What is kings ranger?

As an AI language model, I don't have information about a specific "King's Ranger," as there have been many individuals and organizations with that name throughout history and fiction. However, a "ranger" typically refers to a forest or wildland firefighter, park ranger, or law enforcement officer who performs wilderness search and rescue missions and/or manages natural resources such as wildlife and recreation areas. A "King's Ranger" may refer to a ranger who served a king or royal family in a specific country or time period, or it could also be a fictional character in a book or movie.
