Firefly is the callsign for a Stryker ICV featured in Call of Duty: Modern Warfare 3. It is seen in the mission, "Black Tuesday", providing support for American soldiers fighting during the Battle of New York. It is equipped with the M2 Browning machine gun. In contrast to its ally, Frolic, Firefly is destroyed in battle, being hit with rockets from a Russian helicopter. It is however possible for Firefly to survive, the only way being to run into the building that Sandman orders the team to go into before the helicopter appears. Firefly will be intact and fighting when the player goes upstairs, but this will have no effect on the mission.
