History of the UNMC

The UNMC was created following the passing of The National Security Act. Its task was primarily assigned to the defense of the growing frontiers of the United Nations government. The frontier had grown during the Great Space Race, involving the United Nations, Three Suns Empire and Socialist Progressive Peoples.

It was not until after the Sol Campaign, that the United Nations military and government made use of the UNMC as an offensive might, using it to wrest control of the frontier through force. Their Mars and Sol colony assets shaken due to SPP proxy funding, and an ignited civil unrest that led to a full sized conflict costing thousands in Sol. This led to a belief for the UN that a similar fate would befall the American colonies which were farther from the reach of the standard military. The belief quickly led to the rapid mobilization and armament of the UNMC, along with the adaption of unrestricted military doctrine on civilian colonies. The result caused the ignition of Operation Justice.

Operation Justice became the UNMC's first offensive deployment, tasked with retaking the colony of Justice whose government was overthrown in a social coup supported by the Socialist Progressive Peoples. The number of marines peaked at 240,000 active combat Marines and over a dozen combat warships, resulting in one of the largest conflicts fought between two major super-powers in decades. Eventually both sides withdrew after the usage of nuclear weaponry, devastating the population and leading to the establishment of the Stellar Accords.

Current day, the UNMC finds itself locked in a war on insurgency, with everyday seeing another colony on the frontiers go dark due to an unseen enemy, or another colony declaring itself independent and aligning itself with the loose conglomerate known as the Colony Liberation Front. The situation only continues to grow worse with new enemies appearing daily and insufficient funding and manpower to meet the threat head-on.
