Still working on this, as am also doing some re-jigging of the files at the same time. Asterians pretty much done, was working on Enforcers over the weekend. Not all files will get the re-jig at this point (in the interests of getting a new release out more promptly), but those with new units will.

VeerMyn, Plague, and Marauders done in other pushes.
