Static parts of an Animation in Unity

I'm fairly new to Unity, and wanted to make a simple 3D game. I've got a turret model I designed in Blender, and can import it into the game no problem. However, the turret has two different parts: the turret head and the base. I want the base to remain stationary but the head free to rotate, being controlled by a script. Is there any way I can do this without separating the model into 2 parts?

 

Well turns out I answered my own question, and just wasted an entire day. Unity automatically deconstructs objects based on groups, so no need for separation.
