Well, yes I do actually work in research, and there is a protocol associated with everything you do
Its very different between universities, where profs sometimes do keep it all to themselves, and opposite, when you work for a corporation, where your work is their money, and, oh, they don't want to loose any of that.
To be quite frank, I do not see how would civilians be helpful in base defence mission. Or well, I do see how they can be, but I do not see great benefits of it, versus the drawbacks of having more units to mange or account for, risking loosing your untrained 60k investment, and general lack of plausibility.
If we were to continue the line of thought of similar events during the game, what I would be thrilled to see are various factions that are with/against XCOM on the missions. Why terror missions never have LAPD/etc officers that are armed? Why facilities that you go to defend never have their own security staff or a guard at least? Why not have military be present alongside in some of the missions, where they are progressing in organised manner, as your XCOM soldiers, but just with earth equipment?
Of course all of these would be AI controlled.
