So I have looked, but there doesn't seem to be rules in any of the books about portable deflector shield generators (such as the ones used by the Gungans) or ground based shields in general (such as on the one at Echo Base). Has anyone written stats for these, or home rules as to how they work?
(I know a lot of the effects of such shields can be used as story elements controlled by the GM, but I'm sure these could be used during mass combat in interesting ways)
