Fantastic bunch and very skilled. There are 31 worldwide and although they will spend a fair proportion of their time in Marchwood (17 Port & Maritime Regt RLC) there are posts in Cyprus (hopefully to remain post PJHQ review), the Falklands and Kiel yacht club. They also support SAS on various exercises and there is some work ongoing to provide the same sort of deployed support to SBS. There was some work looking to implant them into the REME Bns as a Metalsmith for 6m or so but I'm not sure if that has progressed at all. Oh, and they will deploy with the parent Regt whenever it goes somewhere - 6 or 7 of the lads have just finished a 6m tour in Kabul.
