UNSC Special Forces

The Special Forces comprise the special operations units of the United Nations Space Command.

Naval Special Warfare Command
Naval Special Warfare Command (NAVSPECWAR) is a major special forces division under the oversight of UNSC Naval Command. The branch includes the Orbital Drop Shock Troopers and operatives of the now defunct ORION Project. The SPARTAN-IIs and SPARTAN-IIIs also served under NAVSPECWAR until early 2553, when they were folded into the independent Spartan branch. NAVSPECWAR specializes in covert operations, assassinations, and conducting high-priority, high-risk operations against enemy forces. Some NAVSPECWAR units fall under the operational supervision of Section Three within the Office of Naval Intelligence.

NAVSPECWAR also includes Naval Special Weapons (NAVSPECWEAP), which controls the deployment of unconventional weapons such as nuclear warheads in NAVSPECWAR's operations.

SPARTAN
Spartans are the most skilled and disciplined soldiers in service to the UNSC. SPARTAN-II and SPARTAN-III personnel took part in intense training from childhood; most saw combat by their early teens. The SPARTAN-IIs wear performance-enhancing MJOLNIR Powered Assault Armor, whereas most SPARTAN-IIIs wore Semi-Powered Infiltration armor. After the Spartan branch's establishment, NAVSPECWAR only has operational command over Blue Team.

Orbital Drop Shock Troopers


The Marines Corps' Orbital Drop Shock Troopers (ODST) are an important part of the UNSC's offensive operations. Disciplined and skilled, they drop into the most hostile areas via SOEIV drop pods. 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 dropships.

Unified Special Warfare Command
Unified Special Warfare Command (USW) often simplified as Special Warfare Command (SPECWARCOM), is a special forces branch under the authority of Unified Ground Command. It maintains oversight of special operations carried out by the UNSC Army. Given UNICOM's authority over the UNSC Marine Corps on the whole, it is possible that USW also oversees Marine special force units apart from the ODST, who fall under NAVSPECWAR's authority.

Known units
