But fighting itself isn't simply about individual weapon system capabilities, but how they work together. Armored divisions only had a handful of battalions of actual tanks at most, the far greater proportion was infantry, artillery, anti-tank artillery, signals, recon and logistics elements, etc. Once this is all put together, on the whole, the capabilities of similar division types was largely similar. Not that I don't agree that technology wasn't important, but it was only one of a trinity of things that made the capabilities of any fighting unit what it was, and the least important at that. IMHO I'd rank the three like this: tactical doctrine, then divisional organization and only then the actual technology used. All three should be present in the tech tree, for instance, and should depend on each other so that you can't really ignore one to rush on the other two or anything, but doctrine would have the largest single set of effects, then organizational, and only then technology.
