Colonial Marines / USCM

The United States Colonial Marine Corps (USCM), commonly known as the Colonial Marines, is the successor to the United States Marine Corps and is the United Americas’ primary “force-in-readiness”, who are at all times ready for immediate deployment without any additional reinforcement, training or provisioning. They specialize in force projection, being able to operate independently in environments far from home for extended periods thanks to their technological prowess and sizeable space fleet at their disposal.

The Colonial Marines, along with the United States Army, are part of the United Americas Allied Command. The primary duties of the Colonial Marine Corps are to maintain security for all United Americas signatories and at all extraterrestrial colonies that fall under United States of America’s control, and serve as the vanguard of any major combat operation. They have fought on more than two dozen worlds, including Tientsin (8 Eta Bootis A III), Helene 215, Linna 349, BG-386, LV-1201, LV-742, and the infamous Acheron (LV-426).

The National Security Act of 2101 had established the Colonial Marines and its structure. At its peak in 2165 during the Tientsin campaign, the USCM numbered over 240,000 Marines; by 2179 that number had dropped to 165,000, with a further 50,000 in reserve.
