On 28 April 2015 an event was hosted by the Army’s newly-established Centre for Historical Analysis and Conflict Research (CHACR). About 20 high-level delegates drawn from the military, academia, the civil service and the private sector came together in a closed forum to challenge established British Army thinking. The forum was held in the spirit of an objective and critical evaluation of the assumptions the Army makes about its defence engagement activities in support of the nation’s prosperity agenda. What follows is a synthesis of the participants’ discussions in break-out and plenary groups, all held under the Chatham House Rule.
