*stares blankly into space briefly* Cloaking? I know possible cloaking method, not the best, but still does a pretty decent job. [spoiler]Make it so their suits are totally electrical resistant, place a film of carbon on their suit. Run a high electrical current through the carbon, and this should give them very good cloaking [i]at night[/i]. Day time cloaking is much harder. This method only works for night or dark places[/spoiler]
