Next, it might enable better comprehension of a Gunner Surveyor’s role if I explained there were the two principle methods employed by a Locating Battery RA, to locate an enemy’s artillery, one Flash Spotting, the other Sound Ranging. The former was difficult to employ satisfactorily in Korea because of the terrain and the nature of the static war that developed but Sound Ranging could and did produce meaningful results. That was to locate, and by counter fire kill the enemy and destroy Korean and Chinese guns and mortars.
(For details about my Sound Ranging and the Flash Spotting of John Flann go to http://nigelef.tripod.com/tgtacqcb.htm. This is a most interesting treatise on the development of the science of gunnery itself and particularly relevant in our cases: counter bombardment fire through the ages.)
