The Unmanned Ground-Based Turret (UGT) is a mobile turret used by Stevonia. Before, when the UGT was still a prototype and top secret, Algernon was attacked by the Protom, and rUBY defended the planet with thousands of simulated UGTs. this was very odd, because it was unknown how rUBY found out about the top-secret project. rUBY later turned against Stevonia.
