On 29 October 2015 an event was hosted by the Army’s Centre for Historical Analysis and Conflict Research (CHACR) in which approximately 50 high-level delegates drawn from the Army, the private sector, the civil service and academia 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 the delivery of the Whole Force Approach (WFA). What follows is a synthesis of the participants’ discussions in break-out and plenary groups, all held under the Chatham House Rule.
