ABRAMS TANK 1

First version, the treads were not made as movable.  Just the wheels can move.

I believe I have this configured properly.
All pivots set to proper rotation centers.
Here is the heirarchy:

Main Body

              Turret
                        Gun
                        Canon
                        The "domes" (1 piece)

              36 Wheels (9 pairs rt and left)
                               (middles are solid with
                                 track and do not rotate)

Please check this.  I believe I may have to redo the canon,  There should be 4 black spots on the barrel.  Maybe I can just import  a canon, fit, parent and re-export.
