Centurion Team is a Special Warfare team consisting of four SPARTAN-IIIs. They, along with the one hundred and ninety three other candidates not chosen for the official company, were augmented separately from the others, and issued new suits of MJOLNIR Powered Assault Armor/Mark IV[B]. While this separated them from their friends, it also spared them from the destruction of the company during Operation: PROMETHEUS. They would proceed to go on missions across many different colony worlds, fight not as suicide soldiers, but as Spartans.
