Around 8,000 British soldiers are due to be sent to eastern Europe to take part in military exercises designed to combat Russian aggression.
The deployment – which is one of the largest to take place since the Cold War – will see troops placed in countries from Finland to North Macedonia.
Dozens of tanks and more than 100 armoured fighting vehicles will also be sent to the locations this summer under plans that have been bolstered since the war in Ukraine began.

The armed forces will be joined by tens of thousands of troops from NATO and Joint Expeditionary Force allies, which include the likes of Denmark, Iceland and Norway.
The Ministry of Defence (MoD) said the planned exercises will enhance the ability of UK and Finnish troops to work alongside each other, “deterring Russian aggression in Scandinavia and the Baltic states”.

Defence Secretary Ben Wallace said the move will show “solidarity and strength”.

“Operating across Europe, the British Army will stand alongside partners, combining our capabilities and shared values, promoting peace and security.”
The UK deployment is expected to build to a peak of around 8,000 personnel operating in mainland Europe between April and June.
Some of the exercises are set to include parachute drops, helicopter-borne air assaults Challenger 2 tanks.
The drills aim to “showcase the extent and significance of the British Army’s contribution to the defence of Europe”, the MoD additional.
Commander Field Army Lieutenant General Ralph Wooddisse explained: “The UK makes a meaningful contribution to the defence of Europe and the deterrence of Russian aggression. The British Army’s series of exercises is basic to both.
“The extent of the deployment, coupled with the professionalism, training and agility of the British Army, will deter aggression at a extent not seen in Europe this century.”
Exercises alongside American troops are also taking place in Poland.
Western powers are attempting to show their sustain for Ukraine is not waning
The Ministry of Defence says this is one of the largest military deployments since the Cold War and they are blunt that this is about showing solidarity and strength – no prizes for guessing who the intended audience is.
These exercises are to deter Russian aggression, to deter Vladimir Putin from entering a new conflict.
We understand that the military exercises the UK is involved in will peak between now and June, with 8,000 British army troops involved.
But if you count all of the troops from all of the NATO and the Joint Expeditionary Force countries together, then we are talking about tens of thousands of armed forces personnel.
Of course this comes as Joe Biden has asked Congress for $33bn (£27bn) for military, economic, and humanitarian assistance for Ukraine.
Western powers here are attempting to show their sustain is not waning as the conflict enters its third month.
