Battle of Installation 03

The Battle of Installation 03 was a brief engagement on Forerunner Halo Installation 03 between the New Republic and the Covenant Remnant forces led by Supreme Warmaster Jul 'Mdamaee.
Several years after the Covenant's attack on Coruscant, Republic personnel on Anos Station detected a faint signal originating from the Khaphrae system, and a Republic Special Operations unit was sent to investigate, resulting in the discovery of Installation 03.
