Chips Dubbo

Background
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 (It is likely that it is, in fact, Dubbo.)

Chips Dubbo was a UNSC Marine stationed on the Pillar of Autumn. He escaped the destruction of the Pillar of Autumn along with most of the other Marines using escape pods. Dubbo met the Master Chief on Halo. He later on went with Keyes, who took two fire teams (Dubbo included), 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 Second Squad, escaped the facility and then met up with the Master Chief again. Chips and the few survivors of his team were picked up by Echo 419. Oddly enough, he also participates in the Silent Cartographer and Control Room missions, even though this conflicts with his being with Keyes.

Mysteriously, he made it out alive along with Gunnery Sergeant Pete Stacker, as well as Sergeant Major Avery J. Johnson. After the events on Installation 04 and Cairo Station, he was deployed into Old Mombasa at Hotel Zanzibar. Here, he encountered John-117 again. Later he managed to board In Amber Clad to survive the city's destruction. Afterwords he assisted John-117 in killing the Prophet of Regret. After surviving The Second Battle Of Earth, he went through the portal to The Ark and took part in the Battle of Installation 00. He then escaped the Ark with the rest of the surviving Marines and Covenant Separatists, and became one of the survivors of the Human-Covenant war.
