How do I use the troll beserker model for a unit?

[Mullit]

The problem is that the headhunter and the beserker are the same model in the object editor and I want to use the beserker one for one unit and the headhuinter one for another unit.

thanks in advance

you have to put in "alternate" in one field value of the unit
I just cant remember which one...
I think its Required field animation??

For Troll Berserkers, it's actually needed several times:
Art - required animation names
Art - required attachment link names
Art - required bone names

All to be set to "alternate".

And, actually, it would have been enough to have a look at a Berserker...
