Testing Times For British Snipers
Over the decades, snipers have been used by the military to work covertly, often deep into enemy territory.
Keeping up their marksmanship and accuracy is a constant task, which is why - every year - competitions are held across the British Armed Forces.
Ali Gibson has been to Barry Buddon ranges near Dundee in Scotland, to visit the snipers of 3rd UK Armoured Division.
