The Cyp Government allow only 84 to be permanently based in Cyprus because it is dual-hatted with its UN support role (note the blue UN band round the fuselage). As for going 'oop north', I would imagine they would continue do so in both roles. Witness a couple of years ago they spent a huge amount of time with rainmaker fighting a major fire west of Kyrenia - the Cyp Authorities would be unlikely to refuse help from 84 even if they had a fire-fighting capability of their own.. .. .Also, SAR crosses international boundaries, and additionally 84 enjoys an enviable reputation with the Cypriot authorities for their fire-fighting & SAR work, which have saved many Cypriot lives and many villages, all at no cost to their Government. Therefore, whatever the Cyp Gov put in place to fulfill their commitment, it is likely that the 2 SAR forces will work closely together like all SAR forces worldwide.
