Scout trooper

"Hmm...what's that big brown thing coming right up to me...looks like a tree...hmm, should I get out of the way or AAAAAAARGH!"

- A scout trooper before crashing into a tree on Endor

Scout troopers were versions of stormtroopers that looked cool but were completely blind, as evidenced by their tendency to crash into anything in front of them. They also got PWNed by Ewoks.
