93rd Searchlight Regiment, Royal Artillery was an all-female British air defence unit during World War II, formed in October 1942 and disbanded in July 1945.

[1] Searchlights were of great importance in the Second World War as they were needed to illuminate the German Bombers flying over Britain, so that the men operating the anti-aircraft guns could shoot them down before they had a chance to drop any bombs on the British towns and cities.

The experiment proved successful and General Pile later wrote that: "They showed themselves more effective, more horror inspiring and more blood-thirsty with their pick-helves than many a male sentry with his gun, as several luckless gentlemen found to their cost".

On 2 December 1941, the Under Secretary of State in the War Office wrote a letter recommending that members of the ATS be deployed in searchlight duties.

[11][12] Members of the ATS on the posted strength of Royal Artillery units wore the RA's 'grenade' collar badge above the left breast pocket of their uniform jacket.
