Careful here - what was the NIFC system as we knew it for a long time in the fire comms world (national interagency FIRE center), is now actually referenced as NIRSC both internally and externally/officially. They've removed the word FIRE because these resources have been made available to all-hazard incidents now, which include law, sar, disaster response (hurricanes tornados quakes floods zombies...). At the same time this occurred, they expanded the channel list up to 12, including the first four VHF IR pairs to help with that nationwide interop capability for a Katrina-like event. All the other hazards have looked at Boise NIFC and said, "wow, they got their stuff together, and there are warehouses full of toys that sit unused off-season and slow seasons, maybe we shouldn't reinvent the wheel and just expand off that existing near-perfect system..."
Just like CLEMARS in California, it'll take a long time to remove habit for some folks. Everyone knows "niff-see" but nobody says "nur-see" yet in the comm tents. Also, NIFC is one less alpha numeric on radio displays
.
Now to sit and wait for a LAWSCOPE to be created to cheerlead/support the law side of things, that FIRESCOPE has already solved decades ago...
