Following the North African campaign, it re-equipped with M10 tank destroyers. It landed at Salerno with Operation Avalanche in September 1943, attached to the 36th Infantry Division; at the end of the month it was assigned to the 3rd Infantry Division, with whom it would serve for the remainder of the war. With the 3rd, it landed at Anzio in Operation Shingle in January 1944, crossing the beaches virtually unopposed and taking up positions on the right of the beachhead. It saw action during the push to expand the beachhead and then the bitter defence against a German counterattack; on 29 February, it was employed as part of an active defence by the 3rd Division, repulsing attacks by three separate divisions. It entered Rome in June 1944.
