When Dr. Halsey discovered and hacked Colonel James Ackerson's computer at CASTLE Base, she found a folder called S-III. Contained in the S-III folder was the following:

CPOMZ

The CPOMZ file contained star charts. Halsey used the CPOMZ starchart to locate the Spartan-IIIs on Onyx. The letters CPOMZ are also an acronym for: Chief Petty Officer Mendez (CPOMZ) the man who trained the Spartans at a young age. This lead Halsey to believe that Chief Petty Officer Mendez was somehow mixed up with Ackerson.

KING UNDER THE MOUNTAIN

KING UNDER THE MOUNTAIN file contained:

• Information on the Forerunner artifact found on Sigma Octanus IV.
• A full map of the CASTLE base facility on Reach that included a path to artifact, the Forerunner Crystal, beneath the surface of Reach.
• Along with the map was a complete survey of Mechanite Mountain, where the original mineral mines were located before they were taken over by ONI. Mechanite Mountain was an extinct volcano which is where Dr. Halsey found the Forerunner Crystal artifact.

Spartan-IIs

In the folder she found extensive records of the Spartan II program and its members. This indicated that Ackerson had knowledge of and an interest in the supposed top secret Spartan II program.
