On 13 December 1943, the War Office decided to expand the squadron into a regiment equipped with a combination of light tanks and conventional reconnaissance vehicles such as scout cars, and on 1 April 1944, it was re-designated as the 6th Airborne Armoured Reconnaissance Regiment. The regiment consisted of a Headquarters Squadron, a Light Tank Squadron and a Reconnaissance Squadron; two Tetrarchs, the Mark 1 CS variation, were attached to the Headquarters Squadron, but the Light Tank Squadron, also known as 'A' Squadron, received the majority of the Tetrarchs. 'A' Squadron had approximately nineteen Tetrarchs split between six troops, two of which were of the CS variation and the rest were armed with 2 pounders fitted with Littlejohn adaptors. On 24 May 1944, after participating in a further series of exercises and manoeuvres, 'A' Squadron moved from their training area to a transit camp at Tarrant Rushton airfield, while the rest of the regiment moved to RAF Brize Norton airfield the next day; from these two airfields, the regiment would be transported from to participate in the British airborne landings in Normandy. The operation began on the night of 5 June, with the deployment of 6th Airborne Division to eastern Normandy. It was tasked with protecting the eastern flank of the Allied seaborne landings, securing strategically important areas east of Caen, capturing several important bridges over the Caen Canal and River Dives, and destroying a coastal artillery battery. Insufficient transport aircraft were available to land all three of the division's brigades simultaneously; one would have to be landed in a second lift later in the day. Major General Richard Gale had initially intended for the 6th Airlanding Brigade, to which the 6th Airborne Armoured Reconnaissance Regiment was attached, to be landed first; however, aerial photography revealed that anti-glider poles had been erected in the landing zone selected for the brigade. Therefore, Gale decided that the 3rd Parachute Brigade and 5th Parachute Brigade (which did not utilise gliders) should land in the first lift to clear the landing zones, allowing the 6th Airlanding Brigade to land in the second lift.
