Plot hole: They only take out the shrapnel from the gut shot - they never deal with the shrapnel in his shoulder at all. (00:04:25 - 00:05:00)
Factual error: This series uses a beautifully-rendered CGI sequence of New Amsterdam C. 1650 morphing into New York City of the present day. The Native American tribe we see at the start of the sequence, however, never inhabited the New England area. They look more like the Lakota plains tribes seen in Dances With Wolves. The North-Eastern tribes didn't build teepees as seen here, either. The dwellings should be longhouse wigwams made of wood.

Continuity mistake: When Fast Eddie jumps over the road block and comes crashing down you can see from the severity of the landing that the front left side of the vehicle is seriously damaged as is probably the rest of the front of the vehicle.

He is then flat on his back, staring upwards. Moments later, when the Swedish border guards pull back the rug to look at the corpse, he is face down. No one touched him, and the sled did not bump enough to roll the body completely over.
Continuity mistake: During the street scenes it appears to be fall with leaves on the ground, grass green and streets and sidewalks dry. However, when police raid the park worker's house there is snow on the house roof and on the ground. When the police stake out the same house, there is no snow on the house roof or ground.

Survival, Evasion, Resistance and Escape not really POW. Second: Not all, not even most, NIOs attend SERE school, just some.
