Would be hard to pick only 5. Hell, I've already seen more than five from posts in this thread.
More of my favorites:
Arthur's knights riding through the blossoming trees for their final battle in Excalibur
Shugart and Gordon, Black Hawk Down
Courage is not the absence of fear but rather the judgment that something is more important than fear.
The brave may not live forever but the cautious do not live at all.
