UNIT's first major appearance in the new series was in "The Christmas Invasion" in 2005. Here, a new insignia has been designed based on the "Battlefield" version. The troopers wear black uniforms consisting of police clothing/SAS Counter Revolutionary Warfare (CRW) Wing overalls and a red Royal Military Police beret, and equipment. Insignia is a small silver-metal UNIT parawings on a red beret and a large UNIT Parawing patch worn over the left breast pocket on the utility vest or fatigues. Commanding officers wear with UNIT insignia. Variations include Captain Magambo from "Turn Left" (2008) wearing a black version of service dress with a red beret, and Colonel Karim in "The Sarah Jane Adventures" story "Death of the Doctor" wearing black civilian clothes with UNIT insignia and rank epaulettes. This UNIT also includes a uniform for scientists: a lab-coat with the UNIT insignia on the chest.
