Scientist, creator of the Super tank
He wished to defect to the Allies and bring the Super Tank designs to their cause, so thus he reprogrammed the tanks to fight for the Allies. But due to a mishap, they began destroying everything they perceived as a threat until they were successfully reprogrammed for Allied use. He meanwhile had taken refuge in a nearby civilian town to await any form of evacuation.
Demitri is escorted out of village under the cover of the Super Tanks rampaging inside the Soviet base, and evacuated by a Chinook, under the player's supervision.
Demitri appears in the Aftermath expansion pack.
