THE MISSIONS OF THE ARMED FORCES
Defence policy requires the provision of forces with a high degree of military effectiveness, at sufficient readiness and with a clear sense of purpose, for conflict prevention, crisis management and combat operations. Their demonstrable capability, conventional and nuclear, is intended to act as an effective deterrent to a potential aggressor, both in peacetime and crisis. They must be able to undertake a range of Military Tasks to fulfil the Missions set out below, matched to changing strategic circumstances.
A: Peacetime Security: To provide forces needed in peacetime to ensure the protection and security of the United Kingdom, to assist as required with the evacuation of British nationals overseas, and to afford Military Aid to the Civil Authorities in the United Kingdom, including Military Aid to the Civil Power, Military Aid to Other Government Departments and Military Aid to the Civil Community.
B: Security of the Overseas Territories: To provide forces to meet any challenges to the external security of a British Overseas Territory (including overseas possessions and the Sovereign Base Areas) or to assist the civil authorities in meeting a challenge to internal security. (An amendment to legislation in due course will formalise the change of title from "Dependent Territories" to "Overseas Territories".)
C: Defence Diplomacy: To provide forces to meet the varied activities undertaken by the Ministry of Defence to dispel hostility, build and maintain trust, and assist in the development of democratically accountable armed forces (thereby making a significant contribution to conflict prevention and resolution).
D: Support to Wider British Interests: To provide forces to conduct activities to promote British interests, influence and standing abroad.
E: Peace Support and Humanitarian Operations: To contribute forces to operations other than war in support of British interests and international order and humanitarian principles, the latter most likely under UN auspices.
F: Regional Conflict Outside the NATO Area: To contribute forces for a regional conflict (but not an attack on NATO or one of its members) which, if unchecked, could adversely affect European security, or which could pose a serious threat to British interests elsewhere, or to international security. Operations are usually under UN or Organisation for Security Co-operation in Europe auspices.
G: Regional Conflict Inside the NATO Area: To provide forces needed to respond to a regional crisis or conflict involving a NATO ally who calls for assistance under Article 5 of the Washington Treaty.
H: Strategic Attack on NATO: To provide, within the expected warning and readiness preparation times, the forces required to counter a strategic attack against NATO.
