They're often static, meaning they can't pass through other objects. The model is skinned, which is the individual textures that Blizzard is using for different characters. Inside of the model is the skeleton, which is made up of bones. Each bone is attached to a pivot, which you can use to adjust the model's arm(or any other attachment) to what you want. Animations are recorded by taking "screen shots" of the model while adjusting the skeleton. The more screen shots you take, the longer the animation takes to complete. So in theory, all Blizzard needs to do is take their saved states of the orcs, add more bones to the skeleton, and take more screen shots to make the final animation smoother. The skin is a completely different story, as skins are normally applied as completely flat imagines which "wrap around" the model. I hope this clears some things up
