Unfortunately, I don't know that we can know that there is such a clear distinction. Hezbollah also provides many other governmental services, so I don't think we can totally rule out the possibility that, e.g., ambulances could be driven by Hezbollah members who use these radios.
Hezbollah is not the Lebanese military. They are a paramilitary gang, comparable to the cartels in Mexico, that gained too much strength for the actual Lebanese military to deal with. Mostly because Iran trained fighters and sent weapons.
Actually a better example than the cartels might be the CIA sponsored paramilitaries in South America. Except Hezbollah is sponsored by Iran obviously.
