This is the M1A2 SEP Abrams tank.
This is by far, the most detailed Abrams tank ever built, and also the most accurate.
This is actually a portfolio project, it was not meant to be sold. The level of detail is insanely high because it is meant to be a showcase model.
This project took 9 months to be completed, gathering more than a 1700 photos, including books, documentary and videos.
It was built entirely by subdvision modelling, which means you can apply meshsmmoth or turbosmooth, on any piece of the tank.
IMPORTANT: Theres no meshsmooth or turbosmooth applied to it.
With meshsmooth lvl 3 applied, it has over 376 million polygons.
Because of the large size of the files, i've split it into 4 parts, so you must unpack first, inside there's a readme.txt that will guide you.
There's an extra pack which contains the tank in .obj format, in order to get all the zbrush pieces, you must download the pack that was split into 4 parts, and then, unpack, you'll see a folder with all the pieces made using zbrush.
The original file is 3DS Max 2009
Four renderings in high resolution are available for download.
Three viewport wireframe screenshots in high resolution also available for download.
