As of December 2024, the UK Ministry of Defence (MoD) reports that 99,560 personnel are fully deployable, while 14,350 have limited deployability and 13,522 are medically not deployable.

Approximately 90% of service personnel are deployable, with ongoing efforts aimed at providing medical care and support for recovery and rehabilitation.

Former Armed Forces Minister James Heappey expressed concern that many non-deployable personnel may be unfit due to missed dental check-ups.

The Prime Minister has committed to a £2.9 billion increase in the defence budget for the coming year, aiming to reach 2.5% of GDP on defence by spring.

Defence Secretary John Healey emphasized the UK's commitment to increasing support for Ukraine during this critical period.

Speculation has arisen regarding the UK's potential deployment of troops to Ukraine for training, following discussions between Prime Minister Sir Keir Starmer and Ukrainian President Volodymyr Zelensky.

Over 10,000 members of the UK armed forces are classified as 'not medically deployable', highlighting significant challenges within the ranks.

MoD statistics from April 2024 reveal that all military branches are below their target strength for the first time, with the Army 1% short, the Royal Navy and Royal Marines 5%, and the RAF 10%.

Overall, Britain's Armed Forces are currently 5,440 personnel (1%) below their target size despite ongoing recruitment efforts.

The MoD is focusing on improving personnel welfare through measures such as pay raises, retention payments, and investment in military housing.

Personnel with medical conditions undergo assessments by a medical board to determine their deployability status, which can be temporary or permanent.

Heappey warned that in the event of war with Russia, the British Army could face severe losses within six months, advocating for plans to mobilize and train additional volunteers.
