Unreal City - S2-E1
Continuity mistake: While Lieutenant Granderson is being escorted around the compound and walks to the class, she is wearing O-3 rank (two silver bars) on her collar, despite never being promoted during the show to this point. Later on in the episode, when she is talking to her mother, she is wearing O-2 rank (one silver bar) again. (00:13:35 - 00:34:15)

Revealing mistake: When Chandler and the others make it to the building where the bodies are being burned, the actor playing a corpse flips his hand over to hold onto the conveyor belt as he goes over the edge. (00:16:05)
Unreal City - S2-E1
Factual error: In the scene where the crew is taking back the ship, a crewman sticks his head out of a door and right in the middle of the shot is some piping. It looks cool until you realize it is a PVC ball valve. Plastic piping is not used on US warships.
