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.

A Scottish regiment is any regiment that at some time in its history has or had a name that referred to Scotland or some part thereof, and adopted items of Scottish dress. These regiments were created after the Acts of Union in 1707 between England and Scotland, either directly serving Britain during its various wars, or as part of the military establishments of Commonwealth countries. Their "Scottishness" is no longer necessarily due to recruitment in Scotland nor any proportion of members of Scottish ancestry.
