UNSC Engineering Corps

From Halopedia, the Halo wiki

UNSC Engineering Corps or ENGCORP for short, is a branch of UNSC HIGHCOM devoted to surveying viable planets for colonization or terraforming. Engineers from ENGCORP visit these planets, and make field reports doccumenting features of the planet, suitability for colonization, and other details that would be necessary for a possible colonization. These reports are then published.
