Between the wars, it was converted to an Armoured Car Company before being expanded back to regimental size and forming a duplicate regiment, the 4th County of London Yeomanry (Sharpshooters). Both regiments served throughout the North African Campaign (notably at El Alamein), before moving on to Sicily (3rd CLY) and Italy. Both regiments returned to the United Kingdom in time to prepare for the opening of the Second Front.
