Options for Change was a restructuring of the British Armed Forces in summer 1990 after the end of the Cold War.
The 2003 Defence White Paper, titled Delivering Security in a Changing World, set out the future structure of the British military, and was preceded by the 1998 Strategic Defence Review (SDR) and the 2002 SDR New Chapter, which responded to the immediate challenges to security in the aftermath of the September 11 attacks in 2001. Published under the then Secretary of State for Defence, Geoff Hoon, the report effectively introduced a series of cutbacks to core equipment and manpower and the scaling back of a series of future capital procurement projects. This was justified due to the implementation of a policy termed Network Enabled Capability. The review also outlined a major restructuring and consolidation of British Army Infantry regiments.

It was introduced to guard key points and installations likely to be the target of enemy special forces and saboteurs, so releasing other units for mobile defence roles. It was stood down in 1992 due to budget cuts.
