Fighting alongside the full squad for the first few minutes of the mission, he is then assigned by Captain Price to guard the rear of the unit with Wallcroft while the rest of the unit breaches the cargo hold. He and Wallcroft board the helicopter, before they spot some incoming MiGs which subsequently open fire on the ship. He survives the events of Crew Expendable.

During the chase the train over turns and their vehicle collides. Although Burns and Wallcroft survive the impact Griffen is killed along with the rest of the SAS team.
