10.6 In line with our drive to clarify and simplify the roles and responsibilities of both the single Services and PJHQ, we believe that, whilst force generation should be the responsibility of the single Services, force employment should be conducted on a joint basis through PJHQ unless there are exceptional reasons of operational effectiveness to do otherwise. Application of this principle would ensure full exploitation of the operational focus, connectivity, relationships and facilities of PJHQ. The Department should consider whether the operations that do not currently follow this principle, notably maritime operations, including the deterrent, security of UK airspace and UK Resilience, should continue to be led by the single Services.
