Jiralhanae Stalker

The Stalker is a Brute (Jiralhanae) rank.

Description
Stalkers are notable by their grey colored armor that possess integrated circuitry for Cloaking in their Power Armour as well as their cyclops-like helmet with a bright red light emitting from their "eye". They often use Radar Jammers to confuse their enemies and are the main users of Incendiary Grenades, and their main weapon seems to be the Plasma Rifle.

It is unknown how Brutes are promoted to this rank (possibly the number of casualties they inflict), but they are commonly seen acting as spies and bodyguards for Brute Chieftains. The Stalkers replaced the Stealth Elites of Halo: Combat Evolved and Halo 2 after the Elites became Separatists from the Covenant.

Appearance
The Brute Stalker does not appear in Halo 2 but is featured in two Halo 3 levels, The Ark, and The Covenant. They use their Active Camouflage to protect their Chieftains. The armor is a misty blue and covers the legs. A large helmet hides their eyes and a red/orange light, possibly a laser sight, sits on the helmet front, but you can still see some of the matted fur.

Combat
Stalkers often employ Plasma Rifles, Spikers and Incendiary Grenades in battle. One Stalker Brute was seen using a Brute Shot on the Ark. Once you spot the distinctive visual disruption, caused by their active camouflage, use your weapon and melee them. They will be stunned and temporarily visible. Follow up with more melees until they're dead. Charge a Plasma Pistol and fire at the movement shimmers and it will usually strip their power armor, making them visible.

If the Brute goes berserk, dodge the physical attacks and finish off with a melee. On higher difficulties, it is advised to use grenades, as they will blow their cover, and they can be quickly finished off by an automatic weapon. Watch for enemy fire and destroy any Radar Jammers you see deployed on the ground. Using the Power Drain will also strip their armor off, resulting in them being visible and having almost no shields. Another way to spot a Stalker is if the Stalker is standing on a glass floor, look at the glass, their feet will be visible. It is also effective to use a Spiker as the spikes are visible when stuck in the Brute. Defeating them is the easiest way to get incendiary grenades.

In the official Halo 3 guide it states that there is a 'Brute Tracker'. No such Brute has been found though it may be that they were cut from the game, or are higher ranking Stalkers.
