The actor who portrayed his character in Band of Brothers did an excellent job. The quote was interesting, and chilling the first time I heard it.
"The only hope you have is to accept the fact that you're already dead. The sooner you accept that, the sooner you'll be able to function as a soldier is supposed to function: without mercy, without compassion, without remorse. All war depends upon it."
The ironic part about that is that he lived through WWII.
