Special Operations Unggoy
Unggoy of this rank are part of the Special Operations division of the Covenant. Normally, Unggoy are poorly trained for combat and are usually deployed in massive numbers as cannon fodder. However, if they are given proper training they can acquire specialized roles and provide excellent support to Spec Ops teams. Often standard infantry Unggoy find themselves promoted to this rank when their commanding Sangheili is folded into the Special Operations division. Generally tougher, smarter, and certainly more aggressive than their lesser brethren, Spec Ops Unggoy are always deployed with Spec Ops Sangheili team leaders and specialized equipment and sometimes will be lead by Unggoy Ultras. These resilient, loyal, and dangerous operatives are not to be underestimated under any circumstances. If a Spec Ops Grunt's leading Sangheili is killed, rather than panicking and fleeing, they will often seek revenge, finding cover and sending plasma grenades and plasma bolts accurately at the opponent who killed the Sangheili. They are also much more accurate than their counterparts, and their armor is much more resilient to damage than other Unggoy Ranks. A number of these black-armored Grunts assaulted the Heretic Gas Mine. They were successful at aiding Arbiter Thel 'Vadamee in taking down the Heretic Leader, Sesa 'Refumee.
Special Operations Unggoy are denoted by their signature jet-black armor, which matches the black armor of their Sangheili commanders. In Halo 2, they are occasionally equipped with Active Camouflage. They are only hard to kill when they are carrying a Needler, since the Needler does not generate a glow unlike Covenant plasma weapons.
They are only called in during special combat situations, and hold a unique amount of respect for a member of their race. They are highly trained and only commanded by the skilled Special Operations Elites. Unlike most Unggoy, they are vehicle drivers. They have slightly more health than Grunt Heavies but about the same as Ultras.
SpecOps Grunts almost never panic during combat, as the Minor and Unggoy Majors almost always do when their leader is killed. They often wield Needlers, Fuel Rod Guns, Plasma Grenades, Plasma Launcher and occasionally Plasma Pistols. The biggest concern of facing a Spec Ops Unggoy, however, is that a Spec Ops Sangheili is more than likely nearby. Spec Ops Unggoy are not to be underestimated, though. Sometimes if the highest ranking Sangheili is down, the Spec Ops Unggoy will run, but to better cover and will usually send out deadly and accurate barrages of plasma grenades. This can be fatal on the higher difficulties. Like earlier, they are not to be trifled with and must be taken down with precision and speed to allow the player to survive the Legendary difficulty.
Being quite skilled fighters in comparison to the Minor and Major Unggoy and therefore not having to rely on large numbers, they usually move in teams of two or three, with one Spec Ops Unggoy wielding a Fuel Rod Gun while the others cover him with Plasma Pistols and Needlers. In Halo: Combat Evolved, it is best to target the one holding a Fuel Rod Gun as his teammates may be killed when it explodes, and also since the Unggoy fires the fuel rod gun very rapidly which can prove fatal even on Easy difficulty. In Halo 2, throwing grenades at them can be effective, especially when sticking them with plasma grenades.
- Special Operations Unggoy in Halo: Combat Evolved are similar to their Heretic "brothers". They are not deployed as cannon fodder, use either needlers or fuel rod guns, only cower in the presence of the Flood, and work alongside similar-ranking Sangheili.
- Every Spec Ops Unggoy in Halo: Combat Evolved has either a needler or a fuel rod gun, as per their status as elite infantry. The only exception to this is an Easter egg, the "Thirsty Grunt", who has a plasma pistol.
- In the Halo 2 level The Oracle's opening cinematic, the Unggoy that file in after the Sangheili have no weapons, but they have plasma pistols when gameplay starts.
- Urk has nicknamed the Spec Ops Unggoy of Halo: Reach "Starscreams" because of the spires on their shoulders.
