Army
Undercover With British Snipers
Dozens of British Snipers from across the forces have been battling it out this week to be named the best in the military and earn themselves the chance to represent their country overseas.
They have also been pitting their skills against international teams from Canada, America and Denmark.
Kaija Larke has been along to Salisbury Plain to see what it takes to be the best, and find out how operations have shaped the way they do things.
