Brocklesby deals with 'very real threat' off besieged Misrata The mine appears to be a derivative of an old Soviet era PDY-3M contact mine. This is much less sophisticated than the 20 export versions of Soviet multiple-influence ground mines laid by the Libyan RO-RO ferry Ghat in the Red Sea in July 1984. 19 of these mines were actuated by transiting merchant ships but they were not optimised against such large, noisy targets so they exploded too far away to cause any serious damage. This little-remembered mine clearance operation was code-named Operation HARLING. For their actions which included the detection, rendering safe and recovery of one of these mines, Lt Cdr Nigel 'Bernie' Bruen DSC RN (the CO of HMS Gavinton) was appointed an MBE and WO(Diver) Terry Settle MBE BEM (Fleet Clearance Diving Team) was awarded the Queen's Gallantry Medal (QGM).
