How did the Nazis distinguish Jews from their other POWs?

by OwnagePwnage123

In a scene (https://youtu.be/YGPtW6dU5vw) in Call of Duty WW2, a Nazi soldier interrogates a (Jewish) soldier and asks him if they have any Jews, after he refuses to answer, he kicks him before putting them on a train to a labor camp. How accurate to Nazi procedure is this scene?

More of course can be said, but that part of the game was addressed in our AMA by several panelists, especially /u/commiespaceinvader and /u/nate077.
