Ok, it's working OK now, but I think the air forces are 10x Hoi2 level overpowered, or at least in the Iran Iraq war scenario I played were.
I think you could make air power more doctrine/terrain dependent: in the Kosovo war NATO air forces did little to no damage, but in the Gulf War they were devastating, so idk if you can edit terrain to modify air attack but that's be good. You should need good terrain + modern doctrines to do as much damage as you can do now in the scenario I played I think.
Also, I can't seem to declare war. Understandable to stop AI attacking each other, but since this doesn't happen really anyway I think it'd be more fun if you could.
