You know that stereotypical giant wall of TVs view of camera security? It's basically that, only through a camera, so it gives you a good (if chaotic and occasionally desynched) view of the internal cameras over on the front and outside of the building. You can roll to get a better view of that combat team. For the drone, as long as you sustain it, the drone acts as if you left, despite the mark.<br/><br/>So if you erase the mark and then drop the veil, no need to hide again. It won't do anything if you show up with the mark, it's just a little liability because the owner could (theoretically) get your location from it.
