Built under the supervision of Reth, it housed a large river of liquid Methane that ran into an artificial crater lake. Turbines used the river to generate energy for the compound, and giant reactors converted liquid methane into vapor around the crater, creating perfect conditions for the hundreds of thousands of Unggoy who inhabited the Redoubt.
During the Battle of Metisette, ODSTs and two Spartan-IIs from Gray Team landed in the Redoubt's central "Plaza" via SOEIV, not far from the river. They proceeded to neutralize Covenant anti-aircraft presence in the Plaza, then planted a Shiva-class nuclear missile in a sensor control building before being extracted by Pelican dropship to the UNSC Midsummer Night. The destruction of the sensor control structure blinded Covenant forces in the Redoubt, allowing it to be destroyed by several of the Rubble's asteroid habitats. Reth, the leader of the Kig-Yar forces, was killed by one of the asteroids when it collided with the ship he was attempting to escape in.
