Biography
Before Operation FIRESIDE commenced during the Battle of Ariel, Oslo Brimley had a heated debate with Kojo "Romeo" Agu after the latter doubted the fighting capability of a SPARTAN. Brimley brought the death of his old friend, the ODST Enrico Langston, at the hands of a teenage SPARTAN-II, which had secretly been orchestrated by Office of Naval Intelligence.

After Romeo suggested Langston was weak, Brimley punched his face, breaking his nose, but was later stopped by Taylor "Dutch" Miles.
