A new 878 Institute paper says four armoured infantry battalions face a gap between Warrior leaving service and Boxer arriving in numbers, and wants the shelved Warrior upgrade revived to bridge it. The first of eight recommendations in Britain’s Military Deterrence Gaps is that the Government halt the decommissioning of the Warrior Infantry Fighting Vehicle and fund the Warrior Capability Programme, which was part funded and then rejected. On the paper’s reading that “will leave a significant capability gap”, with Warrior phased out and no operational replacement for the Army’s four armoured infantry battalions. General The Lord Dannatt, who wrote the foreword, goes further, calling for an Ajax programme “that should be scrapped in favour of upgrading the WARRIOR infantry fighting vehicles”. The Government has previously ruled out retaining Warrior in service, a decision this publication reported in 2025 and which the paper cites.
