I tried a few more things and results are mostly positive.
Infantry can act as a cost modifier like the techoilderrick, however the modifier is triggered by an upgrade and can only be activated for one time no matter how many rangers (with the code pasted in its part) I built. That would mean we can still have something like an industrial plant but not something more complicated? Like a star port/ price fluctuation/ price increases as number of war factories incrase ... will all be impossible.
Units can also be an object prerequisite for another object. I made my ranger the prerequisite of burton and it worked out nicely. However when I tried to add Prerequisite
Object = AmericaInfantryRanger 5 (dreaming of making something available only when you have 5 rangers) Generals froze badly and I had to reboot my computer manually
Well thought I should post these .. and I will still update this thread
