Sun, it is my understanding that the UK SRR stretches to 30W. Personally, I don't have a view whether this should be a military task or not. After all, littoral SAR is alread provided by charity (RNLI), the coastguard (increasingly so) and the military. My concern is that the UK doesn't actually have any significant capability (regardless of the uniforms worn) beyond 10W. My home nation (Eire) currently has more to offer and our particular bit of the Atlantic is so much smaller.
