Red and Blue Civil War

The Red and Blue Civil War (also known as the Simulation Wars or simply the war), was fake proxy/civil armed conflict during the waning years of the Great War. The war was fought mainly between the Red and Blue Armies, with Freelancer agent support. However, the conflict was actually a ruse to have both armies be used as human guinea pigs by Project Freelancer to test their soldier in "realistic" battle scenarios.

By 2553, the war was put to an end when the crimes Project Freelancer committed were exposed to the public. All remaining simulation outposts and soldier who wished to continue the fight were then put under the jurisdiction of the UNSC.
