The UK is broadening the group of former service personnel who could be called back into service up to age 65, while the US is gearing up to automatically enrol young men into its existing Selective Service draft pool.

This stark contrast has sparked renewed discussion about military readiness on both sides of the pond. The UK changes only apply to a select group of already-trained ex-regular veterans. Meanwhile, in the US, the Trump administration is putting into action a change approved in the 2026 National Defense Authorization Act (signed by the President in December 2025). Neither policy equates to conscription.

From December 2026, eligible men aged 18 to 26 will be automatically registered with the Selective Service System through integration with federal data sources.

This policy aims to streamline the long-standing legal requirement for young men to register in case a draft is ever needed – no draft is currently in place, and there hasn’t been one since the Vietnam era.

In the UK, the Labour government’s Armed Forces Bill – introduced to Parliament in January 2026 – raises the maximum recall age for the strategic reserve (primarily ex-regular veterans) from 55 to 65, reports the Express.

These changes, set to come into effect in spring 2027, will also permit reservists to be mobilised for “warlike preparations” rather than solely in instances of direct national emergency or attack on the UK. Those who have already left the military will not be affected unless they choose to opt in.

The Ministry of Defence claims the move will harness “a wealth of expertise” from veterans with skills in fields such as cyber, intelligence, medicine and communications.

However, critics have labelled it as largely symbolic “political gesturing” that fails to tackle deeper recruitment and retention issues within the regular forces.

Former Defence Secretary Michael Fallon, speaking on April 8, 2026 during a chat with the Latika Takes podcast, advocated for a more ambitious strategy. He proposed a Nordic-style competitive national service for younger individuals, referring to it as “a badge of honour”.

Mr Fallon stated: “I’d like to see us adopt some form as the Nordics have of competitive national service, where it’s a badge of honour to get selected for it.

“You set a certain number of places and open up a competition for them, and within a couple of years, you find in the Nordics – and this is something employers absolutely valued – people fought to get places on the scheme.”

He conceded that more could have been done to bolster UK defences during the later years of the previous Conservative government.

These two developments are separate policy adjustments rather than new mass conscription schemes. The UK measure only applies to a limited group of already-trained ex-regulars (estimated strategic reserve pool of around 95,000), while the US change automates existing registration obligations without introducing compulsory service.

Both actions occur amidst persistent NATO pressure to enhance European defence capabilities in light of global tensions.
