Let’s put it this way: do you think Vader had “elite” troopers with him in ANH, when he is boarding the Tantive iv? They sure don’t look like it… And that could be considered as an equally important mission.They all did as they were told and they all did what was expected of them. There wasn’t a stormtrooper on board who suddenly thought “naaaaah…I didn’t sign up for this!” and then helped Leia and the Droids escape.

I know it’s EU and not a movie, but this book is all about a highly trained, top of his class Imperial pilot who deserts after the destruction of Alderaan by the Death Star. I’m halfway through and it’s very good.
