Battle of Mombasa[]

“When I asked for reinforcements, I didn't think they'd send a Spartan.”

After his unit's deployment to New Mombasa, Banks was in command of "A" Company after their original commander was hit when they dropped in.[1] As the ranking surviving officer, he was forced to take command of the marines in the area, though he was likely under the command of the Colonel in charge of the defense of the city.

After John-117 broke through Covenant defenses, Corporal Perez guided him and Cortana to Banks while briefing them. Staff Sergeant Banks was found on the roof of a building (an impromptu command center) held by the Marines of "A" Company. After seeing John-117, Sergeant Banks expressed surprise at his appearance. After a Scarab crushed most of his defenses, he called on John-117 to help him take out the Scarab. Along with his platoon he fired upon the Scarab from the cover of a nearby bridge while John dove onto the Scarab, killing its crew and disabling it.

Battle of Installation 05[]

After the Battle of Mombasa, Banks was quickly transferred to the UNSC In Amber Clad, which left Mombasa with Prophet of Regret's Solemn Penance as it jumped into slipspace.

In the Battle of Installation 05, Sgt Banks was one of the NCOs dispatched from In Amber Clad. He was later captured by Jiralhanae forces, along with Sergeant Major Johnson and Gunnery Sergeant Marcus Stacker to be used to activate the installation.

However, the three managed to break free when Thel 'Vadam and several other Sangheili attacked the Jiralhanae. The three then helped the Arbiter take back a Scarab walker. Stacker and Banks then boarded the Scarab along with Johnson.

Battle of Installation 00[]

Banks returned to Earth with the survivors from Installation 05, and participated in the Battle of Tsavo. When the Covenant Separatist Fleet of Retribution and the UNSC forces under the command of Lieutenant Commander Miranda Keyes traveled through the Portal to the Ark, Banks was among the Marines stationed aboard the UNSC ships.

When the battle broke out, he was deployed to the surface of the installation, where he fought alongside John-117. It is unknown whether or not he survived.[2]
