Soldier quote about battle from "Band of Brothers"

Ronald Spiers: You've got some nervous privates in your company.

Pvt. Albert Blithe: We do, sir. We do.

Ronald Spiers: They just don't see how simple it is.

Pvt. Albert Blithe: Simple, what is, sir?

Ronald Spiers: You just do what you have to do.

Pvt. Albert Blithe: Like you did on D-day, sir? Lieutenant, sir, when I landed on D-day, I found myself on a ditch all by myself. I fell asleep. I think it was airsickness. When I woke up, I didn't really try to find my unit to fight. I just kinda stayed put.

Ronald Spiers: You know why you hid in that ditch, Blithe?

Pvt. Albert Blithe: Scared.

Ronald Spiers: We're all scared. You hid in that ditch because you think there's still hope. But Blithe, the only hope you have is to accept the fact that you're already dead. And 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.
