The Times assessed how long the British army could last instead of the Ukrainian one.

About 10,000 active sailors, soldiers, and pilots of the British army have been deemed unfit for service due to health problems. Another approximately 15,000 military personnel could be deployed, but with certain medical restrictions.

The Times reported that more than one-fifth of the army's personnel cannot participate in combat operations without limitations. British Veterans Affairs Minister Al Karns emphasized this.

In total, 16,335 soldiers are either unable to be deployed for medical reasons or can be deployed with restrictions. This constitutes 23% of the total army strength of 71,340 service members. Only 55,005 soldiers are fully prepared for deployment.

In the Royal Navy, 2,922 sailors cannot go to sea, and 2,363 have limited fitness for service.

The highest rate of unfit personnel is observed in the Royal Air Force, where 3,721 out of 27,969 are unfit.

Al Karns has previously noted that the British army could suffer significant losses if faced with adversaries like Russia. He emphasized that with only 55,000 regular soldiers and Russian losses of about 1,500 per day in Ukraine, British troops could be effectively destroyed in just a month.
