Many of the UNSC’s advancements can trace their roots to technology recovered from the Covenant or the Forerunners. The Mjolnir variant known as Stalker, can count itself among the former.
While all of the Jiralhanae are terrifying on the battlefield, the Brute warriors known as Stalkers were among the most dreaded. Capable of cloaking themselves, hunting their quarry, and waiting for the just the right moment to strike; they were fearsome opponents.
The Naphtali Contractor Corporation [NCC] recognized the potential of the Brute Stalker technology recovered after the war ended, and set to work on an armor design the would aid Spartans in tracking important targets. Even off world if necessary.
Thanks to the intel from the Brute Stalker kits, the Stalker variant possesses an impressive array of hunter-tracker which are considered top of the line. A hold over from the original Jiralhanae design is the almost box like shape of the helmet, and the bulky chest plate. NCC however, saw fit to modify the pauldrons, making them large enough to better cover the shoulder and upper arm. These armor designs make the Stalker armor excellent at engaging enemies in close quarters combat and is intentional on the part of the designers. The Stalker armor is primarily engineered to stalk targets at such a close range, that many traditional hunter-trackers would be unnerved.
The Stalker variant was famously used by Delta Six Division operatives alongside the Ranger and Wetwork variants to great effect during the raids on Talitsa. The Spartans trackers that donned this armor were invaluable in both locating rebel leaders and eliminating them.
The STALKER specialization is available for requisition upon reaching a Spartan Rating of 50. Upon completing the STALKER training, Spartans are issued a modification to enhance their armor should they choose to equip it.
NEMESIS MOD: A specialized variant of a classified tracking system suite used only in training, the Nemesis mod allowed Spartans to track the last enemy that “killed” them.
