Grid Kilo 23

"Immediate: Grid kilo two-three is hot. Recommend mission abort."

- A Marine recon unit during the Covenant attack.

Grid Kilo 23 was a sector of the city of Old Mombasa on the planet Earth.

It consisted of a broad highway, and during the Battle of 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 Prophet of Regret's assault carrier, Solemn Penance, that was commanding the Covenant forces.

Marine reconnaissance observing the grid sector noted the high Covenant troop concentrations, but failed to see a nearby Scarab battle walker, which was behind a building. 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 John-117, Sergeant Avery J. Johnson, and three anonymous Marines, two with Battle Rifles and one with an SMG. The second was carrying Gunnery Sergeant Stacker and a squad of ODSTs which crashed landed in a beach behind Hotel Zanzibar. The last one escaped the Scarab without being hit, it later picked up Johnson.

Trivia
In Halo 3, there is a Pelican dropship with the designation of Kilo 023.
