At least in the 80s, the British Army used to do a lot of training on indoor ranges with sub-calibre simulators, which is a fancy term for rigging up an assault rifle to fire .22 longs. The trick was that you projected an exterior scene on a large screen made of multiple layers of randomly moving paper; the sound of firing gets picked up by a microphone and the backlit, multi-layer screen shows a little dot of light, which is where you hit. Because the paper is moving randomly, you never get the same hole through all the layers twice. (Or at least not until the paper really needs replacing.) This lets you do all sorts of live-fire training at realistically confusing targets without needing a lot of outside to do it in, something the Isle of the Mighty has in short supply if at all. It is possible that the picture, especially given the weird perspective and silly height of the fence, was taken in a facility like that, with a projected night sky on the wall. -- Graydon -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
