What's the difference? I know Rare ones have one superior ground trait and Very Rare have 2 but I don't see a difference between the common (white) and uncommon ones (Green). Any info would be appreciated.
I found a Green BO that had the same skill as my White BO but at a lower level (actually it was higher level than normally available, something like Attack pattern III, which should be limited to II at the Cmdr slot.)
Other than that, not much I think. I also trained that skill to my white officer.
