Don't forget Gramps, that on SH we also had a secondary role as SAR in certain areas of operations. Certainly during Ops in NI. The Chinook fleet also helped in recovery post the Air India crash off SW Ireland. So chaps a possible inclusion in your fight to keep the rate you're on at present. Of course you will be pitted against the role of the WSOp on Voyager, and the Strat/Tac FW disciplines.
