While the TCUs are no longer used, the concept lives on within EMS operations. There are two station/battalion level commands (the Bronx Tactical Response Group and and the Queens Tactical Response Group) which exclusively operate tactical or ‘enhancement’ units.
These stations do not run overnight units; all units are Tour 2 only. Instead of being designated by the battalion in which they are located, the call signs for these ambulances are designated with a number 8, followed by the number of the EMS Division in which they are located. Like other units, the call sign is completed with a letter. For example, 84B would be a QTRG BLS unit and 82F would be a BxTRG BLS unit. (Note: the TRGs do not run ALS units.)
The Bronx TRG is located at EMS Station 18, next door to the quarters of Rescue Co. 3. The Queens TRG is located on the grounds of Queens General Hospital, around the corner from the new EMS Station 50. The units log on at their respective stations and are deployed throughout the city as needed. These units are sent to areas of high call volume or to backfill units that are OOS during peak hours (tour 2).
