Not to much but this mod has the different units and clone cores

Basically, Republic at War is a Clone Wars mod that draws material from just about everything, whether Legends or Canon. It applies many new features, mostly small details, that were nonexistent in the base game, such as civilians without weapons. The Clone Wars Mod, however, takes most of it's content from what is officially canon, i.e. the Clone Wars TV Show and the movies, with only a little content from Legends, if any. It also greatly improves graphics and, one of my favorites for some reason, makes the Clone Platoons made up of individual soldiers. In other words, you can now send two or three individual clones to scout an area instead of having to use a whole squad. They are also made up of several types of troops, not just basic infantry. They are also trained in plattons, so don't worry about having to train one clone at a time, although snipers and clones with Z-6 Rotary Blaster Cannons are trained one by one. It also has many more heroes, and clone legions work differently. I hope that answeres your question!
