The Captain (2017)

Kipinski: Captain... What exactly is the mission?
Willi Herold: To get clarity on the situation behind the front.
Kipinski: I can give you clarity on that. The situation is always what you make of it. Isn't that right, Captain?

Sichner: Under what authority?
Willi Herold: Under what authority? Under the highest authority.
Sichner: The highest authority...
Willi Herold: Under the authority of the Fuhrer himself.

Freytag: Captain! Please!...
Willi Herold: They're already dead. Either way...

Willi Herold: The Fuhrer has given me authority to take all necessary measures whenever German combat forces are at risk. The soldier can die, but the deserter must die.

Willi Herold: Move! Put an end to his unnecessary suffering.
Freytag: ..... Respectfully reporting. Order executed, Captain.

Willi Herold: Yes, that I am. The Captain.

Willi Herold: I am Captain Herold, head of Special Detachment and Express Court Herold, the avenging angel of our sacred German honor! And I will ensure every traitor to the Fatherland gets just punishment. This sentence will please all honor-loving Germans, and be a warning to all cowards who betray their Fatherland in these hard times. I will return law and order to this place.

Dr. Kremer: So you confess to the following crimes: impersonating an officer, organizing the massacre in Camp ll, and, finally, hanging a mayor who was flying a white flag.
Willi Herold: Shooting. Shooting a mayor who was flying a white flag. My father always said, “if you've done something wrong, then at least admit it.”
