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.
I have added more ground units to the Hapans. Here you can see two more, the AT-APT and the APC. At my site you can see other two walkers, one special heavy AT-ST similar to this Images.wikia.com , a AT-RT piloted by a Hapan soldier and a special HAV Juggernaut.
