Chief is a member of the black ops A.R.G.U.S. field regiment, the Oddfellows. He formerly served with the Shadow Wolves, a unit of Native American trackers operating in the U.S. Immigration and Customs Enforcement who track smugglers through a 76-mile stretch of the Tohono O'odham Nation territory that runs along the U.S./Mexican border in Arizona.
His experience in the field enabled him to assist refugees and illegal immigrants, a deed that landed him in trouble with federal authorities. As recompense, he joined A.R.G.U.S. as a means to commute his sentence, and offers the team his skills in manufacturing explosives. He's also an amateur jewelry designer.
