The civil ladies and gents do it differently. Currently, they are not formally tasked to do the same as the military. When they are, SAR-H, they will be trained accordingly. End of.
It will be interesting to see how the training regime does develop, the MCA are the current 'client' and money is quite tight. As time equals money, I'm not sure how much extra training, if any, the MCA would be prepared to swallow. Would you then end up with a 'harmonised' service with varying levels of capability depending upon which uniform you wear?
