The team is somewhere in the Kashmir region and there's a few horses around them which appear to be wild. There is no farmhouse anywhere near them. The Seals end up commandeering the horses, and they're riding them. However, the horses have blankets and saddles on their backs. I'm pretty sure it's difficult to ride a wild horse, and they definitely didn't HAHO in on a mission with leather horse saddles and blankets. In addition, there was no farmhouse for them to find saddles to equip the horses. (00:27:15 - 00:28:30)
Continuity mistake: A taxi is pursuing a Mercedes sedan. At one point they collide - taxi left side and Mercedes right side. Later in the chase, the scrapes and tire marks on the Mercedes are on its left side instead of its right. (00:08:37 - 00:09:39)
Continuity mistake: Jason and the team track the bomber to his mansion and isolate him in his hiding spot. Jason opens the door outward (toward him). In the next scene when the team streams into the room the door is open inward.
All Along the Watchtower: Part 2 - S3-E6
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.
Unbecoming an Officer - S3-E10
Continuity mistake: Jason is in bed with his girlfriend lying on opposite ends of the bed. The girlfriend's feet are exposed. When the camera pans up to her face and back down, she only has one foot exposed. (00:02:00)
Answer: Yes. They would have to land 3-4 times for refuelling. The plane could fly with the wheels down, but the additional drag slows the plane and increases fuel consumption.
