When the truck was rehabbed/repainted they went with the designation Tactical, instead of Tactical Support Unit. This was the original TSU 1, which was just replaced with a 2009 E\-One Cyclone II Heavy Rescue. The only one of its type. There are 3 Tactical Suppor Units within Halifax's "core" section.
TAC 1 - fully staffed crew of 4 out of #12 Station
TAC 2 - crew of 2 out of #8 station
TAC 3 - staffed as needed, collapse, high angle rescue out of #3 station
TAC 4 - reserve TAC unit, also was supposed to run as department Decon unit out of #5 station
