Also, is it stated in the movies (OT) that the Empire is drafting people? I kinda figured it was indoctrination and the lure of the darkside.
BIGGS: I know it’s a long shot, but if I don’t find them I’ll do what I can on my own… It’s what we always talked about. Luke, I’m not going to wait for the Empire to draft me into service. The Rebellion is spreading and I want to be on the right side – the side I believe in.
LUKE: Well, I’ll be at the Academy next season… after that who knows. I won’t be drafted into the Imperial Starfleet that’s for sure… Take care of yourself, you’ll always be the best friend I’ve got.
As an aside, this convo with Luke completely dispels the EU misconception that Luke was joining an Imperial Academy. Why would Biggs and Luke be worried about being drafted into the Empire if they were already signing up? On the contrary, it points to the Academy either being part of a local municipality or the equivalent of a trucker school. Just one of those things that the EU got wrong that has always bugged me.
