Well, I had trouble naming this one, so my daughter suggested RPM attack. 'What does RPM stand for?' you would ask... And no - it's not rotations per minute Has anyone played Starcraft II? My daughter absolutely loves Protoss and their technologies. So, in her opinion, RPM is a Rogue Protoss Mothership. The Rogue Protoss were silver-and-green, while the good ones (well, at least when playing Protoss levels) were gold-and-blue. I would say it's a mixture of both, a new breed Anyway, thanks to my little angel for the suggestion. Although they don't look anything like Protoss motherships, but... So be it...
