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.
Very useful these two pages from the comics, with them, I have added several new stuff to the mod and I am working at more new ground stuff which very probably I will release this year or in the begining from 2017.
Because there are other special AT-ST, I have made it as the scout walker from the Krayt Empire, of course the texture is from Nawrocki. There will be more units different between these factions, I will show you them the next days.
