Mobilising the Strategic Reserve for Next-Year Exercises
The Ministry of Defence (MoD) will conduct a nationwide mobilisation exercise next year to test how former regular service members—collectively known as the Strategic Reserve—can be contacted, called up, equipped and returned to uniform. The exercise is described by Armed Forces Minister Louise Sandher-Jones as the most significant test of the system in decades. It will evaluate recall effectiveness, engagement of reservists with specialist skills, and the speed at which Defence can access needed personnel.
Background & Context
The Strategic Reserve, separate from the roughly 32,000 active part-time reservists, consists of former regular personnel who retain a legal liability for recall. The 2025 Strategic Defence Review called for the Reserve to be “reinvigorated” and highlighted a lack of knowledge about where former personnel are and what skills they possess. Lessons from the prolonged war in Ukraine prompted senior defence leaders to rethink mobilisation of ex-regulars now in civilian jobs or retirement.
Key Figures & Groups
- Louise Sandher-Jones – Armed Forces Minister, former Army officer.
- Air Chief Marshal Sir Richard Knighton – Chief of the Defence Staff, warned of inadequate tracking of former personnel.
- Lt Gen Paul Griffiths – Commander Standing Joint Command, advocated expanding the recall pool.
Data & Statistics
- Strategic Reserve size: ~95,000 former service members.
- Active reservists: ~32,000 part-time volunteers.
- Specialist expertise in the Reserve: cyber, intelligence, medicine and communications.
- Regular Army strength: about 71,000 fully trained personnel, the smallest peacetime figure in more than two centuries. Recent recruitment modestly outpaced departures for the first time since 2021.
