In early 1971 they wre shutting down FEAF. To this end the Marine Section was shuttling to the China Rock range with loads of ammuntion, tools etc and dumping it at sea. Then the Marine Section folded and there was a problem if getting rid of all this ammunition. A truckload of it arrived at the Squadron and we were told to fire it off from our Whirlwind 10s and dump what was left over. A Whirlwind had two GMPG mounts but but for this we only used the one at the main door and to give something to aim at we took the now redundant SAR dummy and let him sunbathe on the rock.
It took all day. We had three aircraft shuttling and every body was having a go. The crewmen, the squadron's regiment, ground crew, our clerk and all the squadron pilots. We had two spare barrels in each aircraft because after a couple of boxes the airstream on one side of the barrel causes it to bend so it has to come off to cool down.
Sighting was easy; it was 2/1 ball/tracer and you could work onto the rock using the splashes in the sea. It was a great day that used loads of HM's money and at the end the day the dummy was recovered and brought back to Changi.
There were two holes in him; one probably a ricochet.
