Civilian (Earth-5875)

A civilian is a person who is not a member of the military or of a police or firefighting force. The term "civilian" is slightly different from a non-combatant. Under humanitarian law, civilians are entitled to certain privileges, such as the Fourth Geneva Convention. They are protected by law enforcement agencies, and the main purpose of military organizations is often their defense. Some civilians, such as Dr. Catherine Halsey and Ellen Ripley are heavily involved with the military as civilian consultants. Civilians have their own identification numbers, which is attached to their personal data transmitters (PDTs), cybernetically inplanted on their brains.
