UNSC Department of Commercial Shipping

The UNSC Department of Commercial Shipping, abbreviated "DCS" is a organization in the United Nations Space Command responsible for maintaining the UNSC commercial fleet and regulating interstellar commerce and shipping between colony worlds.^[1] Each of their cargo ships is designated with a freighter identification code. Some of their ships were attacked by the Covenant ship Minor Transgression in 2524, which led to beginning of the Human-Covenant War.

Lieutenant Commander Jilan al-Cygni posed as a DCS employee as cover for her assignment from the Office of Naval Intelligence to investigate the disappearance of freighters from Harvest.^[2]
