During the battle of Hoth when Luke tosses the Thermal Detonator in the AT-AT, maybe have a shot (2-3 seconds long) of snow troopers sitting in the back lit by a red light (ready to be deployed) and then have the screen fill up with an explosion and then cut to the exterior shot of the AT-AT blowing up and falling down.
I feel that this helps expand the depth of the battle by including an added element to the AT-AT.
