I think my very first post here was about removing the "Come on!" scene or adding troops jumping out of the AT-AT. As it stands in the film, it seems like one guy on a suicide mission. Especially since the speeders double back and destroy the AT-AT... even though the armor is "too strong for blasters"...

Ady's fixed the destruction so that the speeders seem to blast a damaged spot on the neck, which is a neat fix, but seeing troops repel out of the AT-AT and engage the rebel troops on the ground will always be a dream of mine. I can hardly even imagine how it could be done though... seems like it would be expensive too.
