Light, Medium, and Heavy tanks are all done with, so let’s move on to the rest of the tech tree. I will be combining the two branches into one article, since the potential for extra hulls is a bit lacking on the SPG side.
Tier 2 does not give us very much. The AT-1 was released in a very limited production run (10 units), and it is unclear how far the SU-18 made it off paper. The tier 3 SPG SU-26 also does not have much in the way of alternate hulls. Since these vehicles were improvised in Leningrad during the blockade, the hulls are likely to vary visually, but nothing that would have any effect on the gameplay.
The SU-76 on the other hand is where we hit the jackpot. Aside from the experimental SU-16 (one drive wheel shorter), there was a variant of the SU-12 (SU-76′s initial index) with a 6 mm roof. My personal favourite would be this variant of the SU-76M, with a fully enclosed crew compartment.
