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.
