Couple of suggestions
What about AWACS (radar VTOLs) would be really helpful, I can think of a few tactical uses for that.
Would also be nice to get the Wide Spectrum scanner into the campaign mode maybe around beta 8 as there are 4 artefacts but only 3 of them give you something to research so maybe make the 4th the wide spectrum scanner
I'd also move the Pepperpot Tech to the end of Alpha Campaign because by the time you get it its already obsolete as you already have ripple rockets, if you move I to the end of the Alpha campaign atleast you would get some use out of it before you upgrade to ripple rockets
