So who's up on the "math" of Civ6 to say what could stop a GDR? Like say I attack a GDR with a mechanized infantry army or a modern armour army, how much damage would I be able to inflict? For the purposes of the discussion, let's just say the initial version GDR without upgrades. They hinted it would be more vulnerable to aircraft. A jet bomber has bombard strength of 100, less than a mech infantry army or modern armour army melee strength, but fairly easy to have 4 or 5 of them strike a GDR. I would definitely aim for the promotion against ground units. Because honestly I don't really want to build one, but I do want to be able to defend against an AI built one. And I do hope they build them. I really only see myself building one for the novelty of it (and most likely there will be an achievement for it).
