The British Army is headed by the Chief of the General Staff and his General Staff who are based at the Ministry of Defence in London

The Commander-in-Chief Land Forces is based in Headquarters Land Forces and reports directly to the Chief of the General Staff to deliver forces that are properly trained and equipped to sustain current operations.

This is achieved through four subordinate commands:

Field Army (Fd Army)
A 3 star command commanded by Commander Field Army (CFA). Responsible for generating and preparing forces for current and contingency operations in order to deliver operational success.

Personnel and Support Command (PSC)
A 3 star command commanded by the Adjutant General (AG). Delivers personnel policies, plans and services and the Firm Base to support the generation of operational capability.

Force Development and Training Command (FDT Comd)
A 3 star command commanded by Commander Force Development and Training. Responsible for individual and collective training, and concepts and doctrine, to optimise the delivery of Army capability in order to ensure success on operations, now and in the future.

Joint Helicopter Command (JHC)
A 2 star command formed in 1999 to bring together under one command the battlefield helicopters of the Royal Navy, Army and Royal Air Force.

The Army command structure is hierachical, having controlled groupings of units based around Divisions and their Brigades.

Within these Brigades are Major Units, regiment or battalion-sized and Minor Units, smaller company sized sub-units or platoons.

All units within the service are either Regular (full-time) or Territorial Army (part-time), or a combination with sub-units of each type.
