Very interesting concept, never heard of it! I love the gas masks and this iteration of Paznerfaust!

With some modification an enterprising modeler could make these figures East German. That panzerfaust is very similar to the first RPGs.

With a bunch of the crabmines, you could make a depressing little post-apocalypse diorama with something like a cutaway into a bunker, a desiccated corpse in a corner, with racks of crabmines on the walls, a few of them waking up to climb down and exit through a narrow slot to a beaten-up countryside (à la WWI no-man's land) with another corpse face-down in a crater outside. No one winning but the machines.

As if reality isn't weird enough...
