Makarov...

Price, Nikolai, Laswell, Soap, Gaz, and Ghost were in base going over Airport camera footage.

Laswell: “Security feed from the airport. Passenger had a boarding pass for Flight 761”

*Soap: “Fake passport...”

Gaz interrupted

Gaz: “Or inside job...”

Ghost: “Most Likey.”

Nikolai: “No one stopped him?”

Gaz: “Walk in the bloody park...”

Soap: “Wait...” *He takes a moment to look. He continues, with a heavy scottish accent, “That's Makarov. Sick bastard's topping American missiles with chemical weapons and killing his own people.”

Laswell: “That’s why I figured we could use extra help. Someone Price knows real well.”
