1) If you'd like that listed, it'd be the unapproved material, A'unavaris'rhi. (Or however I spelt it)
2) Rechargable Battery/Charge packs thingy-ma-jigs. I figured it wasn't safe to put a fusion core in it.
3) Because it isn't obvious. The government already had a surveillance network prior to the RACTAG. They know it sends some information to the government, like vitals and stuff. They don't know it tracks where they are exactly, 24/7. That's when it was made.
Now, they've figured it out and Vero Emkal has disabled the tracking stuff. Normal Raiken citizens don't really care at this point. It keeps crime down, way down. Also, the Alliance wouldn't really tolerate anyone speaking out at this point, not with Vero Emkal lurking.
