Jameson Locke

Lieutenant Commander Jameson Locke is an ONI Acquisitions Specialist.

Biography
Locke was born on March 15, 2529, on Jericho VII. When he was six years old, Jericho VII fell to the Covenant Empire and Locke was evacuated. His parents were killed during the assault.

On September 26, 2552, Locke compiled a target profile report regarding Thel 'Vadam's personal history during the war, including the glassing of Reach, the destruction of Installation 04, and the Great Schism. He was tasked to find John-117 and met with Thel 'Vadam to better learn about John's history via battle recordings and testimonies from the Arbiter himself.

Sedra crisis
After the war, Locke was part of a unit sent by the UNSC to investigate Covenant activity on Sedra. . During the middle of a covert operation, Locke and a team of ONI agents attempted to prevent a rogue Sangheili from detonating an unidentified weapon. Locke's efforts failed, which results in the deployment of a biological weapon that only affects humans. Locke's investigation into the source of the biological weapon leads ONI to a fragment of Installation 04. Working with Colonel Randall Aiken and a small team of Sedra militia members, the ONI team lands on the fragment. Although the joint strike team captured two human smugglers, they are ambushed and stranded by Lekgolo worms during extraction.

With their Condor dropship disabled, the surviving humans attempt to make their way to the smugglers' tug ship, and have a problem. The tug itself can only carry two passengers, which ultimately splits the group into two, Locke with Randall and Sedra militia member Mercer, while two members of Locke's team are with a surviving smuggler. Locke's group finds the crashed Condor, barely flight-capable. Randall volunteers himself to detonate the nuclear ordinance while Locke and Macer use the Condor to reach the tug. Locke and Macer successfully escape the Halo fragment with the commandeered tug before its detonation.

Searching for John-117
Some time after the Sedra crisis, Locke undergoes SPARTAN augmentations, and leads an ONI SPARTAN team to search for John-117. As a first step, Locke makes contact with Thel Vadam in order to gain insight on their past history while carrying out a UNSC-Sanghelli joint operation.

Personality
Locke is a competent soldier who approaches combat situations with caution and logic and inspires loyalty in those under his command. However, he is troubled by some aspects of the organization he serves under.
