I was interested in rigging a tank so I found this Pz.Kpfw VI Ausf.H Tiger model on ArtStation. The model is by John Olofinskiy.

This rig has a high poly and low poly proxy layers to adjust for animation work and rendering. The wheels have an offset group which can be constrained to the ground plane for added suspension. The fire and recoil attributes can be easily adjusted to affect the body roll when firing the main turret.
