The story of the British Army's Household Division from 1969 to 2023. It is the biography of a family of three generations of soldiers who have served Crown and Country during a period of significant social and geostrategic change. The story of the British Army’s Household Division from 1969 to 2023 is one of three generations of soldiers who have served Crown and Country during a period of significant social and geostrategic change. It is the story of a family of seven regiments that symbolise the Union of Great Britain and Northern Ireland, Septem juncta in uno: The Life Guards, The Blues and Royals, Grenadier, Coldstream, Scots, Irish and Welsh Guards. The Guards established an ascendancy in the Peninsular War and at the Battle of Waterloo, and have never truly faltered since. They have managed this by changing when change was needed. Over the last 50 years, the Household Division has been at the centre of almost every major operation conducted by the British Army: Northern Ireland, the Falklands, the Balkans, Iraq and Afghanistan. At the same time, the Household Division is a national institution, admired by the public through its mastery of ceremonial and pageantry, and the magnificent hour that is Trooping the Colour. The professionalism and self-discipline of the individual Guardsmen and Troopers are what ensures both their exemplary performance on operations and their high standards of state ceremonial and public duties. Those Must Be The Guards illustrates both roles through the experiences of those who have served in the Household Division over the past half-century.
