148th Regiment RAC was formed in November 1941 by the conversion to the armoured role of the 9th Battalion, Loyal Regiment (North Lancashire), a war service battalion hat had been raised in 1940 as part of the rapid wartime expansion of the British Army.

[2][3] Training was hampered by the shortage of rifles and equipment, and the tented camp became uninhabitable during winter gales, with the battalions having to go into billets.

[9] 33rd Armoured Brigade had been delayed in arrival, and its absence was sorely felt by the British Second Army during the tough fighting around Villers-Bocage (13–16 June).

[10] Once in Normandy, the brigade moved between various Divisional, Corps and Army commands as required, but usually it operated with 51st (Highland) Infantry Division.

During Totalize, 'B' Sqn attacked the village of Tilly la Campagne, which was 'browned' with the tanks' Browning machine guns.

On 13 August, the regiment was shelled while relieving 144 RAC, and the commander of 'B' Squadron and several other ranks were wounded.

[15] The following day, 148 RAC took part in Operation Kummel, once more in support of 51st (Highland) Division, and lost another squadron commander;[15] this was to be the regiment's last action.

On 15 August, the regiment was ordered to disband, due to a severe shortage of manpower in the British Army at the time.
