EMS major emergency response vehicles (MERV) are modified school busses that are able to treat multiple casualties at the same time, with ALS and BLS functions. The unit seats 14 and has a stretcher, and is assigned to all major medical emergencies within its borough. There is one MERV assigned to Divisions 1, 2 and 5 each. Brooklyn no longer has a MERV, while Queens' MERV was lost to a vehicle fire.
