Under the LANDmark reorganisation from 2002, the group was redesignated as 101st Logistic Brigade and placed under Force Troops Command, but remained under operational command of the 3rd (UK) Mechanised Division still. Under the Army 2020 plan, the Brigade re-subordinated from HQ Force Troops Command to 3rd (United Kingdom) Division permanently on 1 December 2014.

Future
Under the Future Soldier programme, the brigade will be redesignated as the 101st Operational Sustainment Brigade. The brigade's headquarters will move to Imphal Barracks, York in future, and its units designated as 'Combat Support units'. The future role of the brigade has been described as follows: "101st Operational Sustainment Brigade will provide the 3rd Division's logistics and equipment support. It will include the Army's heavy equipment transport and powerpack repair capability; ensuring the armoured BCTs can deploy rapidly and sustain high intensity operations."
