9.5 We would envisage that the majority of joint or Defence organisations would be delivered by a 'lead Service', as many are now. This should minimise overheads, support the grain of delegation and single Service force generation, and foster a more joint approach by the single Services. The single Services should retain those capabilities that are core to their Services, to ensure that they maintain their overall integrity and coherence. As set out above, in the majority of cases the input generation of forces is better achieved on a single Service basis, except where the capability acts as an enabler across the environments.
