The 502nd Regiment is a front for the Dominion Intelligence Section disguised as a Dominion Marine Corps regiment stationed at Outpost 38-BC-16. The regiment's Quartermaster Hadar filed a complaint to Major Lance Wallace stating that the last ammunition shipment was behind schedule, and was nine weeks late. The base was down on ammunition due to a wasted training exercise by Private Jenkins. In addition, he complained that the degrading quality of the MREs being shipped to their base was causing low morale, and that the base was considering using them as reserve ammunition.
One of its divisions was the Sustainment Division, which handled all supplies and ammunition for the regiment.
