Here is my six-wheeled amphibious tank-design with some improvements for the rig.

I tried to create a simple rig animation control with ground detection for the wheels and the suspension.
Also I added some animation-constraints for the steering wheels in the front and the rear, the guns and the outboards.
The animation happens on bone-layer 1.
Just for fun I created a driving through a wall physics animation
by using cell fracture.

Feel free to use it for non-commercial projects.
Modeled and textured in [3D-Coat](http://3dcoat.com/de/home/) for rigging and animating I used [Blender](https://www.blender.org/download/).
