Capt. Hardenberg: The German army is invincible because it is an army that obeys orders. Any order. No matter how distasteful. It has no sentimentalists, no moralists, no individualists. You will have no future in it if you don't understand that. You may have no future at all if you oppose it. I trouble to tell you this because you have a fine record. You will be a creative soldier, once you get all this "thinking" knocked out of you.
