Not in my experience. Of course, I don't exactly have a Confederation security clearance. [Who knows, maybe it's standard procedure around here. But to him, it seems an awfully big power drain for a small outpost like this.]

The technology's been refined over the years, but I've only ever seen it used to cloak ships. There are holograms that could be used to disguise things, but I haven't seen any sign of a holodeck since I got here, and a holodeck doesn't emit tachyons, either.

We've got a real mystery on our hands here.
