I don't think it's much of a security issue; however I thought that it may be a goer due to the high level of recruiting done lately, much more than any other service of late in N.I. Creating a reserve would be the logical step.
Yeah, about time an RMR unit came to belfast, stick it in with the RNR Culdrose ship. Theres a whole little area there for circuit training and drill (plus a big enough deck on top if it's really bad weather). Plus the Marines took me out on a rigid from there once round Belfast loch for a spin. Good fun so it was.
