And that the guy who plays Dak (Luke's gunner in ESB) is also the same person that play's this guy in the Imperial walker that is trying to blow up himself...apparently
(I have a hard time believing the last one, but it says so in my Behind the Magic CD-Rom. Dak looks way younger than the officer in the walker. Maybe it was Janson. I donno. But what I do know for a fact is that the Imperial walker commander dude is also one of the gunners in the snowspeeders.)
And that it is none other than Mark Hamill himself that says "The first transport is away! The first transport is away!"
General Veers and Dak are different actors you can check here http://www.imdb.com/title/tt0080684/fullcredits
