Dummy Faction

These robots were originally designed as test subjects for weapons, vehicle safety measures, and other lethal experiments, but an AI controller became sentient and broke off from it's manufacturers, starting a new line of robots and weapons to defend itself.

TL;DR: A rogue AI broke off from a crash test dummy production facility and made weapons, craft, and robots using parts from said production facility.
