Talk: Rise & Fall of the British Army

About this event

The Rise & Fall of the British Army In his new book The Rise and Fall of the British Army, 1975–2025, Ben Barry analyses how the British Army evolved over the last half century. He shows how the Army’s combat capability increased throughout the 1980s in the face of a prospective war with the Soviet Union. The Army was tested on operations from Northern Ireland, the Falklands War, the 1991 Gulf War, through the Balkans and Sierra Leone to Afghanistan in 2001 and the 2003 invasion of Iraq. There followed two decades of descent from this high plateau of military success. Mistakes made in Iraq and Afghanistan led to a decline in support for military deployments. Cuts to defence funding and botched equipment procurements left the British Army of 2025 less than half the size of that of 1975, with much fighting equipment either obsolete or approaching obsolescence. There are lessons for the future from this half century of combat, continuity and change. The book identifies success factors for strategic leadership, innovation, adaptation and Army change programmes, as well as lessons from the Cold War relevant to the Army’s challenging new role in NATO. Brigadier Ben Barry Ben Barry is a Associate Fellow, Defence and Military Analysis. He joined the IISS in 2010, before which he served in the British Army.
