Sorry, somewhat slow reply... MiniGunDiplomat's description of "Nav on Ops" is a classic indicator to me of the Helmand-myopia gripping the Army and the SH force. The GR4s in Afghanistan operate all over the country, supporting ISAF forces across the different RCs and provinces, and it is a source of great frustration to me that so many people, even RAF people, only think of Helmand when they think of Afghanistan. There still isn't much nav on ops though - the GPS/IN solution pretty much takes care of that side of business!
