Another maybe harder unit animations question...

I have a model from WoW that has a sneak animation as well as the standard walk or run animations.

Is there a way to toggle which animation the unit is going to be using? Do I need to create an ability similar to defend for footmans?

Do you mean through triggers? You could just count which animation # is and play it through animation index.

Name it something like "Walk Alternate" or "Walk Swim" and just use triggers to give him the Alternate or Swim animation tag. Alternately, use an ability which does the same thing.

Well... you can go to the unit editor, and add to the "Art - Required Animation Names" category the text Alternate. That would make him walk the alternate way, I think. (I heard a tutorial on it somewhere).

The animation tag can be used to change the constant animation of a unit in game (like making a Blademaster look permanently bladestorming). You can also remove it later when you want it to stop.

Actually will that make him keep playing the sneak animation even though he's standing still (assuming no trigger interaction) or or could I replace his walk animation with his sneak and vice versa on the fly?
