— In-game description
The Pursuit Helicopter and Response Helicopter are Scout Helicopters introduced in the Battlefield Hardline: Robbery expansion. Both vehicles share the same body type and only differ aesthetically, with the Pursuit Helicopter having a fenestron tail rotor while the Response Helicopter has an open rotor; gameplay-wise the helicopters function identically.
The Scout Helicopters function as a middle ground between the Transport Helicopters and Attack Helicopters, capable of holding multiple players like the transports but being small and maneuverable like the attack helicopters. Unique to the Scout Helis, however, is the fact they are unarmed; the only offensive capabilities they possess are passengers being able to shoot out of the helicopter and performing Roadkills. This regulates the choppers to a much more supportive role than the other helicopters, mostly being a dedicated transport to quickly ferry players around the map. They are uniquely able to equip the Mobile Resupply vehicle upgrade, allowing them to resupply teammates around the vehicle.
