Civilian

In wars, civilians are people who are not members of any armed force to the conflict. It is a war crime under the law of armed conflict to deliberately target civilians with military attacks, along with numerous other considerations to minimize civilian casualties during times of war. Civilians engaging in hostilities are considered unlawful combatants, and lose their protection from attack.

It is slightly different from a non-combatant, because some non-combatants are not civilians (for example, people who are not in a military but support war effort or military operations, military chaplains, or military personnel who are serving with a neutral country). Civilians in the territories of a party to an armed conflict are entitled to certain privileges under the customary laws of war and international treaties such as the Fourth Geneva Convention. The privileges that they enjoy under international law depends on whether the conflict is a civil war or an international one.

More broadly, the term can refer to any people in the general public who are outside of a particular group. For example, when reporting on incidents, members of first responder services (such as firefighters and law enforcement) may colloquially refer to members of the public as civilians.
