There is one addition in the trailer that I find a little bit silly, though. That is that the Echo Base gun turret shoots after the Snowspeeders after they have passed it.
- The gun turret fires very close to where you would extrapolate the snowspeeders to fly.
- The snowspeeders have yet some time to reach the AT-AT walkers. So, the AT-AT's would still be quite far from the gun turret. Right?
