Chips Dubbo

Private First Class Chips Dubbo (voiced by Andrew McKaige) is an Australian Marine in Halo: Combat Evolved. His distinctive dialect, unmistakable smart remarks and laid-back attitude make him instantly recognizable. A similar Marine, voiced by the same actor, is present in Halo 2 and Halo 3. Chips Dubbo is a UNSC Marine and ODST stationed on the Pillar of Autumn. He escaped the destruction of the Pillar of Autumn and met the Master Chief on Halo and later on he went with Keyes, took two fire teams and went to find the "weapons cache" that 'Qualomee had told them about. The cache later turns out to be the Flood containment facility and he and his team, along with the remains of Lovik's team, managed to escape the room and then met up with the Master Chief again. Chips and the survivors of his team were picked up by Echo 419.

After that, it seems that perhaps Dubbo was extracted from Installation 04 before it was destroyed and that he soon aided the Chief in his battle on Delta Halo.
