Ann-Britt McMillan (b. ???? - d. ????) was a Colonel within the Magistracy Armed Forces during the Reunification War-era invasion of the Magistracy of Canopus by the Star League, and was responsible for leading the defending units on Eleusis during the six-month campaign to conquer the world by the SLDF VII Corps between April and September 2579.
Historical: Reunification War doesn't list which unit McMillan commanded directly, but the defending forces on Eleusis consisted of a number of armor and infantry regiments plus three regiments from the Chasseurs á Cheval brigade, the 1st, 2nd and 3rd Canopian Light Horse regiments, and the mercenary unit Samuelson's Slaughterers. Given the precendence of the Chasseurs á Cheval within the MAF it is therefore likely, but not certain, that McMillan was the commander of one of the three Light Horse regiments.
