UNSC Department of Commercial Shipping

The UNSC Department of Commercial Shipping, abbreviated DCS, is an organization in the United Nations Space Command responsible for maintaining the UNSC commercial fleet and regulating interstellar commerce and shipping between colony worlds.^[1] Their cargo ships are typically named in reference to terms and phrases relating to trade and logistics, and each is designated with a freighter identification code. Some of these freighters 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]
