I think the version I've seen in WW2 manuals has outstretched spread fingers, but I have heard it given as knuckles too
Used both knuckles and spread fingers as an OP Ack to calculate the left/right corrections for fall of shot, although we measured it Mils not degrees. Converted the angle to metres by subtension. " 1 mil at 1,000 = 1 metre", that is for every mil measured it equalled 1 metre for every 1,000 metres between you and the target. E.G. round lands 10 mils to the right of the target which is 3,000 metres away - 10 (mils) x 3(000)(metres) = 30 metres. Order to guns Left two five (we worked in multples of 25 metres). Derek
From memory, the diagrams in the ACF manual c1980 were exactly the same as those in Infantry Section Leading between the wars. Still, if it ain't broke...
Thanks for reminding me, I had forgotten the details of all this. Just dragged out my old file. I passed my Cert A in 1961. Went back in 1981 and did my Gallery Range Course in 1984. So its a long time ago. I doubt that I could walk the length of a range now. Had some good times with my old mates most of whom had joined up as Regulars. Why I did it for so long I will never know. I left the cadets in 1969 joining a rock band and left as an adult in 1998 to do do exactly the same thing, with pretty well the same people. Guess I'm just a crazy mixed up kid with nothing better to do.
