My first reaction was WOW!
My second reaction is....hhmmmm, how does it move?
I like the idea of walkers for WWW2, in general, and I understand the premise of "Weird" WW", but from a practical point of view, putting all that weight on 4 small points, would surely see it sink rapidly into the ground, and get stuck?
Particularly given its a russian model, with the infamous ground conditions of in Russia/Eastern Europe when the ground thaws, I would have thought some larger feet (to spread the weight) would have made sense.
Nitpicking, I know, but apart from that, looks great!
