By the end of 1944, serious naval attacks on the United Kingdom could be discounted and the War Office began reorganising surplus coastal units into infantry battalions for duties in the rear areas. Meanwhile 21st Army Group fighting in North West Europe was suffering a severe manpower shortage, particularly among the infantry. In January 1945, the War Office accelerated the conversion of surplus artillery into infantry units, primarily for line of communication and occupation duties, thereby releasing trained infantry for frontline service. On 15 January 1945, RHQ 532nd Coast Rgt and HQ Milford Haven FC reorganised to the infantry role as 620th (Pembroke) Infantry Regiment, RA, with A to E Btys, though it does not appear to have served overseas.
