His squad responded to Raptor's crash-landing and secured him in a nearby restaurant. When Ramirez's squad arrived at the crash site, he updated Sgt. Foley on the situation and helped repel the Russian troops long enough until a friendly convoy arrived to evacuate them. He can die at any point of the level after getting off the roof which is when he has said all of his lines. A character with the same name (But random appearance) can be seen in "Of Their Own Accord" and "Whiskey Hotel".
He can be seen in the first floor through a sniper scope of the Burger Town few seconds before the Russian Bombing: the bombs blown away the place where he was standing but strangely he's found alive with Foley and Morgan against a wall in the Burger Town while the bombing should have killed him.
Wells' appearance is randomly generated as well as the attachments on his SCAR-H.
