I just wanted to say this:
If you are adding the units to DAC, then you have to use the battle_models.modeldb-file found in the dwarven download, as that one has both the dwarven and the elven units incorporated in it.
The one in the elven download only has the elves.
And i think you need to add both mods, but i am not sure- as the modeldb-file have all the text added for both the elves and the dwarves when adding the dwarves.
