GW

While temporarily crashed by Emma's worm cluster, it was recovered and repaired by Liquid Ocelot. GW is one of four optical neuro-AIs that comprise the Patriots' AI system, a fact that he exploits to gain access to their system. After Arsenal Gear crashed into Manhattan, it was transferred to Outer Haven, with GW's server housed deep within its bowels.
