The deployment to Estonia is also likely to include armoured Infantry, Warrior armoured fighting vehicles, unmanned aircraft and Challenger 2 Main Battle Tanks.
Defence Secretary Michael Fallon confirmed the UK will be sending 800 personnel to Estonia, with France and Denmark contributing further troops.
“We will work harder for our alliances and partnerships when we leave the EU because we are committed to the defence of our continent.
That’s why we are moving troops to the NATO mission in Estonia, a company to Poland and RAF Typhoon fighter aircraft to the Black Sea.”
The M270 is an armoured, self-propelled, multiple rocket launcher; a type of rocket artillery.
Since the first M270s were delivered to the US Army in 1983, the MLRS has been adopted by several NATO countries.
Some 1,300 M270 systems have been manufactured in the United States and in Europe, along with more than 700,000 rockets. The production of the M270 ended in 2003, when a last batch was delivered to the Egyptian Army.
The Guided Multiple Launch Rocket System has twice the range of other artillery systems used by the British Army.
Within the British military, a common nickname is “Grid Square Removal System”, a play on the initialism GSRS (from the older General Support Rocket System).
With the adoption of the new M30 GPS guided rocket, it is now being referred to as the “70 kilometer sniper rifle”. During the 1991 Gulf War, the Iraqis referred to the small M77 submunitions rockets as the “Steel Rain”.
The system can fire up to 12 rockets in less than 60 seconds.
