Sergeant Pierre was on the original SECFOR mission that gave rise to the OIL in 2006. He's since deployed with the 158 again and is still in the military. He's originally from Panama but has called Lawton home for many years. He lives there with his wife, and is still in the Oklahoma Army National Guard. 2015 was his first season in the OIL.
His team is named after his MOS. Pierre and the rest of the 158 mechanics kept the humvees rolling through 110+ degree heat, IEDs, small arms fire, and the most aggressive driving possible.
