Alliance are a serie of different mods. On the Star Wars GC, you can play the civil war Empire vs Rebel era + Black Sun and soon the Republic and CIS.
This is the monday new model, the Imperial TR-MB. It is unfinished, specially the texture but if you have some of imagination and you watched the film Universal Soldier, you will understand because they is a black line in the middle of the vehicle.;)

Yes, probably you are thinking it. I should have added it many time ago but Jedi_Consulor wanted it and other units from the old Force Commander game at his mod and I did not want copy his idea. Now it is not a problem, specially because I´m the owner from SOTE. This mobile base will be a great addition for the ground commanders.
Cool - is this for skirmish or GC?
Both. All the new units can be found at skirmiss and GC.
