The Toughest Bases and Stations

[Raziel]

I'm slowly cobbling together a guide/faq of tips/tricks to assaulting ground bases and starstations. However I want to make sure, the various nifty things I have found are not just due to weak targets.

So I am looking to you all, to find out what people consider the toughest, most impenatrable areas and let me crack'em wide open....hopefully.
