Those aren't scanners, those are two way radios.
Federal govt requires approved radios for use by cooperators on Forest Service incidents and they are only approving new P25 radios.
it’s that way with any federal money for radios for anyone. If a local small town PD/FIRE/EMS service gets federal money for radios, the have to be p25 ready. They don’t have to use it, but be ready for it.
