The Juggernaughts, as near as I can tell, aren't different
from the conceptual drawings of old... I'm digging not only
that Lucas saw fit to use an old design which had already
been incorporated into EU, but also that there's a seemingly
HUGE variety of vehicles being used in the war. A technological
arms race not unlike what we see on Earth in times of great
The AT-RT, the Juggernaught (screw "Turbo Tank"), the 4-legged walker
there on Kashyyyk with the Juggernaughts (A seemingly heavy fire support
walker of sorts... Similar body to the AT-TE so it could be a variant of the TE
actually... Not uncommon for Earth military vehicles to see just simple
modifications), the BARC speeders, etc... Plus Lucas's adoption of the ARC
trooper armor. Great stuff.
Much more involved creatively than AOTC and
TPM were it seems. A bit more of his "military"
thoughts that were in the Classic trilogy seem
to be in this last prequal film.
