This suit of combat armor only referred to as the Black Body Suit is a vacuum-enabled suit of light body armor used by the United Nations Space Command in operations in sealed vacuum environments.[1]


This body-suit is a black, form-fitting suit of polymer body armor, able to deflect small-caliber rounds.

The suit is equipped with cooling and heating units that mask the infrared signature of the wearer, as well as creating a comfortable environment. The helmet has encrypted communications gear and a HUD, along with thermal sensors and motion detectors. The whole suit is fully sealed and gas tight, making them wearable in a vacuum for up to fifteen minutes when equipped with an oxygen tank.[1]

Unfortunately, the suit's general complexity leads to complications. Over prolonged periods of time the suit will become uncomfortable to wear, is difficult to repair in the field, and requires frequent repairs. The suit also limits the wearer's motion, as remarked by SPARTAN-087.[1]


These suits saw extensive use during the 2520s. They were used by the SPARTAN-IIs in several missions, before they got their trademark MJOLNIR Armor. One of these missions involved infiltrating a Rebel base in the asteroid Eridanus secundus in the Eridanus system.[1]


  • The Black Body Suit shares some similarities with ODST battle armor. Both suits have an oxygen reserve of fifteen minutes and are black. However, the ODST armor is much bulkier than the black body suit, though it likely houses a similar body suit under the armor plating.
