Tank (treads) code??

Can I create a “tracked/tank” vehicle code in Unity3D? is there already some code available? My engineer is having a horrifying time trying to do this in TGEA.

Sure. Does it have to be physically correct? Because that would be harder, but I think most games just animate the tank tread texture, which is simple. If I had to make a “real” tread, I’d probably make a skinned mesh with a bunch of bones, and animate the bones in Unity.
