Well, I guess what got me thinking about it was the NAS-81, which is oddly similar to a reasearch drug called NAS-181(I work in the pharmaceutical biz...). Strangely too, this drug is being used in studies to treat depression, and RFS sure did look depressed sitting there in his monster encrusted hut.
I'll have to go with the previous post on "Robotic Fighting Servant" for RFS-81. It's too obvious to not be it. Once again, yes, think military.
NAS...?
