LOL, if you look close enough, that's a T-34 tank hull on legs.
Looks more like an armored car, given the legs are mounted in what used to be wheel wells. The hull mounted MG and flat sloped glacius were common features on a lot of WW2 vehicles, as was the practice of strapping extra fuel to the side of the vehicle.
The Reseen version is a dramatic improvement IMO, and looks a bit less like a giraffe somebody tried to drive through a railway tunnel.
Yeah, the 2H and later models are drastic improvements over the 1H. It's a pity we don't actually have a model for the 6M there, it's easily the coolest looking quad mech in the setting (though only just, the Trebaruna comes close. It just barely loses out because it looks like it was stolen from Zoids for some reason).
