KC4JGC,
The "metro tac" units are no longer called that, they have been absorbed by vice and narcotics. Channel G will be used by towing and recovery, animal control and the warrant office.
KQ4Z,
The "ocean" units are overlap units. Their unit numbers are like "242o", or "242ocean". But they are being done away with also after March 1st when the new 3rd precinct goes online.
As is stands now, the traffic units, which have been working on "H"-the detective channel, will be assigned to a precinct for the day and they will have to work on the appropriate precinct channel. They are not happy about that and I forsee that changing real soon. But thats how it stands now.
