What is Guard World?

A Guard World refers to a planet or location that is primarily dedicated to defensive or protective purposes, often in the context of science fiction or fantasy settings such as Warhammer 40,000. In these universes, Guard Worlds are usually heavily fortified, garrisoned with military personnel, and equipped with advanced security measures to protect against invasions or threats. The term is not a standard job title in the real world, but rather a fictional concept related to planetary defense and security.
