They sorely needed more scenes of rebel troops fighting, probably less of ewoks fighting. But the things that stick out to me in that bunker scene is it's kinda silly for Han to run up and then just stand there in the open for a bit before the shooting starts. And then having one rebel soldier cross over in front of Han, and Chewbacca crossing over behind. Just doesn't seem how a swat team or whatever would use cover, but has that hokey Hollywood kinda feel to the squad tactics. I know it's not Black Hawk Down or Band of Brothers, but still.
