Alpha Three is a 1999 Ford Explorer, with modifications done to allow it to work in a first response role. It has a strobe lightbar package, wig-wag headlights and strobes. It carries the same walk-in equipment that the ambulances carry, and some additional immobilization gear. These units stock some bulk amounts of drugs and supplies so they can stay out and work consecutive calls if necessary.

Presently this unit has been removed from service. Its service area is now handled by Medic Six.

Quick Response Vehicle (QRV) -- An emergency response medical unit that is equivalent to a standard EMS response unit with only two differences: one paramedic staffs the vehicle, not two; and the QRV has no patient transport capability. This unit is dispatched to scenes where no transport is expected, or to assist a responding ambulance.
