Following the experience of the First World War, it was decided that only the fourteen most senior yeomanry regiments would be retained as horsed cavalry,[1] with the rest being transferred to other roles.

[7][5][9] By 1939 it became clear that a new European war was likely to break out, and the doubling of the Territorial Army was authorised, with each unit forming a duplicate.

The experience of the BEF in 1940 showed the problem with this organisation: field regiments were intended to support an infantry brigade of three battalions.

[9] The regiment arrived in Iraq on 20 October 1941 and was initially under command of Tenth Army before being assigned to 10th Indian Infantry Division on 19 November.

[9] In October 1943 it rejoined the 10th Indian Division,[a] serving in North Africa, Palestine and Italy, where it ended the war on the Adriatic coast near Trieste.

[24] Equipped with Sexton self-propelled 25-pounder guns, the regiment gave support to the British and Canadian forces attacking Caen (First and Second Battle of the Odon).

[25] During Operation Martlet its Sextons supported 147th Brigade and C Squadron of the Sherwood Rangers Yeomanry in their attack on St Nicholas Farm.

[27] Later they were also in action around Le Havre (Operation Astonia) as part of the First Canadian Army, at the Turnhout Canal[14] and in the Battle of the Scheldt.

These were flat, gilt, and engraved with the white horse of Kent over a scroll inscribed 'INVICTA' over the letters KY. Brass KY shoulder titles were worn on battledress by all ranks, and while in the Middle East officers wore a khaki drill slip-on shoulder strap below the rank badges with KY embroidered in white.

The buttons, shoulder titles and arm badge continued to be worn after the war by 297 LAA Rgt until conversion to RAC in 1961.
