Cobb

Cobb was a soldier of a Red Team squadron. He, along with 6 other soldiers, was locked in a room with the doors only opening if the seven troopers in the room could reach an agreement. After a murder-mystery surrounding the mysterious death of Hutch is solved (every single person in the room shot him for different reasons, Cobb's reason being because he wanted to be the Red Team leader), the Reds and Blues slaughter each other.

He, like Sarge and the group of Simulation Troopers seen in Fifty Shades of Red, has a thick Southern accent and is extremely zealous about warfare and his hatred for Blues.

Trivia

 * He has Achromatopsia (the utter inability to see color), coincidentally just like everyone else in the room.
