As requested I have uploaded the model. 2 archives, one with both model and textures and one with just the model. Turrets are not included.
The model files include 4 groups,
1. 1/2 untriangulated models with symmetry objects
2. 1/2 triangulated models with symmetry objects
3. full untriangulated models
4. full triangulated models
I exported the file to several different formats because most here do not use Cinema4d and I do not know how the export to each format affects the symmetry objects or even the UVs.
