Video from a readiness exercise held in March 2015 on the Western edge of Salisbury Plain military training area. While a full-blown military exercise takes place with Tornado GR4 bombers, Apache attack helicopters, Challenger battle tanks and thousands of troops, the Army positions their AS90 mobile tracked guns on the edge of Westbury right by the public track for fire-missions into the battlespace five miles away.

This video was taken of those Braveheart Army guns in action. I have altered the audio to match the visual gun-fire for better effect. Even at a few hundred meters the sounds of gunfire lag behind the visual event itself.
