S-III

This article is about the folder called S-III. Were you looking for SPARTAN-III program or ONI's Section III?

S-III was a folder on Colonel James Ackerson's computer at CASTLE Base on Reach. When Dr. Halsey hacked the computer, she discovered two folders, S-III and KING UNDER THE MOUNTAIN.

CPOMZ

Contained in the S-III folder was a file called "CPOMZ", which contained celestial coordinates in the form of a 512-character alphanumerical string. Halsey used the CPOMZ coordinate string to locate the planet Onyx which housed the SPARTAN-III program. The letters CPOMZ are also an acronym for Senior Chief Petty Officer Mendez, the man who trained the SPARTAN-IIs at a young age. This lead Halsey to believe that SCPO Mendez was somehow mixed up with Ackerson.

Spartan-IIs

In the folder were also extensive records of the SPARTAN-II program and its members, including a great deal of Spartan biomedical data.<ref name= "GOOC16"> This indicated that Ackerson had knowledge of and an interest in the supposed top secret SPARTAN-II program.
