Project Epsilon was an ONI project that created "super soldiers" of a very high class. They created troops that were effective in most combat roles that could report directly to ONI and do jobs that ONI did not want the rest of the armed forces of Humanity to know about. This had many benefits. The group reported directly to ONI Section One, and to the rest, indirectly. They had their own armor suit, based on that of the ODST. They could requisition vehicles. The troops also had an AI of their own. After a harsh training, they were ready to become ultimate soldiers and gather intelligence for ONI.
