UNSC Engineering Corps

UNSC Engineering Corps or ENGCORP for short, is a branch of the United Nations Space Command. Their responsibilities include various tasks related to science and engineering, such as surveying viable planets for colonization or terraforming. Engineers from ENGCORP visit these planets, and make field reports documenting features of the planet, suitability for colonization, and other details that would be necessary for a possible colonization. These reports are then published for command to give the "O.K." signal. The Engineering Corps is credited for discovering Onyx, the planet that housed the training for the SPARTAN-IIIs and which eventually turned out to be an artificial world constructed by the Forerunners to house a massive shield world.

A number of UNSC Marine Corps personnel also serve under ENGCORP. Their tasks include the protection and if necessary, demolition of classified research sites. One of the Marine units serving under the Engineering Corps is the Hades Corps, which was tasked with the demolition of ONI Materials Group's Weapons Research Facility T12A on Algolis at some point during the Human-Covenant War.
