Which Neutral Powers would have the economic equivalent of a “Minor Industrial Complex”?
I think Spain, Turkey and Sweden are the obvious neutral powers that have a large enough industrial base to build their own tanks, planes and ships. Depending on how the sculpts are going to look, I think the Italian burnt orange will fit Spain, and maybe the french dark blue will fit Sweden. Turkey already got their units.
Maybe use the medium green for Brazil, and lime green to supply China.
Maybe even Canada can have own nation specific units ?
The Russian maroon will fit Mongolia I guess
