I like to assume for debate purposes we're dealing with the Covenant at the height of their power, which I should think would be prior to the Fall of Reach. Also we're assuming the full strength of Covenant forces not just the expeditionary force which was primarily composed of Sangheii. So that's the combined might of the Covenant Empire, Brutes and Elites as they were never assembled during the Halo series.
