Somewhat akin to the Squadrons of the Terran Confederacy, the DMC appears to function somewhat independently from the space-based Dominion Armada, its officers having control over their own ships. Its logo is referred to as the "Golden Eagle", and the bald eagle has also been used in DMC heraldry.
After the Brood War, the corps carried out tasks ranging from delivering supplies to patrolling colonies for potential enemies. A DMC force was responsible for the depopulation of Candore Colony, which had been harboring a group of insurgents. It also engaged the protoss and zerg on Artika.
Elements of the Dominion Marine Corps are also present at Mar Sara, acting as security for the Kel-Morian Combine mining camps as well as fighting the zerg who invaded the planet at the same time.
By 2503, the Corps had once again become a viable force, performing services throughout the Dominion. This included countering the insurgency of Project Shadowblade.
"Each and every one of these young men and women volunteered. And after months of sacrifice and toil in training, they have earned their place among the noble Dominion Marines. They have joined humanity's vanguard. They have chosen to stand against an unforgiving universe."
