- Tyson Rios - Tyson Rios originally worked as a mercenary for the private military contractor SSC (Security and Strategy Corporation) with his long-time partner Elliot Salem. They later left SSC to form their own private military firm called T.W.O (Tactical Worldwide Operations). Rios' life of combat eventually came to a tragic end from a car explosion, leading to a badly injured left leg and the presumed death of Salem. Unable to continue to work in the field; Rios commands T.W.O operatives as an executive.
- Elliot Salem - Elliot Salem, together with his long-time partner Tyson Rios, originally worked as mercenaries for the private military contractor SSC (Security and Strategy Corporation) and later founded T.W.O. (Tactical Worldwide Operations). His actions appear by choices in Arrmy of Two: The 40th Day; the ending is chosen from Jonah and is canon for Arrmy of Two: The Devil's Cartel. Salem went insane after a seemingly fatal incident caused his partner and two other T.W.O. operatives, Alpha and Bravo, to abandon him to save hostage Fiona. This caused him to become a villain alongside his boss Bautista in The Devil's Cartel.
- Alpha - One of the two playable characters in Arrmy of Two: The Devil's Cartel . His name is not revealed so that the player may "project themselves into the character a bit more". Alpha is considered the de facto leader of the pair since he is often the one who comes up with the ideas and battle plans. He also keeps his hot-headed partner Bravo in check during tough situations and does his best to steer him in the right direction in order to complete the mission.
- Bravo - The other playable character in Arrmy of Two: The Devil's Cartel. His name is not revealed so that the player may "project themselves into the character a bit more". While Alpha is focused, calm and collected in battle, Bravo is the complete opposite: he's gung-ho, tough as nails and always ready for a fight. Besides that, he is mostly a funny, wise-guy comedian who loves to cracks jokes and make fun (especially of Alpha).
