The way I see it the Empire is what Oz was on its way to to coming. This battle will be conduct in a similar way as the Dominion vs. the Empire battle.
The two armies will battle in our solar system and any land battles will be fought in the Arizona desert, or any flat generic land.
The mobile dolls work in both environments. Oz also has the Libra space station that they almost blow up the Earth with.
The land battle would be won by Oz since the mobile dolls are more powerful and agile than AT-ATs and AT-STs. Stormtroopers
are like ants to these things. But this battle doesn't take place unless the troops can land on earth. Now here is where the battle is exciting
The mobile dolls are just as agile in flight as a TIE and just as fast. The Death Star is the one thing that the Empire has
that I find trouble defeating in every universe or group battle. In this battle it is a major player. I think that Oz could use Libra station against it.
I am assuming that each station takes the same amount of time to power up. The Death Star is too slow, however, to hit the mobile dolls. Once they are all
deployed, it won't be able to stop them all. The average mobile doll is more powerful than the average tie fighter. The mobile dolls can infiltrate the star
destroyers and cause damage. Its like ants attacking a bird, the are all over, biting. Eventually they would destroy everything but the
Death Star, but it is only a matter of time until it has to open its ports to bring in damaged ships for repair or to release new ships for battle. When this happens,
the mobile dolls will infiltrate the Death Star.
