The scope of the holdings is vast, from high level defence policy and strategic planning as, for example, in the papers of Field Marshal Alan Brooke, 1st Viscount Alanbrooke and General Hastings Lionel Ismay, 1st Baron Ismay down to the command of individual units in the field. The Second Boer War is strongly represented and subsequently almost every major campaign in which British troops have fought, including the Korean and Falklands Wars and the Gulf Crisis; the latter two are covered by contemporary interview transcripts.
