The space part was fairly easy, I built max space units, and a couple of troopers.
Went into the astroidfield with 4 x-wing flights, 3-Y-wing flights, 2 CR90 Corvettes, 2 Nebulon-B Frigates and the Millenium Falcon.
Once I was spotted my tactic kinda went all to hell and I ended up charging in everything I had.
Anyway, lost a frigate, all y-wings, 2 complete x-wing flights, and almost all fighters in the other 2 flights.
Started to produce ships and ground troops, and went to Tatooine, only to realize, there are no enemy space units above Tattoine.
Oh well, so I landed my troops, and started to look around. But before I knew it I was under attack and lost almost all my troops that I had initially landed.
Took about 10 minutes before I had the upperhand, found the artillery excellent against pretty much everything, when I was able to protect them well enough that is.
Captured the left Control Point first, landed some more troops and tanks to secure it, then went for the right one. Once I had that one, I positioned my remaining artillery behind the power generator. Had 1 group left of 3 or 4 that I brought with me. I lost those in the initial battle before and during the time I fought and captured the AT-AT. Once the power was out and shields was down, I sent my bombers to take out the light vehicle factory.
After that it was just a matter of mopping up the remaining resistance.
