Lieutenant Simon "Ghost" Riley is a British special forces operator, and a prominent member of Task Force 141, known for his iconic skull-patterned balaclava, headset, and dark red sunglasses. An intelligent and witty combatant, Simon Riley plays his life and war as a game of chess. Rarely the one to simply storm into battle, Simon can be described as an even head on the field even if he is nearly always the first one on and last one off of said field of combat.
