Obersturmführer Kurt Kotler of the Totenkopf Division
from The Boy in the Striped Pyjamas.
Quite a contradictional character considering that Kotler is a Jewish-German last name. Not much is shown of him in the movie aside from his short temper and failure to report his father who is presumed a traitor. He is later reassigned to the Ostfront for this. In all, his own bit of the story is very shadowed and unexplained. It is left in our own hands to decide what we think of him, even with such a lack of background.
Every soldier has a story, no matter the uniform.
