Red Zone

The red zone is the name given to an area in and around an unnamed town in Afghanistan in Call of Duty: Modern Warfare 2.

In-game
The red zone is only seen in the mission Team Player. PFC Joseph Allen, Sergeant Foley, Corporal Dunn and other Rangers battle to gain control of the town and drive out the OpFor forces stationed there. Intense urban fighting at close quarters takes place, but the Rangers finally manage to successfully gain a foothold in the town.

The red zone is not seen anywhere else in the campaign.
