The article indicates that it's "used for test firing at artillery ranges that are directly on the urban fringe without creating any inconvenience to the nearby civilian population due to noise." Yeah. Right. Minimize the muzzle blast so as not to disturb anyone. As if the sound of incoming rounds exploding within the impact area doesn't piss off the locals.

Joseph I live on Salisbury plain and next to an RAF base, and so the sounds of war are common around here, no different than birdsong. you become so use to the sounds you actually only really notice when they are not there. The only person I have heard of that is supposed to have complained, was Sting when they wanted to base the flight refuelling aircraft at the base and which would be flying over the top of his house.
