SPARTANs are the most skilled and disciplined soldiers available to the UNSC. Conscripts to the later two programs take part in intense combat training at an early age, and are given the performance enhancing MJOLNIR Powered Assault Armor and the Semi-Powered Infiltration Armor, generally to the SPARTAN-IIs and the SPARTAN-IIIs, respectively, (with the Special Warfare Command fireteam Noble Team being a known exception), making them extremely skilled in combat.
Below are all known SPARTAN squads and companies.
- SPARTAN Program
- SPARTAN-III Program
- SPARTAN-IV Program
Many UNSCDF personnel were part of the ORION Project, specializing in covert operations, assassinations, and conducting high-priority, high-risk operations against enemy forces. Numerous units are under the supervision of Section Three within the Office of Naval Intelligence, which coordinates their special operations missions; one such unit would be the members of the various SPARTAN-II teams.
Orbital Drop Shock TroopersEdit
The Marines Corps' Orbital Drop Shock Troopers are an important part of any UNSC invasion force. Disciplined and skilled, they drop into the most hostile areas via SOEIVs. They attempt to complete some of the most difficult tasks in hostile areas, such as clearing enemy ground forces or establishing landing zones for incoming Pelicans.
Below are all known ODST units.
- 105th Marine Expeditionary Unit (SOC)
- 105th Drop Jet Platoon
- 340th ODST Combat Training Unit
- Echo Team
- Kilo Team
Special Warfare Command / SPECWARCOMEdit
Special Warfare Command (SPECWARCOM) is a special forces branch of the United Nations Space Command, directly subordinate to Unified Ground Command and indirectly to UNSC High Command. SPECWARCOM is the special forces branch for ground forces, which is mainly the UNSC Army. The command consists of various special operations teams that conduct covert operations against both the insurrectionists on UNSC controlled planets and the Covenant. The command also has tactical control of SPARTAN units for specific operations that fall under Unified Ground Command jurisdiction and this was evident during the Fall of Reach.
