Spoke to a mate of mine who's on Sea Kings at Boulmer, and he reckons that the RAF guys have invested a lot of time and effort into Paramedic registration, after being advised by the Legal Beagles that to continue giving advanced medical treatment would become illegal. Quite what advanced is, I'm not sure. Still, they've employed some A+E consultant to run their training, and they all should all be registered by July.
I'm sure that if the military have done this, then the civvie guys will need to follow suit, as I'll bet the CG will want their crews to be able to offer the same treatments as their yellow hatted counterparts. Can't see the MCA accepting a loss in capability, or an illegal operation.
