There's not a lot about the whole battle makes any sense. For starters, where's the air cover? You gotta have air superiority before you send in the ground pounders.... A few Tie fighters would have knocked all those pesky speeders down in no time, and some Tie bombers could have knocked out all the turrets/ground defenses, etc...

It´s funny because in the original X-Wing game, which cutscenes were in part movie stills with some animation added, the advance of AT-ATs on a rebel base does include some Assault Gunboats providing air support (and in a moment those particular fighters have not been introduced in the game storyline yet...).

And the space blockade. Did it actually stop anybody from escaping? Again, where were the fighters? Tractor beams? Anything? What a bunch of clowns.

Well, the novel states some rebel ships were taken down...
