Template:Ratings Template:Mombasa Locations Grid Kilo 23 was a sector of the United Nations Space Command city Old Mombasa on the planet Earth.
It consisted of a broad highway, and during the Battle of New Mombasa, a Covenant Scarab was defending this grid sector, along with great numbers of other Covenant forces. A UNSC strike force of four Warthogs and three Pelican Dropships were dispatched over Grid Kilo 23 to attack the Covenant ship that was commanding the Covenant forces in the First Battle of Earth (where the Battle of New Mombasa had originated from).
Marine reconnaissance observing the grid sector noted the high Covenant troop concentrations, but failed to see the Scarab battle walker. As the three Pelicans neared the Scarab, unaware of its presence, the Scarab shot two of them down with its plasma weapons. There were several survivors at each crash site, though in both cases the pilots perished in the crash. One of them consisted of SPARTAN-117, Sergeant Avery J. Johnson, and three anonymous Marines - two with Battle Rifles and one with an SMG. The second was carrying a squad of ODSTs and crashed landed in a beach behind Hotel Zanzibar. The last one was vaporized by the Scarab. It is also interesting to note that Kilo 23 is the ID of a Pelican dropship stationed aboard the UNSC Forward Unto Dawn at the time of the Second Battle of Earth. A possible explanation for this is the fact that the maximum respawn time that can be shown in Halo 2 multiplayer is 1023 seconds, or 210 -1.
