Alan Mace

Colonel Mace governed the British division of UNIT in 2009.

Upon first meeting the Doctor, he was awe-struck and saluted him, but as the operation went on he became more irritated by the Doctor's cavalier approach and dismissal of the military's tactics. When the Sontarans revealed themselves, he clashed with the Doctor when UNIT tried to launch a nuclear strike on the Sontaran warship, and was later forced by the Doctor to call a full retreat from the ATMOS factory when the Sontarans began slaughtering the soldiers present.

Mace coordinated the UNIT counter offensive to regain the ATMOS factory, having the soldiers rearm themselves with rad-steel coated bullets (preventing the Sontaran's field that negated copper bullets) and calling in the Valiant to clear the gas around the area. When beginning this operation, he finally snapped at the Doctor over his "lack of faith".

He personally killed Sontaran Commander Skorr with a pistol; rather than shoot the Sontaran from behind, he demanded that he face him before shooting him, showing that he was an honourable combatant. After the defeat of the Sontaran plan, he shared a kiss with one of his captains, Marion Price. (TV: The Sontaran Stratagem / The Poison Sky)

By the time of the 456 incident in September 2009, Colonel Mace was stationed in Vancouver. (TV: Children of Earth: Day One) He was still in Vancouver in June 2011. (PROSE: The Forgotten Army)
