The British Army is currently undergoing major restructuring. While some titles will not change, some structures and posts are constantly evolving.
The Army consists of the general staff and a deployable field army.
The Chief of General Staff, based in Andover, heads a single army staff and exercises command of the Army through three subordinate commanders: Commander Land Forces (CLF), Commander Force Development and Training (FDT) and the Adjutant General (AG).
The hierarchical command structure is organised as follows:
- Corps: this is formed of two or more divisions, and can constitute as many as 50,000 personnel.
- Divisions: formed of three or four brigades, as many as 20,000 personnel, commanded by a major-general.
- Brigade: three or four battalion-sized units, numbering around 5,000 personnel, and commanded by a brigadier.
