Krupin is an engineer that went missing. Pvt. Doherty, a medic, is seen fixing him up after the player, Dixon, and Guzzo split from Huxley. Before splitting with Huxley, Krupin provided details of what happened before regrouping with the squad.
He and his squad found a squad of Germans up ahead in an enemy storage depot and his entire squad was killed while he was wounded. The squad then advances towards the storage depot. They regroup once they clear the storage depot and the barricade about a couple of kilometers away.
