Police

Police are units of civilian law enforcements. They can be a friendly or hostile faction, based on the mission.

Zakhaev Airport Security
The first police faction to appear in the Call of Duty series. They were the first responders to the attack on Zakhaev Airport. They desperately tried to stop the mass murder, but were quickly gunned down. Failing in putting a stop to the massacre, they called in the FSB.

FSB
Called in to stop Makarov's terrorist unit. This attempt failed, despite them being well armed.

Virginia PD
While not seen directly, their wrecked police cars littered the streets. It is possible that they fought back against the Russians.

Havana Police Department

US Military Police
They escort Alex Mason, Jason Hudson, Robert McNamara, and a Unknown General to the Pentagon for Mason's meeting with John F. Kennedy. They are also zombies in the map Five.
