36th Anti-Aircraft Brigade was an air defence formation of Britain's Territorial Army, created in the period of tension before the outbreak of World War II. It was responsible for defending eastern Scotland.
Origins
Large numbers of Territorial Army units were converted to anti-aircraft and searchlight roles in the Royal Artillery and Royal Engineers during the 1930s, and higher formations were required to control them. 36th Anti-Aircraft Brigade was formed on 1 May 1938 at Edinburgh, to command the units responsible for the air defence of the City of Edinburgh and the Firth of Forth. Its first commander was Brigadier G.C. Kemp. Initially the brigade was formed within Scottish Command, later being subordinated to 3rd Anti-Aircraft Division when that formation was raised at Edinburgh on 1 September 1938 to command all the AA defences of Scotland and Northern Ireland. Subsequently, Anti-Aircraft Command was created on 1 April 1939 and took control of AA Defence throughout the United Kingdom.
Mobilisation
The TA's AA units were mobilised on 23 September 1938 during the Munich Crisis, units manning their emergency positions within 24 hours, even though many did not yet have their full complement of men or equipment. The emergency lasted three weeks, and they were stood down on 13 October. In February 1939 the existing AA defences came under the control of a new Anti-Aircraft Command. In June a partial mobilisation of TA units was begun in a process known as 'couverture', whereby each AA unit did a month's tour of duty in rotation to man selected AA and searchlight positions. On 24 August, ahead of the declaration of war, AA Command was fully mobilised at its war stations.
The Blitz ended in May 1941, but there were occasional raids thereafter and AA Command continued to strengthen its defences. Newly formed units joining AA Command were increasingly 'mixed' ones into which women of the Auxiliary Territorial Service were integrated, while those armed with Z Battery rocket projectiles were partly manned by members of the Home Guard. At the same time, experienced units were posted away for service overseas. This led to a continual turnover of units, which accelerated in 1942 with the preparations for Operation Torch.

Later war
In August 1942, 3rd AA Division HQ moved south to help AA Command control the reinforcements to countering the Luftwaffe 'hit-and-run' raids against the South Coast, and the brigade briefly came under the command of 7th AA Division. However, in October 1942 AA Command reorganised its structure, replacing the AA Divisions with AA Groups coinciding with RAF Fighter Command's Groups. 36 AA Bde came under 6 AA Group covering Scotland.

Disbandment
By early 1944, AA Command was being forced to release manpower to 21st Army Group for the planned Allied invasion of continental Europe, and a number of AA batteries, regiments and formations had to be disbanded. 36th AA Brigade was one of those to be disbanded, on 20 February 1944. 6 AA Group HQ went south to take over part of the responsibility for defending the Overlord embarkation ports, and a new 8 AA Group was formed to cover Scotland. 122nd HAA Regiment went to Southern England with 6 AA Group and joined 30 AA Bde while the rest of 36 AA Bde's units joined the new 8 AA Group.
Postwar
When the TA was reformed in 1947, 36 AA Bde's Regular Army units reformed 12 AA Bde, while the TA portion was renumbered as 62 AA Bde, both at South Queensferry and forming part of the Edinburgh-based 3 AA Group. 62 AA Brigade had the following composition:
494 HAA Rgt – see above
514 LAA Rgt
519 LAA Rgt
532 LAA Rgt – see above
587 LAA Rgt
However, the reformed brigade was short-lived, being disbanded in September 1948.
