Cole Anderson (known as Cole-G004 before the post-war) served as a Spartan-III in Gamma Company before becoming a Spartan-IV. He is best known for his skill with explosives and hazardous materials that could be deemed dangerous to the normal UNSC demolition soldier. He served alongside Mark Sullivan and the two became friends ever since the Human-Covenant War. While he is not with his team, Fireteam Wolf, he participates in side ops with other Spartan fireteams and often helps the UEG Police Departments bomb squad.
