Some 1,500 British troops from 4 Brigade have deployed to Estonia for Exercise Spring Storm, training alongside NATO members and partners within 25km of the Russian border.
The exercise, supported by Challenger 2 main battle tanks moved into theatre on heavy equipment transporters, was built around a battlegroup formed on the 2nd Battalion, the Royal Regiment of Scotland.
The battlegroup, we understand, was tasked with defending against an incursion by an aggressive neighbouring state across the border, operating in the south-easternmost part of Estonia where the training scenarios were conducted close to Russian territory.
The Ministry of Defence said the exercise demonstrated the deployment of NATO’s Forward Land Force, the framework under which the alliance stations multinational combat formations on its northern and eastern flanks. Imagery released from the exercise showed Challenger 2s being unloaded and manoeuvring under smoke during the training, conducted through the second half of May.

British troops have been deployed to Estonia since 2017 under Operation Cabrit, the UK’s contribution to NATO’s enhanced Forward Presence, which was established after Russia’s annexation of Crimea in 2014 to reassure allies on the alliance’s eastern edge. The UK leads the multinational battlegroup based at Tapa, and Estonia is among the Baltic states that share a land border with Russia and have pressed consistently for a visible allied military presence.
The Forward Land Force concept is really more of an evolution of that presence, following Russia’s full-scale invasion of Ukraine in 2022, NATO agreed to scale its eastern battlegroups up toward brigade strength where required, with framework nations committing additional forces held at readiness to reinforce them. For the United Kingdom, that has meant maintaining a standing presence in Estonia while earmarking a larger formation that can deploy to reinforce the country at speed, an arrangement that exercises such as Spring Storm are designed to rehearse.
Exercise Spring Storm, known in Estonian as Kevadtorm, is the Estonian Defence Forces’ principal annual field exercise, drawing in allied units alongside Estonian regulars, reservists and conscripts. Holding the training in the south-east of the country, close to the border, places it in the terrain that a defending force would have to hold in the event of an incursion, and tests the movement of heavy armour and the establishment of command posts under field conditions.













Wouldn’t it be good to get another 50+ CR3 tanks in the shed for 200+ as buffer stock to back up tank deployments and our allies on any North-South Eastern front and to follow up in force after all the drones have gone into action? Previous posts quoted at £5million each?
148 is little better than pointless, just another politically mandated MIC jobs for the boys procurement.
We should have decided if we actually required a MBT capability.
If the answer is yes, then its Abrams, Leppard or the South Korean tank, pick one and assemble it, so you have a scalable build.
CH3 is a cul de sac, a dead end with limited hull availability and zero possibly to scale up the fleet.
large tank force for the uk is pointless, to expemsive and we lack the other kit to build the regts around it. Its about time we woke up and accepted we are not a world power and we can not have it all. A arge Army is no good to us as we have no where to house them, we can not afford all the new kit or man power increases.
Deluded people who think any government will cut welfare etc to fund defence need to see reality, we must be good at some things, not below to average are every thing. Best we can do is have good navy, verygood GBAD, good Air force and small but very moden Army, increae the Army ok where will you put all the troops and kit? / how will you pay for it?
Let other do the land battle we should do war at sea and defence of the nation, whislt backiong up Allies with specail roles.
