Still Battling on Rikkman Three

Well, I am still battling away on Rikkman Three. I realized it was unrealistic to think that the former Free Traders and other independent types that live on Rikkman Three, would not have set up some sort of defensive systems around their home. So I have been reworking the battle to put a little more "teeth" in the fight, from the viewport of the colonists, that is.
