Battle of Yavinin the ANH movie/ANH novel
Okay, I've just finished reading the ANH novel, and there is a big difference in the way the Battle of Yavin is described. In the movie, there are only two squadrons, Red and Gold, right? Only X and Y-Wings?
Well, in the novel, I'm sure it says that there are four squadrons, Yellow, Red, Blue, and Green, and that Yellow and Green were cover squads for Red and Gold. There were no cover squads in the movie! Red squadron had to do strike and cover together.
I'm wondering, is this how Lucas originally wanted the Battle to go? Because he wrote the ANH novel.
