Not sure what you mean by boundy box; well, I suppose you mean "bounding box", but still don't know if you're talking about the shield mesh or what.
In any case, a sub-unit is like a unit. Think of it as a ship that you attach to a base at multiple locations via units.csv, rather than in Blender.
If the subunit has a shield mesh, then each instance will have its own shield mesh.
-could we put a subunit on a subunit Y/N?
Yes;
ad infinitum.
-never multi uv map inside Or mirrored object mesh except if it's no emboss or black color? Y/N?
Not sure what you mean by "emboss".
If the diffuse AND specular colors of something are both black, then the thing doesn't interact with light in any way, so things like normalmap, AO and PRT's are irrelevant for it.
In a large station, you may have a lot of tiny details, like cables or thin pipes or frames or hex nuts, that if you try to unwrap them, even at a single texel width per face they would take a large chunk of your texture, so it's a good idea to make them pitch black. Then you can throw them all on a "black pile" in the UV map, and then shrink that whole pile to zero size, for good measure, and put it in a corner out of the way.
Also, when I have the UV layout done for a model, and afterwards I feel like the model needs more greebles or details, I just make the new details black so I don't have to reorganize the unwrap; and I just throw them into the black pile.
But there's another case of things that could be black in diffuse AND specular: Lights. Lights are black in diffuse and specular but have color in glow.
So, you can pile up all red lights in one spot, all green lights in another spot, all blue lights in another spot, and so on; AND you can also shrink each of those piles down to a single texel, so they take up the least room in the UV layout.
if you are more recommandations please write me.
(English correction: "write
to me" means send me a (hand-written) letter; you wanted to say "tell me" or "let me know".)
No further recommendations that I can think of, right now.
