Training areas for rescue organisations

We had a discussion about emergency services before Initial discussion: Possible new way of mapping emergency service areas & locations
The problem with disaster_response= as a feature is you prevent it from being able to be used as an attribute for emergency=disaster_response if needed. This consequence is seen in amenity=police from police= features.
Then you have to invent a set of =academy , =barracks , =helicopter_unit , =offices , =storage , and =training_area for every service. Results in many =training_area for each service, iedisaster_response=training_area , fire*=training_area , water_rescue=training_area , mountain_rescue=training_area , etc . There’s a further complication if different services share a facility.
Compare with how there’s no army= / navy= / air_force= =training_area , but only military=training_area one unified. Then military_service= for the service.
There are a few ideas that could be used for all emergency services. It can still be improved if emergency= is not the best. emergency=training_area | Tags | OpenStreetMap Taginfo
