The key base_function=* may be used to indicate the main function of a military base or facility e.g. whether it houses Operational units, a Headquarters, a Training facility, or a Logistics area. It would be added to military=base.
The same tagging should be used regardless of whether the facility is for Regular, full-time forces, or part-time, volunteer Reserve forces. Where multiple services use the same facility, and the name of the facility does not make clear which service runs it, the tag should be designated to the largest service using that facility, for example an Operational base that also houses a Training School would be shown as base_function=operational.
This tag may also be used for facilities operated by armed Coast Guards, i.e. the military / para-military force intended for protection of a country's coastal waters against enemy military forces, as well as civil threats such as smugglers, terrorists etc.
It also applies to stand-alone military buildings such as recruitment offices.
