Alan Mace

"Attention all troops! The Sontarans might think of us as primitive, as does every passing species with an axe to grind. They make a mockery of our weapons, our soldiers, our ideals. But no more. From this point on, it stops. From this point on, the people of Earth fight back and we show them. We show the warriors of Sontar what the human race can do."

- Colonel Mace.

Colonel Alan Mace was the man in charge of UNIT from 2005, replacing Colonel Brimmicombe-Wood. He was not present at the Tower of London base for The Christmas Invasion, for unknown reasons. In contrast, he took personal command over Operation Blue Sky.

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. (DW: The Sontaran Stratagem/ The Poison Sky)
