The Royal Scots Greys were re-equipped as an all-Sherman regiment, with Sherman II tanks. The regiment continued to refit through the short Sicilian campaign, not seeing action until it was part of the Salerno landings (Operation Avalanche), part of the Italian Campaign, in September 1943. The regiment was assigned to 23rd Armoured Brigade, alongside 40th and 46th RTR. The 23rd was an independent brigade reporting directly to British X Corps, which was itself under command of the U.S. Fifth Army.
