[@Sep] Fair enough. I just saw it as:

*Rex shooting and missing every shot horribly*

"I CAN'T SEE A THING IN THIS!"

*Throws helmet on floor and now shoots perfectly*

I thought they were implying that a Stormtroopers ability to shoot straight is hindered by their helmet. Also, on Hoth, I don't think we saw a single Stormtrooper shoot anyone. I mean, the AT-AT's were tearing hell through everything, but the Stormtroopers did bugger all in any of the scenes from episode 5. And on Endor, the only Stormtrooper that got a hit was that one that shot Leia in the arm, the rest were missing the Ewoks horribly, except those in the AT-ST's, but you don't really need to be that accurate with a heavy laser cannon. I'll give you the other's, though.
