Question to the Ministry of Defence:

To ask the Secretary of State for Defence, with reference to page 109 of the Strategic Defence Review 2025, what (a) units and (b) formations comprise the UK contribution to the Advanced Reaction force.

Advanced Forces are forces already in place around the world that provide positional advantage. These include the UK’s contribution to Forward Land Forces in Estonia and Poland, Land Special Operations Forces deployed as part of our global network, the Brunei Task Force, and Cyprus Resident Battalions.

Reaction Forces are designed for speed, to react quickly to crisis. These include Defence’s Global Response Force, 16 Air Assault Brigade, and the NATO Allied Reaction Force (Land).
