This one I did as a nod to my Russian readers (one of whom does the interpretation of the Russian language in my comic), who have pretty well dismissed the concept of gigantic robotic tanks. Don't get me wrong, they all have been perfectly willing to accept the idea of a giant tank as a main character, they just scoff a little at the idea of it, on principle.
So I came at the Russians' military robots from a different angle. Where the West, in my story, have been building big and impressive machines like superheavy tanks, the Russians have opted for smaller, more numerous, and more maneuverable robots, like this one, which is basically a heavy infantry combatant. I really liked the design of this one, though it could use some tweaking. But, hell, it's just a concept. And a big robotic walker like this is just a fun sci-fi idea.
The project number, by the way, I got from the clock: it was 7:45 PM when I started the sketch.
