The British Army is set to adopt a new military strategy dubbed “20-40-40,” placing greater emphasis on autonomous warfare and drone technology. The reforms, part of a strategic defence review reported by The Times, UK, reflect key lessons learned from the war in Ukraine.
Under the new doctrine, tanks, armoured vehicles, and attack helicopters will no longer spearhead attacks. Instead, they will enter combat only after an initial wave of drones has engaged the enemy. This approach is intended to increase lethality while preserving the lives of troops.
A Ministry of Defence source involved in the review said, “It is about pairing the old existing heavy metal with the new and making the army more lethal.” The review has been nearly a year in development and marks a significant departure from traditional tactics.
What “20-40-40” Means
The new strategy breaks down military capabilities into three categories:
- 20%: Traditional heavy equipment such as Challenger 3 tanks, which will be deployed later in the fight and from further distances.
- 40%: “Single-use” munitions like kamikaze drones and artillery shells, designed to strike once and explode on impact.
- 40%: Reusable autonomous systems, including high-end reconnaissance and strike drones like the MQ-9 Reaper, that can return for multiple missions.
This mix is aimed at maximizing operational impact while minimizing the exposure of soldiers on the front lines.
Lessons from Ukraine
The conflict in Ukraine has profoundly influenced the British Army’s pivot toward autonomy. Ukrainian forces have demonstrated the devastating effectiveness of drones in countering traditional Russian armour, forcing the Russian military to adapt by deploying motorbike units that can better evade drone surveillance and strikes.
Andriy Zagorodnyuk, a former Ukrainian defence minister, told The Times that Ukraine’s front line is now “completely transparent and completely controlled by drones on both sides,” reinforcing the need for digital dominance in modern warfare.
Preparing for a New Era
Unlike previous defence reviews focused on budget cuts, this one emphasizes enhancement—optimizing existing resources through cutting-edge technologies like AI, autonomous systems, and drone warfare.
Ukraine’s deputy defence minister, Kateryna Chernohorenko, also revealed that her ministry is developing a digital training platform to share up-to-date battlefield tactics with allies, including the UK. The app is part of a broader effort to prepare European forces should tensions with Russia escalate further.
