Britain will begin the process of moving high-precision long-range missiles to Estonia next year amid fears Russian President Vladimir Putin could be making plans to invade the country.
The 200lb long-range rockets, known as Guided Multiple Launch Rocket Systems (GMLRS), can fire up to 12 missiles per minute, and can blow up a target over a range of 45 miles.
The warheads are fitted with GPS which allows them to seek out targets from a distance.
The missiles have already been used in a warzone. From 2007, they were deployed in Afghanistan to target Taliban bunkers, with a total of 410 missiles being fired at tunnel networks in Helmand Province.
