The United Nations Marine Corps (UNMC) is the primary professional military force of the United Nations Navy (UNN). Well trained and equipped, they serve on-board UNN ships and stations. Like Martian Marines belonging to the Martian Marine Corps (MMC), UN Marines use powered, vacuum-rated armor, operate in a variety of combat environments, and utilise a variety of weapons and tactics.

Appearances Edit

At Anderson Station, Col. Fred Johnson of the UNMC was present during the incident, and it would be where he would gain his title as "The Butcher of Anderson Station".

A UN Marine unit was on duty on Ganymede at the time of the incident when they encountered Project Caliban and are assumed to have been killed in action.
