Riley joined the US Army in 2009, and joined Will's platoon, as one of the greatest Machine Gunners of all time. He was the "paperwork boy" on Pratt-Whitney AFO, and quite honestly hated his job. He is good friends with Cpl. Lucas, and cares for him deeply.


Riley stood by Harris's side and held HQ from a large group of zombies in the begenning. The undead didn't get in, but Riley was nearly bitten, and scratched all down his leg.
