Factual error: The repairman was freeing the soldiers from inside the locked gate using bolt cutters. The terrorist noticed this on the video feed so they electrified the fence, shocking the repairman. This would not have happened because the bolt cutters have plastic handles just for that reason, to keep you from being electrocuted by mistake. (00:54:50)
Character mistake: During the opening raid of the FSB safe house, an operator is seen taking hard drives out of a safe.

Other mistake: When the detective sends the traffic cam footage, a Gmail alert pops up. However, the dad is currently using Margot's computer, not his. He previously logged into Margot's gmail account on this computer so any alerts received would be Margot's mail, not his.
Revealing mistake: During the police chase with Gabriel on his motorcycle, he stops and turns to start shooting at one of the cops. By appearances, Gabriel is using a standard Glock which had a magazine capacity of 15 rounds. He has no extensions on it at all with the handle and magazine visible.

A few minutes later, when Thomas is kneeling over Newt, after Newt stabs himself in the chest, the stab hole in Thomas' shirt is no longer there and he isn't bleeding. (01:50:45)
Plot hole: Kingsley holds the only key card that can access the control room where the Captain is. He only has one card. He gives this key card to Rhodes so he can go up there and talk the Captain into not taking the sub to the surface yet, while Kingsley and his men head down to stop Scott and Taylor. When they employ the help of Marco and take out Kingsley and his men, Marco bends down and pulls the key card off Kingsley's neck so that now they have it... only Kingsley didn't have the key any more, as Rhodes had it and was still in the control room. A second key card magically materialized on Kingsley's neck.
