Thanks you two. I redid it and have gotten it down to 900 polys. I'm thinking that I can reduce the number of subdivisions around the axis. First, it was 15, then I reduced it to 13. Anything lower will cause the normals on the face to align in such a way that the smoothness is reduced too much. The actual tread is exactly 100 faces, which is good I suppose. I think I'll model the rest of the tank and see how far I can get with 1000 polys. If I need more, I'll redeuce the subdivisions of the cylinders. Once again, thanks for your help.
