The scene switches briefly to a number of Single Occupant Exoatmospheric Insertion Vehicles falling through the atmosphere.
- Colonel Mehaffey: "Drop behind enemy lines... attack from the rear.. and neutralize."
Between Mehaffey's lines, the scene switches back and forth to the cadets advancing through gunfire in a forest on an exercise. They take cover.

- Thomas Lasky (exhausted): "You're gonna get us all killed."
- Walter Vickers: "They're my orders."

Cut to General Black then to Lasky is seen marching past a Warthog, saluting. Scene changes back to Lasky and Silva, who begin to kiss. Their kiss is interrupted by the alarms suddenly going off and the academy's personnel rushing up the stairs.
- Marine: "This is not a drill! Move! Move!"
Lasky and Silva run up to the rest. Several cadets and Marines are seen running down a hallway.
- Thomas Lasky: We're under attack.
Everyone looks up, seemingly into the sky as lightning strikes.
- Thomas Lasky: "What the hell are those things?"
Explosions pepper the cadets as they run for cover.
- Thomas Lasky: "Go!"
Cadets scramble and fall down as explosions continue to pepper. Michael Sullivan speaks into a wall-mounted intercom unit.
- Michael Sullivan: "Mayday!"
The camera cuts around the room frantically. A door is burst from its hinges. A Stealth Sangheili approaches the cadets, creating a ripple in a pool of water. As the cadets cower, an MA5 is heard discharging outside the room and the Sangheili lets out a quick scream. As the cadets cower, John-117 steps through the doorway.
- John-117: "Stay close to me. I'm your best chance for survival."
Several cadets are seen running around outside. The shot then changes to Orbital Drop Shock Troopers firing at Covenant forces off screen.
- Vickers: "It's a whole new war."
The camera briefly cuts Orenski then to what appears to be Insurrectionist graffiti on a wall. It shows an upward-held fist and the phrase "EX-TERRA". Scenes of combat continue to be shown. Lasky is seen taking cover next to Silva.
- Thomas Lasky: "You okay?"
- Chyler Silva: "Go!"
The combat continues. Two cadets in battle dress are seen locking hands. Silva, tired, closes her eyes in despair.
- Lasky: "Chief!"
- John-117: "Drive!"
The Warthog speeds ahead. More shots of combat are shown.
John and several cadets are seen running as explosions go off around them.
There is a closeup shot of John as he slowly turns his head to face the camera.
