He is seen at the end of the helicopter supervising the Marines out of it and covering them with an M9. Due to the last minute rescue of a Cobrapilot, he is killed when the nuclear bomb explodes. The bomb's shock wave causes the helicopter to spin uncontrollably and he is hurled out of the helicopter from the force. He is one of the 30,000 who died in the events of "Shock and Awe".
In Modern Warfare: Remastered, when the nuclear shockwave impacts the helicopter, the player's character, Jackson, attempts to save Volker by reaching out his arm, but the G-forces still cause him to get thrown out of the helicopter.
