In December, the regiment fought at various times under command of the 7th Armoured Division's Support Group and the 4th Armoured Brigade. It rejoined the 22nd Armoured Brigade in the last week of December and completed a long march across the desert as the British and Commonwealth forces pushed the Axis forces out of Cyrenaica. As Operation Crusader drew to a close, the regiment saw action around Chor es Sufan on 28 and 30 December, after which the 7th Armoured Division was relieved by the 1st Armoured Division. In total, the regiment had suffered 169 casualties.
