Great model.  I am sure the ammo belts can be made in Bryce.  It would just take some extreme parenting/linking work.  If that one artist ,whose name escapes me, can make dragons and people from stacks of spheres I am sure this is possible. :)  Might have to try this.  Hmmm...

The top belt is the easiest.  2 MR'd groups, 1 straight, one curved on 1 axis.
Side belts.   1 or 2 MR'd groups with tweaking.  

Could use a posed smartpipe as a guide.
