The UK government is planning to increase the age of for former military personnel liable to be recalled to service. The British defence ministry has said it will introduce new measures through the Armed Forces Bill aimed at expanding the pool of former military personnel who can be recalled in times of crisis. The changes are intended to strengthen the Strategic Reserve, which consists of former service members who retain an Ex-Regular or Recall Reserve liability after leaving active duty.

According to the Ministry of Defence, the bill proposes several adjustments to recall rules affecting Regular and Volunteer Reserve personnel once they leave service. These measures are designed to ensure that Defence can access a wider range of skills and experience if required during periods of heightened tension or conflict.

Under the proposed legislation, the maximum age for recall would increase from 55 to 65. The bill would also align the duration of recall liability across the Army, Royal Navy, and Royal Air Force. In addition, the threshold for recall would be lowered so that personnel could be called up for “warlike preparations,” rather than only in cases of “national danger, great emergency or attack on the UK,” as is currently the case.

The Strategic Reserve includes former service members with experience in both military and civilian roles. The Ministry of Defence said this group provides expertise in areas such as cyber operations, intelligence, medicine, and communications. The new measures are intended to give Defence greater flexibility to draw on these capabilities during a transition to war or other national emergencies.

Commander Standing Joint Command, Lieutenant General Paul Griffiths, said, “As the threat to our nation grows, we must ensure our Armed Forces can draw on the numbers and skills required to meet it. I fully support these measures, which will give us the widest possible pool of experienced personnel to call upon in times of crisis.

“Our Strategic Reserve represents a wealth of expertise built over years of military and civilian experience – from cyber and intelligence to medicine and communications. These reforms will allow us to mobilise that talent rapidly when it matters most, strengthening our readiness and aligning with a similar approach many NATO forces are taking to bolster their own resilience,” he added.

The Ministry of Defence said the approach reflects similar steps taken by NATO allies, including the United States, France, Germany, and Poland, to place greater emphasis on reserve forces. It also draws on lessons from Ukraine’s mobilisation of reservists following Russia’s invasion.

In 2024, more than one in five personnel involved in training Ukrainian forces under the British-led Operation INTERFLEX were reservists, highlighting the role reserve forces already play in overseas military activity.
