I removed the HM Coastguard from the "Royal Navy" parent category, after discussion with colleagues responsible for categorisation in England, Ireland, Scotland and Wales, as it seemed to us that the coastguard service has been civilian for most of its existence: either under the UK Treasury or the Department for Transport. So it is currently located as an agency of the United Kingdom. However, there is no "United Kingdom" Project, so if the category is going to fall within the purview of a Project, that would need to be "Military and War". If that Project doesn't want it, it would need to be managed by the ad hoc liaison group of the categorisation coordinators of the England, Ireland, Scotland and Wales Projects.
