The British Army recently took over Salisbury Plain for the Armoured Combat Power Demonstration (ACPD). Led by the 3rd (UK) Division, known as the Iron Division, the event was a clear look at the Army’s new strategy for modern war.
The 20-40-40 Rule
Major General Olly Brown (GOC 3rd UK Division) broke down the “Future Fighting Force” into a simple three-part formula. The goal is to move away from just having a few expensive tanks and move toward a mix of tech:
- 20% Survivable: These are the heavy hitters, such as the armoured vehicles used to carry soldiers. They are built to take a hit and keep the crew safe.
- 40% Attritable: These are mid-range robotic systems and high-end drones. They are “disposable” enough that losing them isn’t a disaster, but sophisticated enough to do serious damage.
- 40% Consumable: These are low-cost, “one-way” drones and loitering munitions. The Army wants to use these in massive numbers to overwhelm an enemy.
Soldiers and Robots Working Together
The demonstration showed that the future isn’t just about robots replacing humans, but humans controlling a swarm of tech.
Industry partners showed off autonomous vehicles that can carry supplies or scout ahead, keeping soldiers out of the “red zone.” Everything is linked by a “Digital Backbone,” allowing data to flow from a drone directly to a tank commander’s screen.
The Goal: Double the Lethality
General Sir Roly Walker (Chief of the General Staff) has set a hard target: double the Army’s fighting power within three years. This Expo proved that the Army isn’t just waiting for new equipment to arrive; they are changing how they fight right now. By mixing heavy armour with masses of drones, the Iron Division intends to be “harder to find and harder to defeat.”
What do you think of the 20-40-40 split? Is more “disposable” tech the right move for a smaller Army? Let us know in the comments.
