[1] The Yeomanry was not intended to serve overseas, but due to the string of defeats during Black Week in December 1899, the British government realized they were going to need more troops than just the regular army.

A Royal Warrant was issued on 24 December 1899 to allow volunteer forces to serve in the Second Boer War.

In 1908 it was transferred into the Territorial Force, returning to a cavalry role and equipping as lancers, under the new title of the Lanarkshire Yeomanry.

They landed at Gallipoli in September 1915, serving as dismounted infantry, and were attached to 52nd (Lowland) Division in October; they were withdrawn in January 1916 and moved to Egypt.

[8] Whilst on the Western Front, Sergeant Thomas Caldwell of the regiment was awarded a Victoria Cross.

[18] Future Prime Minister Alec Douglas-Home, then Lord Dunglass, served in the regiment from commission as a Lieutenant in 1924,[19] rising to Major in 1933.

[20] The regiment apparently did not mechanise before the outbreak of the Second World War; after mobilisation, it was converted to the artillery role.

[4] The lineage of the regiment was revived with the formation of B (Lanarkshire and Queen's Own Royal Glasgow Yeomanry) Squadron, the Scottish Yeomanry at East Kilbride in November 1992 but that regiment was disbanded a result of the Strategic Defence Review in July 1999.

[23] The Lanarkshire Yeomanry was awarded the following battle honours (honours in bold are emblazoned on the regimental colours):[4] Honorary Distinction: Badge of the Royal Regiment of Artillery with year-dates "1941–45" and four scrolls: "North-West Europe", "Sicily", "Italy" and "Malaya".
