Description

The United States Colonial Marine Corps (USCMC) is a fictional military organization portrayed in the "Aliens" film franchise. Within the franchise's universe, the USCMC is a highly trained and specialized branch of the United States military. The primary purpose of the USCMC is to provide security, defense, and combat operations for human colonies established on extraterrestrial planets. They are responsible for safeguarding the interests of humanity, protecting colonists, and responding to threats posed by hostile alien species. USCMC often faces formidable enemies such as the xenomorphs, a highly aggressive and deadly alien species. Marines are equipped with advanced armor, including the iconic M56 smartgun harness and powered exoskeletons known as "power loaders," which enhance their combat capabilities.
