SPARTANs are statistically the most effective infantry assets available to the UNSC, personally responsible for countless victories against both the Covenant Empire, its remnants, and insurrectionist forces. Conscripts of both the S-II and S-III programs take part in intense combat indoctrination from an early age and recieve extensive biological augmentation procedures. The S-II, S-IV, and some S-III personnel were equipped with advanced MJOLNIR powered assault armor to further increase their physical superiority. The SPARTANs exceptional lethality in combat lead some to believe they were actually invincible. Notably, they were feared among the Covenant as demons.
Below are all known SPARTAN squads and companies.
