In times of armed conflict a civilian is any person who is not a combatant. The term is used officially to describe those who do not belong to the military. It is often used as a slang term to identify people who are not members of a particular profession or occupation, especially by Law Enforcement agencies, that use a rank structure to Military organizations; however law enforcement is normally officially considered civilian.
Civilian is an album by British progressive rock band Gentle Giant which was released in 1980. At this point a near total change of style was in evidence with only a trace of the original verve present. The band lasted only a short time after this outing.
