Army 2020 Refine

As its name suggests, it was a "refinement" of Army 2020, an early 2010s reorganisation of the Army to be completed by 2020, originally conducted in light of the Strategic Defence and Security Review 2010.

The Strategic Defence and Security Review 2015 announced that the structure of the Reaction and Adaptable Forces would further change, in an evolution of the previous Army 2020 plan.

In a Defence Committee hearing, Chief of the General Staff Sir Nicholas Carter stated that "each of these [Strike] brigades will have two AJAX regiments and probably two Mechanised Infantry Vehicle (MIV) battalions as well".

[3] A December 2016 written statement[4] stated that the first Strike Brigade to form would consist of: Other units such as 1 Regiment RLC, 1 Close Support Battalion REME, 3 Medical Regiment and 21 Engineer Regiment would provide close support to this Strike Brigade.

A total of five Specialised Infantry battalions, around 300 personnel strong:[6][7] Several units were initially meant to be rationalised, with all manpower in those units being redeployed to other areas of the Army in its refined structure.
