A soldier in a gas mask uses a tool to cut through a metal prison door, sparks flying, as another soldier stands nearby in a dimly lit, industrial corridor. The scene shifts to a soldier in tactical gear moving through a war-torn urban environment with burning buildings and debris, then to a soldier in a dark, industrial setting with a life preserver on the wall, followed by a soldier in a helmet and gear observing a damaged helicopter amidst rubble and smoke.
