Overview[edit]

Design details[edit]

The SECOPS helmet is a fully-enclosed helmet equipped with an off-world rebreather system,[3] with the TorLINK-TS target acquisition system being an additional optional attachment.[4] Typically complemented by a stunblade,[2] the armor is made with a specialized composite engineered by the Office of Naval Intelligence, while the pauldrons are reinforced for heavy combat,[3] with attach points for lights, acoustic hailers, and other security gear.[5] The gear is typically worn above a more standard ballistic assault vest.

Usage[edit]

The SECOPS armor was designed for counterinsurgency and precision interventions.[6][Note 1] The SECOPS armor is typically used by ONI Response Teams and Security Force officers,[1][3] especially in high-threat environments.[2] It is also worn by heavy infantry in the UNSC Marine Corps.[7] The armor is also upgraded to be compatible with the MJOLNIR [GEN3] platform.[1]

During the Battle of Requiem in July 2557, Marine commissioned officer Paolo Jiminez used a set of green SECOPS armor.[8]

SECOPS armor was dispatched to the Avery J. Johnson Academy of Military Science by ONI Security.[6][Note 1]

In-game information[edit]
