I've been stalking this for a while and decided to start up my own submission.
Currently working in Onshape so everyone can go in and poke around the assembly if they want.
I still got a long way to go but it's a start.
Next up is finishing the powerpack, inserting the turret blockout, designing the autoloader, modeling the sponsons, skirt armor, suspension.
I'll Probably be done with most of that by Monday.
As a side note a lot of the parts in the assembly don't have the correct mass as of yet...
