Maya Rigging Tutorials for Video Games?

NURBS

Hello there. I'm trying to learn some rigging so I can make a playable tank I'm making for use inside Unreal, but I can't find any tutorials that help me. Nearly all the tutorials I come across are either for rigging characters or are for rigging stuff to be used in movies and TV, not games. Does anyone know of any tutorials out there that are for rigging a vehicle in May for use in game engines? Or am I approaching this the wrong way and should just watch tutorials until I learn stuff?
