Chief of the General Staff (United Kingdom)

The Chief of the General Staff (CGS) is the professional head of the Army, with responsibility for developing and generating military capability from an integrated Army (Regular and Reserve) and for maintaining the fighting effectiveness, efficiency and morale of the Service. The CGS reports to the Chief of the Defence Staff (CDS) and, as a Service COS, has a right of direct access to the Secretary of State and the Prime Minister. The CGS is a member of the Defence Council and the Army Board, the Armed Forces Committee, the Chiefs of Staff Committee and the Senior Appointments Committee. Responsible for:

• Maintains the institutional health of the Army by exercising Full Command responsibility for all Army personnel
• Ensures the efficient and effective governance of the service
• Chairs the executive committee of the Army Board and the Army Command Group
• Contributes to the conduct of defence higher level business, with a particular responsibility for providing specialist advice on Army matters
• Develops future Army capability within the context of Defence strategic direction and resource allocation
• Leads the senior management team of the British Army

The title was also used for five years between the demise of the Commander-in-Chief of the Forces in 1904 and the introduction of Chief of the Imperial General Staff in 1909. The post was then held by General Sir Neville Lyttelton and, briefly, by Field Marshal Sir William Nicholson.

Throughout the existence of the post the Chief of the General Staff has been the First Military Member of the Army Board.

The Chief was responsible for commanding the entire British Army. During the Second World War, General Brooke focused on grand strategy, and his relationships, through the Combined Chiefs of Staff with his American counterparts. He was also responsible for the appointment and evaluation of senior commanders, allocation of manpower and equipment, and the organisation of tactical air forces in support of land operations of field commanders; he also had primary responsibility for supervising the military operations of the Free French, Polish, Dutch, Belgian, and Czech units reporting to their governments in exile in London. Brooke vigorously allocated responsibilities to his deputies, and despite the traditional historical distrust that had existed between the military and the political side of the War Office, he got along quite well with his counterpart, the Secretary of State for War, first David Margesson and later, Sir James Grigg.
