Sgt. Derek "Frost" Westbrook
Manhattan, New York
The level begins with the player, Derek "Frost" Westbrook and Sandman climbing from the wreckage of an overturned Humvee in Manhattan. They emerge to find themselves and a friendly Stryker battalion under attack from Russian infantry and vehicles. The player fights his way up the street, past heavy resistance, and meets up with a convoy of Strykers at the corner of Exchange and Broadway.
Frost, Sandman, and the convoy are then ambushed by a Mi-24 at an enemy roadblock, forcing the team of Deltas to circumnavigate the road block and enter another building. After they clear the shop and alley, they meet with Grizzly and his team of Deltas, as they fight in front of the Stock Exchange.
As the team reaches the New York Stock Exchange, they fight their way through the trade floor and take a service ladder to the roof. Using thermite, Frost destroys the radio jammer on the roof, restoring radio communications to friendly forces. They then come under attack from enemy forces positioned on some nearby rooftops.
Frost uses guided missiles from a Predator Drone to neutralize the enemy troops on the roof, as well as an enemy gunship that arrives to provide support for the enemies. A Black Hawk then flies in to extract the team, but they are pursued by several Hinds through the Downtown Manhattan airspace. The player, manning a minigun, destroys several gunships. At a nearby construction site, as Frost destroys one of them, it hits the Delta team's Black Hawk as it crashes into the scaffolding. The impact causes the Black Hawk to spin out of control, having Frost nearly thrown out of the cabin. The pilot eventually regains control of the helicopter and the team is briefed while proceeding to their next mission in New York Harbor.
