The clip The young recruits Part 2 from All Quiet on the Western Front (1930)
Everything you ever learned, forget! See?
Forget what you've been and what you think you're going to be.
You're going to be soldiers, and that's all!
I'll take the mother's milk out of you! I'll make you hard-boiled!
I'll make soldiers out of you or kill you!
Detachment... lie down!
Keep your head down, Baumer!
Detachment... get up!
Do you call that singing?
So... we have no spirit, huh?
We are in no mood for recreation.
Work is what we want. Good!
Then we'll go back to work!
Detachment, lie down!
Keep your head down!
