The 101st Heavy Anti-Aircraft Regiment, Royal Artillery was an air defence unit of Britain's Territorial Army raised in northern Scotland just before World War II. After defending the naval base of Scapa Flow against air attack in the early part of the war, the regiment went to India and later took part in the Burma Campaign in the anti-aircraft role and with heavy howitzers in support of ground forces, even on occasion fighting as infantry. It was reformed in the post-war TA and continued until the abolition of Anti-Aircraft Command in 1955.

The Inverness-shire Royal Horse Artillery was a Territorial Force Royal Horse Artillery battery that was formed in Inverness-shire in 1908. It saw active service during the First World War in the Sinai and Palestine Campaign with the ANZAC Mounted Division from 1916 to 1918. A second line battery, 2/1st Inverness-shire RHA, served in the United Kingdom throughout the war. It was disembodied after the end of the war and was reconstituted as a Royal Field Artillery battery in 1920.
