"Let's cut the bullcrap, Sergeant. I outrank you."

- Smith to Lopez after the Marines discovered his identity.

Major John Smith was an Office of Naval Intelligence scientist working aboard the ONI-commissioned prison vessel Mona Lisa in October 2552. While aboard he studied several Flood-infected Sangheili in the hope turning the Flood into warriors for the UNSC. Whether ONI approved of this is unknown. When the ship was overridden by the Flood, he remained hidden inside a small panic room until he was discovered by Sergeant Zhao Heng Lopez's squad. He later escaped aboard their Pelican, betraying the squad.

He was likely court martialed after his escape, as Captain Tobias Foucault of the prowler planned to have him.
