In 1961 the regiment was amalgamated with the Queen's Own Cameron Highlanders to form the Queen's Own Highlanders, which merged, in 1994, with the Gordon Highlanders to form the Highlanders.

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.
