The Ministry of Defence (MoD) has announced that British Challenger 2 tanks stationed in Estonia as part of NATO's deterrence mission will be withdrawn and replaced by a new fleet of high-tech reconnaissance and attack drones. The decision marks a significant shift in how British forces reinforce NATO's eastern border with Russia and reflects lessons learned from the war in Ukraine, where drones have become the defining weapon while tanks have suffered heavy losses.
Transition to a Mobile Anti-Armour Force
From April next year, the British troops based in Estonia will transition from an armoured battlegroup to a "Mobile Anti-Armour Force." This new force will see the Challenger 2 tanks return home, replaced by advanced drones and "highly-mobile" vehicles. The MoD said the changes will allow the force to "deploy, disperse and demonstrate combat readiness more rapidly than a traditional armoured formation." The number of British soldiers in Estonia is also set to increase from about 800 to 1,200.
Enhanced Capabilities and Survivability
The MoD stated that the new force will have greater mobility, faster response to threats, and enhanced survivability through "increased dispersal, deception and adaptability." The upgrades are understood to include not only drones but also advanced weapons such as upgraded rocket launchers. Defence Secretary Dan Jarvis, who signed off on the plans alongside his Estonian counterpart in Tallinn, said: "More people, better mobility, and the latest tech means a more lethal and effective force, ready to fight and win alongside allies."
Strategic Context and Warnings
Britain has had a main battle tank squadron deployed in Estonia since 2017. The MoD said the changes "reflect the realities of modern conflict" while being tailored to the threats facing Estonia. NATO Secretary General Mark Rutte has warned that Russia could be ready to attack the alliance by 2030, with the Baltics widely seen as the most likely target. The Express understands that the decision has been in the works for around two years and is based on analysis that included wargaming exercises with Estonia.
Future of Challenger 2 Tanks
The Challenger 2s returning from Estonia will be retasked, while 148 of Britain's battle tank fleet are set to be upgraded to Challenger 3s. In Labour's long-awaited Defence Investment Plan, the party claimed that tanks "remain essential" to modern warfare, ensuring land forces can "seize or defend ground in all environments and conditions."
